Grant access (specified by <access>) to a set of entries and/or attributes (specified by <what>) by one or more requestors (specified by <who>). If no access controls are present, the default policy allows anyone and everyone to read anything but restricts updates to rootdn. (e.g., "access to * by * read"). The rootdn can always read and write EVERYTHING! See slapd.access(5) and the "OpenLDAP's Administrator's Guide" for details.

Specify a set of features (separated by white space) to allow (default none). bind_v2 allows acceptance of LDAPv2 bind requests. Note that slapd(8) does not truly implement LDAPv2 (RFC 1777), now Historic (RFC 3494). bind_anon_cred allows anonymous bind when credentials are not empty (e.g. when DN is empty). bind_anon_dn allows unauthenticated (anonymous) bind when DN is not empty. update_anon allows unauthenticated (anonymous) update operations to be processed (subject to access controls and other administrative limits). proxy_authz_anon allows unauthenticated (anonymous) proxy authorization control to be processed (subject to access controls, authorization and other administrative limits).

The (absolute) name of a file that will hold the slapd server's command line (program name and options).

Define tagging attribute options or option tag/range prefixes. Options must not end with `−', prefixes must end with `−'. The `lang−' prefix is predefined. If you use the attributeoptions directive, `lang−' will no longer be defined and you must specify it explicitly if you want it defined.

An attribute description with a tagging option is a subtype of that attribute description without the option. Except for that, options defined this way have no special semantics. Prefixes defined this way work like the `lang−' options: They define a prefix for tagging options starting with the prefix. That is, if you define the prefix `x−foo−', you can use the option `x−foo−bar'. Furthermore, in a search or compare, a prefix or range name (with a trailing `−') matches all options starting with that name, as well as the option with the range name sans the trailing `−'. That is, `x−foo−bar−' matches `x−foo−bar' and `x−foo−bar−baz'.

RFC 4520 reserves options beginning with `x−' for private experiments. Other options should be registered with IANA, see RFC 4520 section 3.5. OpenLDAP also has the `binary' option built in, but this is a transfer option, not a tagging option.

attributetype ( <oid> [NAME <name>] [DESC <description>] [OBSOLETE] [SUP <oid>] [EQUALITY <oid>] [ORDERING <oid>] [SUBSTR <oid>] [SYNTAX <oidlen>] [SINGLE−VALUE] [COLLECTIVE] [NO−USER−MODIFICATION] [USAGE <attributeUsage>] )

Used by the authentication framework to convert simple user names to an LDAP DN used for authorization purposes. Its purpose is analogous to that of authz-regexp (see below). The prefix authid− is followed by a set of rules analogous to those described in slapo-rwm(5) for data rewriting (replace the rwm− prefix with authid−). authid−rewrite<cmd> and authz−regexp rules should not be intermixed.

Used to specify which rules to use for Proxy Authorization. Proxy authorization allows a client to authenticate to the server using one user's credentials, but specify a different identity to use for authorization and access control purposes. It essentially allows user A to login as user B, using user A's password. The none flag disables proxy authorization. This is the default setting. The from flag will use rules in the authzFrom attribute of the authorization DN. The to flag will use rules in the authzTo attribute of the authentication DN. The any flag, an alias for the deprecated value of both, will allow any of the above, whatever succeeds first (checked in to, from sequence. The all flag requires both authorizations to succeed.

Used by the authentication framework to convert simple user names, such as provided by SASL subsystem, or extracted from certificates in case of cert-based SASL EXTERNAL, or provided within the RFC 4370 "proxied authorization" control, to an LDAP DN used for authorization purposes. Note that the resulting DN need not refer to an existing entry to be considered valid. When an authorization request is received from the SASL subsystem, the SASL USERNAME, REALM, and MECHANISM are taken, when available, and combined into a name of the form

Specify a desired level of concurrency. Provided to the underlying thread system as a hint. The default is not to provide any hint.

Specify the maximum number of pending requests for an anonymous session. If requests are submitted faster than the server can process them, they will be queued up to this limit. If the limit is exceeded, the session is closed. The default is 100.

Specify the maximum number of pending requests for an authenticated session. The default is 1000.

Specify a default search base to use when client submits a non-base search request with an empty base DN. Base scoped search requests with an empty base DN are not affected.

Specify a set of features (separated by white space) to disallow (default none). bind_anon disables acceptance of anonymous bind requests. Note that this setting does not prohibit anonymous directory access (See "require authc"). bind_simple disables simple (bind) authentication. tls_2_anon disables forcing session to anonymous status (see also tls_authc) upon StartTLS operation receipt. tls_authc disallows the StartTLS operation if authenticated (see also tls_2_anon). proxy_authz_non_critical disables acceptance of the proxied authorization control (RFC4370) when criticality is FALSE. dontusecopy_non_critical disables acceptance of the dontUseCopy control (a work in progress) when criticality is FALSE.

ditcontentrule ( <oid> [NAME <name>] [DESC <description>] [OBSOLETE] [AUX <oids>] [MUST <oids>] [MAY <oids>] [NOT <oids>] )

A SIGHUP signal will only cause a 'gentle' shutdown-attempt: Slapd will stop listening for new connections, but will not close the connections to the current clients. Future write operations return unwilling-to-perform, though. Slapd terminates when all clients have closed their connections (if they ever do), or - as before - if it receives a SIGTERM signal. This can be useful if you wish to terminate the server and start a new slapd server with another database, without disrupting the currently active clients. The default is off. You may wish to use idletimeout along with this option.

Specify the number of seconds to wait before forcibly closing an idle client connection. A idletimeout of 0 disables this feature. The default is 0. You may also want to set the writetimeout option.

Read additional configuration information from the given file before continuing with the next line of the current file.

Specify the key length for ordered integer indices. The most significant bytes of the binary integer will be used for index keys. The default value is 4, which provides exact indexing for 31 bit values. A floating point representation is used to index too large values.

Specify the minimum length for subinitial and subfinal indices. An attribute value must have at least this many characters in order to be processed by the indexing functions. The default is 2.

Specify the maximum length for subinitial and subfinal indices. Only this many characters of an attribute value will be processed by the indexing functions; any excess characters are ignored. The default is 4.

Specify the length used for subany indices. An attribute value must have at least this many characters in order to be processed. Attribute values longer than this length will be processed in segments of this length. The default is 4. The subany index will also be used in subinitial and subfinal index lookups when the filter string is longer than the index_substr_if_maxlen value.

Specify the steps used in subany index lookups. This value sets the offset for the segments of a filter string that are processed for a subany index lookup. The default is 2. For example, with the default values, a search using this filter "cn=*abcdefgh*" would generate index lookups for "abcd", "cdef", and "efgh".

	Note
	Indexing support depends on the particular backend in use. Also, changing these settings will generally require deleting any indices that depend on these parameters and recreating them with slapindex(8).

ldapsyntax ( <oid> [DESC <description>] [X−SUBST <substitute-syntax>] )

Specify the number of threads to use for the connection manager. The default is 1 and this is typically adequate for up to 16 CPU cores. The value should be set to a power of 2.

Specifies the Security Strength Factor (SSF) to be given local LDAP sessions, such as those to the ldapi:// listener. For a description of SSF values, see sasl-secprops's minssf option description. The default is 71.

Specify a file for recording debug log messages. By default these messages only go to stderr and are not recorded anywhere else. Specifying a logfile copies messages to both stderr and the logfile.

Specify the level at which debugging statements and operation statistics should be syslogged (currently logged to the syslogd(8) LOG_LOCAL4 facility). They must be considered subsystems rather than increasingly verbose log levels. Some messages with higher priority are logged regardless of the configured loglevel as soon as any logging is configured. Log levels are additive, and available levels are:

Specify the name of a dynamically loadable module to load. The filename may be an absolute path name or a simple filename. Non-absolute names are searched for in the directories specified by the modulepath option. This option and the modulepath option are only usable if slapd was compiled with −−enable−modules.

Specify a list of directories to search for loadable modules. Typically the path is colon-separated but this depends on the operating system. The default is MODULEDIR, which is where the standard OpenLDAP install will place its modules.

objectclass ( <oid> [NAME <name>] [DESC <description>] [OBSOLETE] [SUP <oids>] [{ ABSTRACT | STRUCTURAL | AUXILIARY }] [MUST <oids>] [MAY <oids>] )

Define a string name that equates to the given OID. The string can be used in place of the numeric OID in objectclass and attribute definitions. The name can also be used with a suffix of the form ":xx" in which case the value "oid.xx" will be used.

This option configures one or more hashes to be used in generation of user passwords stored in the userPassword attribute during processing of LDAP Password Modify Extended Operations (RFC 3062). The <hash> must be one of {SSHA}, {SHA}, {SMD5}, {MD5}, {CRYPT}, and {CLEARTEXT}. The default is {SSHA}.

{SHA} and {SSHA} use the SHA-1 algorithm (FIPS 160-1), the latter with a seed.

{MD5} and {SMD5} use the MD5 algorithm (RFC 1321), the latter with a seed.

{CRYPT} uses the crypt(3).

{CLEARTEXT} indicates that the new password should be added to userPassword as clear text.

Note that this option does not alter the normal user applications handling of userPassword during LDAP Add, Modify, or other LDAP operations.

Specify the format of the salt passed to crypt(3) when generating {CRYPT} passwords (see password−hash) during processing of LDAP Password Modify Extended Operations (RFC 3062).

This string needs to be in sprintf(3) format and may include one (and only one) %s conversion. This conversion will be substituted with a string of random characters from [A−Za−z0−9./]. For example, "%.2s" provides a two character salt and "$1$%.8s" tells some versions of crypt(3) to use an MD5 algorithm and provides 8 random characters of salt. The default is "%s", which provides 31 characters of salt.

The (absolute) name of a file that will hold the slapd server's process ID (see getpid(2)).

Specify the referral to pass back when slapd(8) cannot find a local database to handle a request. If specified multiple times, each url is provided.

Specify a set of conditions (separated by white space) to require (default none). The directive may be specified globally and/or per-database; databases inherit global conditions, so per-database specifications are additive. bind requires bind operation prior to directory operations. LDAPv3 requires session to be using LDAP version 3. authc requires authentication prior to directory operations. SASL requires SASL authentication prior to directory operations. strong requires strong authentication prior to directory operations. The strong keyword allows protected "simple" authentication as well as SASL authentication. none may be used to require no conditions (useful to clear out globally set conditions within a particular database); it must occur first in the list of conditions.

Enable/disable client name unverified reverse lookup (default is off if compiled with −−enable−rlookups).

Specify the name of an LDIF(5) file containing user defined attributes for the root DSE. These attributes are returned in addition to the attributes normally produced by slapd.

The root DSE is an entry with information about the server and its capabilities, in operational attributes. It has the empty DN, and can be read with e.g.:

See RFC 4512 section 5.1 for details.

Specify which auxprop plugins to use for authentication lookups. The default is empty, which just uses slapd's internal support. Usually no other auxprop plugins are needed.

Used to specify the fully qualified domain name used for SASL processing.

Specify SASL realm. Default is empty.

Used to specify Cyrus SASL security properties. The none flag (without any other properties) causes the flag properties default, "noanonymous,noplain", to be cleared. The noplain flag disables mechanisms susceptible to simple passive attacks. The noactive flag disables mechanisms susceptible to active attacks. The nodict flag disables mechanisms susceptible to passive dictionary attacks. The noanonymous flag disables mechanisms which support anonymous login. The forwardsec flag require forward secrecy between sessions. The passcred require mechanisms which pass client credentials (and allow mechanisms which can pass credentials to do so). The minssf=<factor> property specifies the minimum acceptable security strength factor as an integer approximate to effective key length used for encryption. 0 (zero) implies no protection, 1 implies integrity protection only, 56 allows DES or other weak ciphers, 112 allows triple DES and other strong ciphers, 128 allows RC4, Blowfish and other modern strong ciphers. The default is 0. The maxssf=<factor> property specifies the maximum acceptable security strength factor as an integer (see minssf description). The default is INT_MAX. The maxbufsize=<size> property specifies the maximum security layer receive buffer size allowed. 0 disables security layers. The default is 65536.

Specify the distinguished name for the subschema subentry that controls the entries on this server. The default is "cn=Subschema".

Specify a set of security strength factors (separated by white space) to require (see sasl−secprops's minssf option for a description of security strength factors). The directive may be specified globally and/or per-database. ssf=<n> specifies the overall security strength factor. transport=<n> specifies the transport security strength factor. tls=<n> specifies the TLS security strength factor. sasl=<n> specifies the SASL security strength factor. update_ssf=<n> specifies the overall security strength factor to require for directory updates. update_transport=<n> specifies the transport security strength factor to require for directory updates. update_tls=<n> specifies the TLS security strength factor to require for directory updates. update_sasl=<n> specifies the SASL security strength factor to require for directory updates. simple_bind=<n> specifies the security strength factor required for simple username/password authentication. Note that the transport factor is measure of security provided by the underlying transport, e.g. ldapi:// (and eventually IPSEC). It is not normally used.

Specify an integer ID from 0 to 4095 for this server (limited to 3 hexadecimal digits). The ID may also be specified as a hexadecimal ID by prefixing the value with "0x". These IDs are required when using multimaster replication and each master must have a unique ID. Note that this requirement also applies to separate masters contributing to a glued set of databases. If the URL is provided, this directive may be specified multiple times, providing a complete list of participating servers and their IDs. The fully qualified hostname of each server should be used in the supplied URLs. The IDs are used in the "replica id" field of all CSNs generated by the specified server. The default value is zero. Example:

        serverID 1

Specify the maximum number of entries to return from a search operation. The default size limit is 500. Use unlimited to specify no limits. The second format allows a fine grain setting of the size limits. Extra args can be added on the same line. See limits for an explanation of the different flags.

Specify the maximum incoming LDAP PDU size for anonymous sessions. The default is 262143.

Specify the maximum incoming LDAP PDU size for authenticated sessions. The default is 4194303.

Specify a list of multi-valued attributes whose values will always be maintained in sorted order. Using this option will allow Modify, Compare, and filter evaluations on these attributes to be performed more efficiently. The resulting sort order depends on the attributes' syntax and matching rules and may not correspond to lexical order or any other recognizable order.

Specify the size of the TCP buffer. A global value for both read and write TCP buffers related to any listener is defined, unless the listener is explicitly specified, or either the read or write qualifiers are used. See tcp(7) for details. Note that some OS-es implement automatic TCP buffer tuning.

Specify the maximum size of the primary thread pool. The default is 16; the minimum value is 2.

Specify the maximum number of seconds (in real time) slapd will spend answering a search request. The default time limit is 3600. Use unlimited to specify no limits. The second format allows a fine grain setting of the time limits. Extra args can be added on the same line. See limits for an explanation of the different flags.

Specify the maximum number of threads to use in tool mode. This should not be greater than the number of CPUs in the system. The default is 1.

Specify the number of seconds to wait before forcibly closing a connection with an outstanding write. This allows recovery from various network hang conditions. A writetimeout of 0 disables this feature. The default is 0.

Permits configuring what ciphers will be accepted and the preference order. <cipher-suite-spec> should be a cipher specification for the TLS library in use (OpenSSL, GnuTLS, or Mozilla NSS). Example:

Specifies the file that contains certificates for all of the Certificate Authorities that slapd will recognize. The certificate for the CA that signed the server certificate must be included among these certificates. If the signing CA was not a top-level (root) CA, certificates for the entire sequence of CA's from the signing CA to the top-level CA should be present. Multiple certificates are simply appended to the file; the order is not significant.

Specifies the path of a directory that contains Certificate Authority certificates in separate individual files. Usually only one of this or the TLSCACertificateFile is used. This directive is not supported when using GnuTLS.

When using Mozilla NSS, <path> may contain a Mozilla NSS cert/key database. If <path> contains a Mozilla NSS cert/key database and CA cert files, OpenLDAP will use the cert/key database and will ignore the CA cert files.

Specifies the file that contains the slapd server certificate.

When using Mozilla NSS, if using a cert/key database (specified with TLSCACertificatePath), TLSCertificateFile specifies the name of the certificate to use:

        TLSCertificateFile Server-Cert

If using a token other than the internal built in token, specify the token name first, followed by a colon:

        TLSCertificateFile my hardware device:Server-Cert

Use certutil -L to list the certificates by name:

        certutil -d /path/to/certdbdir -L

Specifies the file that contains the slapd server private key that matches the certificate stored in the TLSCertificateFile file. Currently, the private key must not be protected with a password, so it is of critical importance that it is protected carefully.

When using Mozilla NSS, TLSCertificateKeyFile specifies the name of a file that contains the password for the key for the certificate specified with TLSCertificateFile. The modutil command can be used to turn off password protection for the cert/key database. For example, if TLSCACertificatePath specifes /etc/openldap/certdb as the location of the cert/key database, use modutil to change the password to the empty string:

        modutil -dbdir /etc/openldap/certdb -changepw 'NSS Certificate DB'

You must have the old password, if any. Ignore the WARNING about the running browser. Press 'Enter' for the new password.

This directive specifies the file that contains parameters for Diffie-Hellman ephemeral key exchange. This is required in order to use a DSA certificate on the server. If multiple sets of parameters are present in the file, all of them will be processed. Note that setting this option may also enable Anonymous Diffie-Hellman key exchanges in certain non-default cipher suites. You should append "!ADH" to your cipher suites if you have changed them from the default, otherwise no certificate exchanges or verification will be done. When using GnuTLS these parameters are always generated randomly so this directive is ignored. This directive is ignored when using Mozilla NSS.

Specifies minimum SSL/TLS protocol version that will be negotiated. If the server doesn't support at least that version, the SSL handshake will fail. To require TLS 1.x or higher, set this option to 3.(x+1), e.g.,

        TLSProtocolMin 3.2

would require TLS 1.1. Specifying a minimum that is higher than that supported by the OpenLDAP implementation will result in it requiring the highest level that it does support. This directive is ignored with GnuTLS.

Specifies the file to obtain random bits from when /dev/[u]random is not available. Generally set to the name of the EGD/PRNGD socket. The environment variable RANDFILE can also be used to specify the filename. This directive is ignored with GnuTLS and Mozilla NSS.

Specifies what checks to perform on client certificates in an incoming TLS session, if any. The <level> can be specified as one of the following keywords:

Specifies if the Certificate Revocation List (CRL) of the CA should be used to verify if the client certificates have not been revoked. This requires TLSCACertificatePath parameter to be set. This directive is ignored with GnuTLS and Mozilla NSS. <level> can be specified as one of the following keywords:

Specifies a file containing a Certificate Revocation List to be used for verifying that certificates have not been revoked. This directive is only valid when using GnuTLS and Mozilla NSS.

Mark the beginning of a backend definition. <databasetype> should be one of bdb, config, dnssrv, hdb, ldap, ldif, mdb, meta, monitor, null, passwd, perl, relay, shell, or sql, depending on which backend will serve the database.

Mark the beginning of a new database instance definition. <databasetype> should be one of bdb, config, dnssrv, hdb, ldap, ldif, mdb, meta, monitor, null, passwd, perl, relay, shell, or sql, depending on which backend will serve the database.

LDAP operations, even subtree searches, normally access only one database. That can be changed by gluing databases together with the subordinate keyword. Access controls and some overlays can also involve multiple databases.

Controls whether Add operations will perform ACL checks on the content of the entry being added. This check is off by default. See the slapd.access(5) manual page for more details on ACL requirements for Add operations.

Lists what attributes need to be added to search requests. Local storage backends return the entire entry to the frontend. The frontend takes care of only returning the requested attributes that are allowed by ACLs. However, features like access checking and so may need specific attributes that are not automatically returned by remote storage backends, like proxy backends and so on. <attrlist> is a list of attributes that are needed for internal purposes and thus always need to be collected, even when not explicitly requested by clients.

Controls whether the database will be used to answer queries. A database that is hidden will never be selected to answer any queries, and any suffix configured on the database will be ignored in checks for conflicts with other databases. By default, hidden is off.

Controls whether slapd will automatically maintain the modifiersName, modifyTimestamp, creatorsName, and createTimestamp attributes for entries. It also controls the entryCSN and entryUUID attributes, which are needed by the syncrepl provider. By default, lastmod is on.

Specify time and size limits based on the operation's initiator or base DN. The argument <selector> can be any of

Specifies the maximum number of aliases to dereference when trying to resolve an entry, used to avoid infinite alias loops. The default is 15.

This option puts a replica database into "mirror" mode. Update operations will be accepted from any user, not just the updatedn. The database must already be configured as a syncrepl consumer before this keyword may be set. This mode also requires a serverID (see above) to be configured. By default, mirrormode is off.

This option enables database-specific monitoring in the entry related to the current database in the "cn=Databases,cn=Monitor" subtree of the monitor database, if the monitor database is enabled. Currently, only the BDB and the HDB databases provide database-specific monitoring. The default depends on the backend type.

Add the specified overlay to this database. An overlay is a piece of code that intercepts database operations in order to extend or change them. Overlays are pushed onto a stack over the database, and so they will execute in the reverse of the order in which they were configured and the database itself will receive control last of all. See the slapd.overlays(5) manual page for an overview of the available overlays. Note that all of the database's regular settings should be configured before any overlay settings.

This option puts the database into "read-only" mode. Any attempts to modify the database will return an "unwilling to perform" error. By default, readonly is off.

Specify a whitespace separated list of operations that are restricted. If defined inside a database specification, restrictions apply only to that database, otherwise they are global. Operations can be any of add, bind, compare, delete, extended[=<OID>], modify, rename, search, or the special pseudo-operations read and write, which respectively summarize read and write operations. The use of restrict write is equivalent to readonly on (see above). The extended keyword allows to indicate the OID of the specific operation to be restricted.

Specify the distinguished name that is not subject to access control or administrative limit restrictions for operations on this database. This DN may or may not be associated with an entry. An empty root DN (the default) specifies no root access is to be granted. It is recommended that the rootdn only be specified when needed (such as when initially populating a database). If the rootdn is within a namingContext (suffix) of the database, a simple bind password may also be provided using the rootpw directive. Many optional features, including syncrepl, require the rootdn to be defined for the database.

Specify a password (or hash of the password) for the rootdn. The password can only be set if the rootdn is within the namingContext (suffix) of the database. This option accepts all RFC 2307 userPassword formats known to the server (see password−hash description) as well as cleartext. slappasswd(8) may be used to generate a hash of a password. Cleartext and {CRYPT} passwords are not recommended. If empty (the default), authentication of the root DN is by other means (e.g. SASL). Use of SASL is encouraged.

Specify the DN suffix of queries that will be passed to this backend database. Multiple suffix lines can be given and at least one is required for each database definition.

If the suffix of one database is "inside" that of another, the database with the inner suffix must come first in the configuration file. You may also want to glue such databases together with the subordinate keyword.

Specify that the current backend database is a subordinate of another backend database. A subordinate database may have only one suffix. This option may be used to glue multiple databases into a single namingContext. If the suffix of the current database is within the namingContext of a superior database, searches against the superior database will be propagated to the subordinate as well. All of the databases associated with a single namingContext should have identical rootdns. Behavior of other LDAP operations is unaffected by this setting. In particular, it is not possible to use moddn to move an entry from one subordinate to another subordinate within the namingContext.

If the optional advertise flag is supplied, the naming context of this database is advertised in the root DSE. The default is to hide this database context, so that only the superior context is visible.

If the slap tools slapcat(8), slapadd(8), or slapindex(8) are used on the superior database, any glued subordinates that support these tools are opened as well.

Databases that are glued together should usually be configured with the same indices (assuming they support indexing), even for attributes that only exist in some of these databases. In general, all of the glued databases should be configured as similarly as possible, since the intent is to provide the appearance of a single directory.

Note that the subordinate functionality is implemented internally by the glue overlay and as such its behavior will interact with other overlays in use. By default, the glue overlay is automatically configured as the last overlay on the superior backend. Its position on the backend can be explicitly configured by setting an overlay glue directive at the desired position. This explicit configuration is necessary e.g. when using the syncprov overlay, which needs to follow glue in order to work over all of the glued databases. E.g.

Store the syncrepl contextCSN in a subentry instead of the context entry of the database. The subentry's RDN will be "cn=ldapsync". By default the contextCSN is stored in the context entry.

This option is only applicable in a slave database. It specifies the DN permitted to update (subject to access controls) the replica. It is only needed in certain push-mode replication scenarios. Generally, this DN should not be the same as the rootdn used at the master.

Specify the referral to pass back when slapd(8) is asked to modify a replicated local database. If specified multiple times, each url is provided.
