DESCRIPTION

ldappasswd is a tool to set the password of an LDAP user. ldappasswd uses the LDAPv3 Password Modify (RFC 3062) extended operation.

ldappasswd sets the password of associated with the user [or an optionally specified user]. If the new password is not specified on the command line and the user doesn't enable prompting, the server will be asked to generate a password for the user.

ldappasswd is neither designed nor intended to be a replacement for passwd(1) and should not be installed as such.

OPTIONS

−V[V]

Print version info. If −VV is given, only the version information is printed.

−d debuglevel

Set the LDAP debugging level to debuglevel. ldappasswd must be compiled with LDAP_DEBUG defined for this option to have any effect.

−n

Do not set password. (Can be useful when used in conjunction with −v or −d)

−v

Increase the verbosity of output. Can be specified multiple times.

−A

Prompt for old password. This is used instead of specifying the password on the command line.

−a oldPasswd

Set the old password to oldPasswd.

−t oldPasswdFile

Set the old password to the contents of oldPasswdFile.

−S

Prompt for new password. This is used instead of specifying the password on the command line.

−s newPasswd

Set the new password to newPasswd.

−T newPasswdFile

Set the new password to the contents of newPasswdFile.

−x

Use simple authentication instead of SASL.

−D binddn

Use the Distinguished Name binddn to bind to the LDAP directory. For SASL binds, the server is expected to ignore this value.

−W

Prompt for bind password. This is used instead of specifying the password on the command line.

−w passwd

Use passwd as the password to bind with.

−y passwdfile

Use complete contents of passwdfile as the password for simple authentication.

−H ldapuri

Specify URI(s) referring to the ldap server(s); only the protocol/host/port fields are allowed; a list of URI, separated by whitespace or commas is expected.

−h ldaphost

Specify an alternate host on which the ldap server is running. Deprecated in favor of −H.

−p ldapport

Specify an alternate TCP port where the ldap server is listening. Deprecated in favor of −H.

−e [!]ext[=extparam]

−E [!]ext[=extparam]

Specify general extensions with −e and passwd modify extensions with −E. '!' indicates criticality.

General extensions:

  [!]assert=<filter>    (an RFC 4515 Filter)
  !authzid=<authzid>    ("dn:<dn>" or "u:<user>")
  [!]bauthzid           (RFC 3829 authzid control)
  [!]chaining[=<resolve>[/<cont>]]
  [!]manageDSAit
  [!]noop
  ppolicy
  [!]postread[=<attrs>] (a comma-separated attribute list)
  [!]preread[=<attrs>]  (a comma-separated attribute list)
  [!]relax
  sessiontracking
  abandon,cancel,ignore (SIGINT sends abandon/cancel,
  or ignores response; if critical, doesn't wait for SIGINT.
  not really controls)

Passwd Modify extensions:

  (none)

−o opt[=optparam]]

Specify general options.

General options:

  nettimeout=<timeout>  (in seconds, or "none" or "max")
  ldif-wrap=<width>     (in columns, or "no" for no wrapping)

−O security−properties

Specify SASL security properties.

−I

Enable SASL Interactive mode. Always prompt. Default is to prompt only as needed.

−Q

Enable SASL Quiet mode. Never prompt.

−N

Do not use reverse DNS to canonicalize SASL host name.

−U authcid

Specify the authentication ID for SASL bind. The form of the ID depends on the actual SASL mechanism used.

−R realm

Specify the realm of authentication ID for SASL bind. The form of the realm depends on the actual SASL mechanism used.

−X authzid

Specify the requested authorization ID for SASL bind. authzid must be one of the following formats: dn:<distinguished name> or u: <username>.

−Y mech

Specify the SASL mechanism to be used for authentication. If it's not specified, the program will choose the best mechanism the server knows.

−Z[Z]

Issue StartTLS (Transport Layer Security) extended operation. If you use −ZZ, the command will require the operation to be successful
