slapd−dnssrv — DNS SRV referral backend to slapd
ETCDIR/slapd.conf
The DNSSRV backend to slapd(8) serves up referrals based upon SRV resource records held in the Domain Name System.
This backend is experimental.
The DNSSRV backend has no backend nor database specific options. It is configured simply by "database dnssrv" followed a suffix directive, e.g. suffix "".
The dnssrv
      backend does not honor all ACL semantics as described in
      slapd.access(5). In fact,
      this backend only implements the search operation when the
      manageDSAit control
      (RFC 3296) is used, otherwise for every operation a referral,
      whenever appropriate, or an error is returned. Currently,
      there is no means to condition the returning of the referral
      by means of ACLs; no access control is implemented, except
      for read (=r) access
      to the returned entries, which is actually provided by the
      frontend. Note, however, that the information returned by
      this backend is collected through the DNS, so it is public by
      definition.
