Only one that I would recommend, called SKS.  You can get it from

There are others, but they are either not finished yet (cks), or don't
work with modern keys (pks).

These programs use a different backend database than LDAP.  You could
modify them to use LDAP if you liked.

Yes and no.  There is a PGP product which is a LDAP keyserver.  It it
not a true LDAP server, but rather a keyserver that happens to speak
LDAP.  You can't use it to store non-key data.

The latest version of PGP (8) also supports using a regular LDAP
server as a key store.  GnuPG does not yet support this, but will
probably support it in version 1.4.  The disadvantage to this is that
the server operator needs to have some authentication scheme on the
LDAP server to prevent people from replacing keys that do not belong
to them.  The authentication system for this type of setup is LDAP
itself, and is external to PGP or GnuPG.

Version: GnuPG v1.2.3rc1 (GNU/Linux)
