The LDAP authentication needs to bind with the full DN, which is "cn=...". Specifying uid= doesn't make it a valid LDAP distinguished name. So unless your LDAP server is "tricky" (like the Microsoft one, which accepts both DN and "DOMAIN\username" in the login packet), there's nothing you can do I think. (well, you can also change all your DNs in the LDAP catalog, but that's likely to break a lot of other things) PostgreSQL 9.0 will allow you do do a search+bind to get the functionality you want. The change should be fairly standalone so you could probably have it backpatched if it's urgent for you, but since it's a new feature it's not something the community backpatches. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-general mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
