I'm not sure if this affects all ldap users, but since 1.18rc1 I couldn't login anymore using user(a)domain.tld like used in ispman. We used to use http://server/?o=ispman?mailRoutingAddress?sub?(uid=%25s) Since it's not using serverdb_get2 I updated that line to use http://server/?o=ispman?mailRoutingAddress,mailHost?sub?(uid=%25s) Which works 100% using ldap search It returns mailRoutingAddress = user_domain_tld@mailHost mailHost = mailHost so I had to also add to perdition.conf strip_domain remote_login Now that being said even with all that I'd get server null, looking into perditiondb_ldap.c I found that it wasn't setting the ref values. I had to changes these lines /* Build the return string */ if (returns[0]) user_str = &returns[0]; if (returns[1]) server_str = &returns[1]; if (returns[2]) port_str = &returns[2]; to look like this /* Build the return string */ if (returns[0]) *user_str = returns[0]; if (returns[1]) *server_str = returns[1]; if (returns[2]) *port_str = returns[2]; Now everything works 100%, server gets set as does the user, hope this helps others cause it was 4 days of hell for me :D --- TS http://southofheaven.org/ Chaos is the beginning and end, try dealing with the rest.
