With current releases you can do this with PAM, assuming you're on a platform that can do PAM. If your platform can't do PAM (for example, Windows), you can't do LDAP auth. 8.2 will have direct LDAP authentication without PAM. > 2 is it advisable to do this ? Sure, I see no reason why not. Beware of insecure password transports though - you'll need to use SSL/TLS or similar to secure the connection if you're going across insecure networks. //Magnus
