Thanks a million in advance. You can do this three different ways: 1) You can do it with Kerberos. This is a bit tricky to get working, but it can be done. This will give you single-sign-on, and not just the same password. A large downside is that this is not supported by all interfaces, for examlpe it's not supported with JDBC or .NET. 2) You can use the native LDAP authentication that's available in 8.2. I specifically created it to be used in one of my own Active Directory installations, so I know it works there (thuogh it of course works with other LDAP installs as well). 3) You can use pam_ldap. Never done that myself, but I've heard of others having some problems with it before, so I would definitly advise you to use option 2 for simple LDAP auth. //Magnus
