Hello.

We are using dovecot right now, but the boss pushes the MS based system (Exchange, Sharepoint, Active Directory etc) to use. However, skipping the other parts I'd like to keep open source based mail server and the question is - can the dovecot authenticate against the MS Active Directory without any problems?

We do this ourselves using PAM (passdb=pam), pam_ldap and a passwd-file for the userdb (generated from NIS and really only used to map usernames to UNIX uids - you could, of course, use "static" instead).

Since we went down this route, Dovecot's own LDAP support has improved, and it may be possible to miss the PAM/pam_ldap stage (which has the disadvantage of opening a new LDAP connection to the Active Directory for each authentication).

It's worth searching the list archives for example configurations for this (I'm pretty sure I sent ours sometime in the autumn).

Best Wishes, Chris
