Using LDAP with Active Directory

Getting your Linux box to talk with Active Directory is pretty straight forward. But doing it securely will need you to have installed your CA certificate into your trusted certificates.

Mostly I’ll only setup anything to do with LDAP/Active Directory is a specific application requires it, otherwise I’ll leave out the Windows authentication bit.

Dovecot, Postfix, Virtual Mailboxes and Active Directory

Well turns out that setting this up isn’t really as straight forward as simply treating Active Directory like LDAP. The main reason seems to be the way you need to authenticate and the limitations of doing any kind of user lookup whilst using auth_bind = yes, just doesn’t seem possible.

In order to resolve this is you have to live with having Dovecot use a static userdb table that returns the gid, uid and home – but then when you try to sort Postfix so that it delivers using Dovecot it fails because it cant use a static userdb to work out if the user account/mailbox exists or not.
