Hi,
I wrote up something to do AD authentication from a Linux system.
This is for logging in, but you can probably do what you need for Dovecot.

Let me know what you think.

Dovecot needs a password DB where to perform authentication and a user DB where to retrieve home directory and uid/gid. With A.D. you can perform only the first: authorization but you should use Kerberos and PAM, not LDAP. Actually, a Microsoft extension to A.D. exists; it add unix style accounting to A.D., but I did not test it (ehi, it's Microsoft stuff! Do you really think it can work? ;-) For the user DB you should use static uid/gid and virtual mailboxes (a single Linux user that own all the mailboxes).
If you are interested, search the list archives to find my post where I rougly explained how to do it. Sorry for my terrible english.
Greets.
