It has been a few months since I worked out all the settings to authenticate against samba's AD, but I think you can solve your problem by putting a home argument in your userdb{} stanza. If that doesn't work, and assuming you are authenticating using ldap lookups, let me know and I can share more of how I set things up...

Hello List,
we're currently working on the migration of our LDAP/Samba3-Domain to Samba4-Active-Directory. So far everything works fine. Postfix can deliver Mails using ProxyAddresses-Information from the AD and Dovecot delivers the mail.
Unfortunately when Postfix tells Dovecot to deliver the mail he submit the username without the AD-Domain part:
Feb 28 17:17:59 tpdc postfix/pickup[30396]: 5DDAE2C0C2B: uid=0 from=<root> Feb 28 17:17:59 tpdc postfix/cleanup[30402]: 5DDAE2C0C2B: message-id=20130228161759.5DDAE2C0C2B@mx0.concepts-and-training.de Feb 28 17:17:59 tpdc postfix/qmgr[30395]: 5DDAE2C0C2B: from=root@concepts-and-training.de, size=463, nrcpt=1 (queue active) Feb 28 17:17:59 tpdc dovecot: lda(dwitt): msgid=20130228161759.5DDAE2C0C2B@mx0.concepts-and-training.de: saved mail to INBOX Feb 28 17:17:59 tpdc postfix/local[30404]: 5DDAE2C0C2B: to=dwitt@concepts-and-training.de, orig_to=denis.witt@cat06.de, relay=local, delay=0.24, delays=0.1/0.01/0/0.13, dsn=2.0.0, status=sent (delivered to command: /usr/lib/dovecot/deliver) Feb 28 17:17:59 tpdc postfix/qmgr[30395]: 5DDAE2C0C2B: removed
So Dovecot saves the Mail to "/var/mail/dwitt/", which is fine for me. The Problem kicks in when I try to read my Mail. Dovecot uses "TESTDOM\dwitt" as username and so he didn't find the Mailbox and create a new one in "/var/mail/TESTDOM\dwitt".
I tried to fix it with auth_username_translation and auth_username_format but it doesn't work.
Any ideas?
Thanks!
