dovecot, winbind and user folders

Folks;

I'm in the process of migrating an existing IMAP infrastructure to something that should be dovecot based. We live inside a Windows AD 2012 realm and the servers use winbind for user authentication as well as pam configurations to automatically create user home dirs whenever the user logs in first.

Can something like this (mailbox is automatically generated whenever user logs in first) be done with dovecot too? Any best practises on how to work in such setups? I want to keep setup effort required for new users as low as possible... ;)

Thanks in advance and all the best, Kristian
