I hit a small snag using Dovecot-imapd smoothly in my environment with maildir and most of my accounts in LDAP. Since the accounts are created through a web interface on another server home directories on the mail server don't get created automatically. There's the handy pam module pam_mkhomedir.so to automagically create home directories, but unfortunatly Dovecot wasn't calling pam_open_session to run the session setup pam modules. I made a small patch to passdb-pam.c to call pam_open_session between pam_acct_mgmt and pam_get_item and now I my home dirs are automagically created and everyone is happy.
So, I figured I'd share the little patch in case someone else finds it useful. My patch doesn't properly close the session which will probably iritate more advanced session modules that actually have something to clean up, oh well.
Aside from manually having to create home directories Dovecot-imapd has been working really well for us for a number of months, I just finally got around to dealing with the home dir creation issue.
