It crashes at login (using PAM via pam_ldap to Active Directory). And no, it was the wrong core file <sheepish grin>. Here's the proper backtrace (with "password" instead of what I actually used ;) )

Well, this one is also broken. Some things that point to an invalid backtrace:

OK this one's actually the right core file *and* the right binary (the other was from dovecot-1.0-beta7.)

and here's (more or less) the auth sections from "dovecot -n"

and the migrating and proxy.imap/proxy.pop3 files didn't exist in this case (but may do for other users).
