Dear Dovecot Team,
I'm in the (long) process of migrating my whole email infrastructure. Of course, dovecot is in the place, and is working just fine.
Still, I have an issue: password expiration.
I'm now using FreeIPA backend for the user authentication, and it includes the capacity to expire passwords. Basically, it's an LDAP with fancy things, among them a field named krbPasswordExpiration (yes, that's kerberos).
In order to make things simple, I'd rather NOT force my users to set up a kerberos/gssapi/whatever on their personal computer (most of them will just have blank gaze if I start talking about that).
Is there a way to make Dovecot use that field? It's apparently a simple date in %Y%M%D%H%m%sZ format, so a pretty neat thing to test. If there's some support for that in Dovecot, that is.
One option would be the post login script, see: https://wiki.dovecot.org/PostLoginScripting
Can also hook a password expiry check in dovecot-lda to send periodic reminders, although that's a bit unorthodox.
