Hi Everyone,
I'm running an IPA server on CentOS 7 successfully and now I want to
change my Dovecot setup to use GSSAPI for IMAP authentication instead
of a flat "userdb" file. I've already joined the Dovecot box to the IPA
domain - ssh and ipa policies and all that are working properly.
I read a number of articles on how to configure Dovecot for GSSAPI auth
and they all said the same thing (even Red Hat's official how to on it
agreed). But, when I set up Evolution on my Fedora 22 system to use
GSSAPI, Dovecot's log records this:
Sep 8 13:49:55 mailman02 dovecot: auth: Panic: file auth-request.c:
line 733 (auth_request_is_disabled_master_user): assertion failed:
(request->requested_login_user != NULL)

I've already asked on the Dovecot list about my GSSAPI auth problems
and was told that this is a bug in Dovecot which does not exist in the
latest release (I don't know when the problem was actually fixed).
My question is simply this: does anyone else have
dovecot-2.2.10-4.el7_0.1.x86_64 working with GSSAPI auth against an IPA
server? IPA is also running on CentOS 7.1.1503.

Ranbir
