Dovecot and IPA

[Kanwar Ranbir Sandhu]

Hello,

I'm trying to get Dovecot to use GSSAPI for authentication. I have an 
IPA server on CentOS 7 with a bunch of my servers attached to the IPA 
domain, including the server running Dovecot.

I've followed official documentation from Red Hat and read numerous wiki 
articles on how to configure Dovecot to get it to use GSSAPI correctly. 
I don't think I've done anything incorrectly, but it refuses to work. 
This is the error I'm seeing:

mailman02 dovecot: imap-login: Disconnected (tried to use unsupported 
auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, 
session=<QhWSqxofyAAKyAkM>

I don't understand why no username is being passed.  My mail client is 
Evolution 3.10.4.

FYI, Dovecot does work fine using a user/password file. I'm just trying 
to switch it over to GSSAPI so that I can manage passwords from one 
system.

Any help would be appreciated.

Regards,

Ranbir
