I try to setup Dovecot with Kerberos/GSSAPI and use this howto:

I also try https://wiki.dovecot.org/Authentication/Kerberos

I can login as windows user on win7 and access shares.
When I open Thunderbird I get the message:

"kerberos/gssapi ticket was not accepted"

For debuging I use Kerbtray.

The Tickets I get are:

|-- cifs/dc1.my.fqdn.com
|-- cifs/files.my.fqdn.com
|-- krbtgt/MY.FQDN.COM
|-- krbtgt/MY.FQDN.COM
|-- LDAP/dc1.my.fqdn.com/my.fqdn.com

There is *no* imap ticket.
