I can not find good documentation on kerveros authentication with Dovecot. Maybe i am googling the wrong thing but am quite confused now.

I am trying to setup kerberos so that i do not have to type in my password every time i login to a different server and my mail for mutt also for a learning process.

I have the following i can do a kinit and get a ticket ok klist return from my kerb server.

So now i want to setup this with dovecot but can not find a tutorial on this and its really annoying can anyone help me? I only thing that i have found was someone saying modify the dovecot.conf
from
mechanisms = plain
to
mechanisms = plain gssapi

I have checked the logs and am not getting any errors

Where do i go next? How do i kerberize services?

Thanks

So I am a step backwards now i run mutt with the configuration file

but am getting

No authenticators available

The problem seams that mutt is not trying to authenticate off kerberos and give me my ticket.

Can anyone help ?
