[Dovecot] Dovecot auth GSSAPI

[Eduardo Sachs]

Hi,

    I have Heimdal Kerberos with authentication in my Samba PDC, Postfix 
and OpenLDAP, it is perfect.

    But, I have problem with authentication GSSAPI of Dovecot.

    I install a service ticket of the form 
imap/mailserver.domain.com at REALM, imap/mailserver at REALM, 
pop/mailserver.domain.com at REALM and pop/mailserver at REALM and 
/etc/krb5.keytab for this services tickets.

    Debug in my messages log:

Jan  9 15:14:32 mailserver dovecot: auth(default): client in: 
AUTH^I1^IGSSAPI^Iservice=IMAP^Ilip=192.168.0.71^Irip=192.168.0.212
