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@REALM, imap/mailserver@REALM, pop/mailserver.domain.com@REALM and pop/mailserver@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 Jan 9 15:14:32 mailserver dovecot: auth(default): gssapi(?,192.168.0.212): Obtaining credentials for imap@mailserver Jan 9 15:14:32 mailserver dovecot: auth(default): gssapi(?,192.168.0.212): While importing principal name: An invalid name was supplied Jan 9 15:14:33 mailserver dovecot: auth(default): client out: FAIL^I1^Itemp Jan 9 15:14:33 mailserver dovecot: imap-login: Aborted login: method=GSSAPI, rip=192.168.0.212, lip=192.168.0.71
Someone knows solve this problem? Or, it is a bug?
