Hi Dovecot-Mailinglist!

I try to install a new Dovecot-Server with Kerberos-Authentification (Kerberos-Server is already authenticating user-account ). The following error-notice occurs when I use mail-programm Gnome Evolution to access IMAP-Account:

"Ordner konnte nicht geöffnet werden (Folder can not be opened)

The reported error was "GSSAPI-Legitimation ist fehlgeschlagen". (GSSAPI-Legitimation failed)

Is anybody able to help me???

Thanks in advance, Sandra

Dovecot Version: 2.1.17
