I've tried to export a keytab for a system:
I am asked to enter password for principal root/admin@TEST.TEST! This user doesn't exist. I thought about using "Administrator": "kinit Administrator", then entered the known password. Tickets where created and available. Since exporting a keytab needs admin rights I suspected to be asked again for password for "administrator/admin@TEST.TEST" trying to export the keytab. Yes it was. The known Passwort for "Administrator" didn't match. The principal "administrator/admin@TEST.TEST" didn't even exist.
How do I export a keytab with UCS without any kerberos admin user (no user having "/admin" option set?
