Jakub, thankyou for your reply.

Indeed. My reading of kinit is that it should take the first principal in the list returned by klist. In my case thsi should be ibis$


# klist -k
  11 ibis$@NZWW.NZCORP.NET
  11 ibis$@NZWW.NZCORP.NET
  11 IBIS$@NZWW.NZCORP.NET
  11 IBIS$@NZWW.NZCORP.NET
  11 ibis$@NZWW.NZCORP.NET
  11 host/ibis@NZWW.NZCORP.NET
  11 host/ibis@NZWW.NZCORP.NET
  11 IBIS$@NZWW.NZCORP.NET
  11 host/ibis@NZWW.NZCORP.NET

This is expected, in AD the host/fqdn principal cannot be used to get a TGT. As you can see below, you are using the netbiosname$@realm principal to kinit which works fine.

If your configuration is using id_provider=ad I would have expected sssd to prefer the netbiosname$ principal, but if the selection fails or you are using the ldap provider, you can help sssd with the ldap_sasl_authid parameter.
