Chances are, your system keytab only has DES keys. Either download a new
keytab that has more enctypes or add:
allow_weak_crypto = true
to the [libdefaults] section of your krb5.conf.

If your system keytab is fine, then it may be that the cross-realm key
only has DES keys, but I bet it's your system keytab.
