 +------------------+ Configuring Kerberos Authentication +------------------+
 | When users attempt to use Kerberos and specify a principal or user name   |
 | without specifying what administrative Kerberos realm that principal      |
 | belongs to, the system appends the default realm.  The default realm may  |
 | also be used as the realm of a Kerberos service running on the local      |
 | machine.  Often, the default realm is the uppercase version of the local  |
 | DNS domain.                                                               |
