2. Enter the following:

Enable Kerberos	Displays selected if you enabled this method on the User
	Authentication page. If you want to set up this authentication
	method but not enable it immediately, clear the checkbox.
	Note: You can enable Kerberos here or on the first User
	Authentication page. If you enable Kerberos here, it automatically
	displays at the end of the order of precedence on the User
	Authentication page.
Realm	Enter the name of the logical network served by a single Kerberos
	database and a set of Key Distribution Centers. Usually, realm
	names are all uppercase letters to differentiate the realm from the
	Internet domain. Realm is similar in concept to an NT domain.
KDC	A key distribution center (KDC) is a server that issues Kerberos
	tickets. A ticket is a temporary set of electronic credentials that
	verify the identity of a client for a particular service.
	Enter the KDC in the fully qualified domain format (FQDN). An
	example is SLB.local.
