Item	Description
KDC Server	FQDN of the domain controller used as the Kerberos KDC.
	The FQDN consists of the device's host name and domain name. For example,
	kdc01.support.hp.com is a fully qualified domain name, where kdc01 is the host
	name and support.hp.com is the domain name.
Principal Realm	Kerberos principal realm in the form principal@REALM.
	A unique principal name is associated with each Kerberos account. For the HP Jetdirect
	print server active directory account, the principal is the user name for the print server.
	A Kerberos realm is similar in concept to a Windows domain and contains all the
	users, computers and services within a Kerberos installation. The realm is case-
	sensitive, and is typically the DNS domain name specified in all uppercase characters.
	For example, if the domain name is hp.com, the realm is HP.COM.
Password	Password for the HP Jetdirect account configured on active directory.
Encryption Type	Encryption type supported by the HP Jetdirect print server.
