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 Microsoft 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.
Key Version Number Version number for the encryption keys associated with the principal and password.
