Table 5-10 Kerberos Settings page
Item Description
KDC Server Enter the Fully Qualified Domain Name (FQDN) of the domain controller used as the
Kerberos Key Distribution Center (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 Enter a Kerberos principal realm in the form principal@REALM.
In a Kerberos installation, 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
will typically be the DNS domain name specified in all uppercase characters (for
example, if the domain name is hp.com, the realm is HP.COM).
Password Enter the password for the HP Jetdirect account configured on Active Directory.
