Table 5-10 Kerberos Settings page
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.
