The Use Selected Realm feature is applicable only if the login methods for card registration and manual login are Kerberos, Active Directory, or LDAP+GSSAPI. This feature is also applicable only if card validation is set to Web Service or Printer-based.
For card registration, if this feature is enabled, then the badge ID that is registered is in username@realm format.
For manual login, if this feature is enabled, then the user name shown in the printer control panel is in username@realm format.
These settings do not apply to PIN login and PIN registration.
To enable this feature, do the following:
From the Embedded Web Server, navigate to the configuration page for the application:
Apps > Card Authentication > Configure
From the Advanced Settings section, select Use Selected Realm.
Click Save.
