“Realm on the card was not found in the Kerberos Configuration File” error message

This error occurs during Smart Card login.

UPLOAD A KERBEROS CONFIGURATION FILE AND MAKE SURE THE REALM HAS BEEN ADDED TO THE FILE

The PKI Authentication settings do not support multiple Kerberos Realm entries. If multiple realms are needed, then you must create and upload a krbf5.conf file containing the needed realms. If you are already using a Kerberos configuration file, then verify that the missing realm has been added to the file correctly.

“Client [NAME] unknown” error message

This error indicates that the KDC being used to authenticate the user does not recognize the User Principal Name specified in the error message.

VERIFY THAT THE DOMAIN CONTROLLER INFORMATION IS CORRECT

1From the Embedded Web Server, click Settings > Device Solutions > Solutions (eSF) > PKI Authentication > Configure.

2If the Simple Kerberos Setup has been configured, then verify that the IP address or host name of the Domain Controller is correct.

3If you are using a Kerberos configuration file, then verify that the Domain Controller entry is correct.
