@Sami Ahmad

configure-kerberos.pngWhen enabling Kerberos on "configure Kerberos" page () please verify that all mandatory fields have been entered with correct value specially realm name. The value of realm name should be same as present in /etc/krb5.conf file on manually installed KDC server host

After that verify that "Test KDC Connection" works ok.

Verify that the admin principal and keytab that you have entered on this page can kinit successfully with the KDC server.

Hope this helps isolate the issue.

if you have customized any non-mandatory configuration on this page, please let us know so we can consider to analyze this issue.
