Unable to view the list of principals or policies; use the Name field.
Cause: The admin principal that you logged in with does not have the list privilege (l) in the Kerberos ACL file (kadm5.acl). So, you cannot view the principal list or policy list.
Solution: You must type the principal and policy names in the Name field to work on them, or you need to log in with a principal that has the appropriate privileges.
JNI: Java * failed
Cause: A serious problem exists with the Java Native Interface that is used by the gkadmin GUI.
Solution: Exit gkadmin and restart it. If the problem persists, report a bug.
