#25 Cannot add or modify Kerberos Realms

[Amanda]

Steps to reproduce:

1. Click Kerberos
2. Select Server
3. Click Kerberos Realms

Result: One existing realm, and a blank "realm" name
entry area, but no way to save anything added here -
there is no Save button, and hanges made do not persist.

4. Click "Modify" on existing realm

Results: get a popup error with the text "null". Cannot
modify this realm.
