Did another test with Samba AD(ldap will follow) and noticed just 2 points:
- A not sudo delegated user gets a “403 - Forbidden” error window, when entering NetworkAdapter page. I had to close the error window. Clicking OK shows the error again.
- If you logout a delegated user, the url is kept, and if you login with a not delegated user for that specific page afterwards you get an empty “403 - Forbidden” page. Maybe redirect users to profile page per default?
