rancher: ActiveDirectory Authentication/Site Access Settings Broken

What kind of request is this (question/bug/enhancement/feature request): bug

Steps to reproduce (least amount of steps as possible):

1. Add Activedirectory authentication
2. submit activedirectory authentication with test user

Result:

1. You cannot add any group the test user is not part of
2. You cannot add any user
3. when logging in to rancher U.I. with another admin level user, you can only add the groups you are part of to the authentication section.

Other details that may be helpful: It appears that when it calculates/compares principals, it only compares it to the currently logged in user.

I tested using another AD user in the test section and had the same trouble, I could only add groups he was in.
