I'm kinda starting from scratch on this one.
I have defined the web login page in Clearpass guest to use the Aruba vendor settings and the controller-initated login. I get the clickthrough page fine, but clicking through gives me an access denied(null) message on the screen above the form, and I see nothing in access tracker. I was able to generate the unclassifed RADIUS service last night, but I can't remember how and it's not happening any more.
Changing to server-initated gives me an unclassified webauthservice error in access tracker, and the error message on the clickthrough screen changes to invalid username or password.
Should I be using controller initiated or server initiated? And what service template should I be using?
