Over in ClearPass Guest, you need to make sure that you changed the NAS Login to Cisco for the Guest Self-Registration page.
Some info about the Guest Login process:
When you login, there are two things happening:
- Pre-auth check (we check to make sure the account is valid and not disabled)
- NAS Login (your browser does a POST to the Login Form on the controller at 1.1.1.1)
When number 2 occurs, the controller should generate a RADIUS request to ClearPass.
Other than that, you should be all set, as long as the request from the WLC hits the appropriate service in CPPM based on the service rules.
Thanks,
Zach
