We have a NAC appliance with CAM and CAS. When somebody tries to load any external page, he is supposed to get the CAS authentication page. However, what he gets is a "not found" error message. If he types directly the IP of the CAS in the browser, then he does get the authentication page. After the authentication, the user can access to internet properly.
We have tried to recreate the certificates in the CAS but the result has been the same.
Does anybody have some idea about what can be happening?
