WLC - 188.8.131.52
ISE - 1.1.1
I'm new to ISE. I want to set up a very basic method for BYOD users to access our wireless network. I've set up an SSID for external Web Auth, where users get redirected to the ISE Guest Portal: https://184.108.40.206:8443/guestportal/Login.action
At that screen, users can enter their Active Directory credentials and login. Although the authentcation shows as successful under Operations -> Authentications, the user is redirected to the device registration page. On that page they see the message "We are unable to determine access privileges in order to access the network. Please contact your administrator." Their device MAC is listed, and they can enter a description but the "Register" button is greyed out.
I'm getting overwhelmed with the amount of documentation available as well as the new terminology. I'm familiar with using Windows RADIUS servers, but ISE is very foreign to me now. Is there any documentation to help me understand how access requests are processed?
