Hi,
how i can link the controller with the policy manager?
You can setup a the RADIUS connection between your Aruba Controller and the Policy Manager.
Check Page 275 of this doc for details Aruba 6.1 doc
Then just be sure to configure your VAP (Virtual AP) to use the RADIUS correctly
Once you have setup your shared key create the link from the Policy Manager side:
Configuration > Network Devices > Add Device
Drop in the IP and the shared key and you should be good to go.
From there you can then create a simple Guest Self-Registration form to test with. Link this Guest Self-Registration to a Captive Portal Profile on your Controller.
how i can configure the policy for the guests users?
You have to understand how the Services work. This is the part we struggled with when we first started our implementation of CPPM with our Aruba Controller.
My recommendation is once you start seeing information hitting your CPPM study the logs in the Access Tracker (Monitoring > Live Monitoring > Access Tracker). Get familiar with the information available in your logs and you can start to build your policies around that set of information. You can then do things like sending back User Roles to the user as they authenticate.
I am by no means an expert though and I am still learning this product myself. But hopefully this will help get your pointed in the right direction. These are just some of the steps we took to get going.
Cheers
