So I'm working on just getting basic radius authentication working with Juniper's Junos Space product, where it has 3 protocol choices, PAP, CHAP, and MS-CHAPv2. I've pointed the box at ClearPass for authentication and Space indicates that is has a valid connection, but when I try to authenticate (using either local or AD accounts), I get errors.
If I'm using PAP or MS-CHAPv2, the error is "Cannot select appropriate authentication method" (the logs state "ERROR RadiusServer.Radius - rlm_auth_check: Auth-Type not set or authentication methods have not been configured. Rejecting it."), and if I'm using CHAP, the error is "CHAP: Clear text password not available"
Is the above an indication that Junos Space may not be passing the "Auth-Type" field in it's radius request?
I'm working with Juniper to get a copy of the raw radius request to look into what's going on but are there any thoughts on the Aruba side on what's going on here?
