Question

Refer to the exhibits. A company has added a new user group. Users in the group try to connect to the WLAN and receive errors that the connection has no Internet access. The users cannot reach any resources. The first exhibit shows the record for one of the users who cannot connect. The second exhibit shows the role to which the AOS device assigned the user's client. What is a likely problem?

Explanation

The scenario involves an AOS-8 Mobility Controller (MC) with a WLAN where a new user group has been added. Users in this group cannot connect to the WLAN, receiving errors indicating no Internet access and inability to reach resources. Exhibit 1 shows the ClearPass Policy Manager (CPPM) Access Tracker record for one user: CPPM sends an Access-Accept with the VSA Radius:Aruba:Aruba-User-Role user_group4. The endpoint is classified as "Known," but the user cannot access resources. Exhibit 2 (not provided but described) shows that the AOS device (MC) assigned the user's client to the "denyall" role, which likely denies all access, explaining the lack of Internet and resource access. CPPM sends the Aruba-User-Role VSA with the value "user_group4," indicating that the user should be assigned to the "user_group4" role on the MC. However, the MC assigns the client to the "denyall" role, which typically denies all traffic, resulting in no Internet or resource access. The issue lies in why the MC did not apply the "user_group4" role sent by CPPM.
