I am attempting to configure ClearPass to authenticate users using AD credentials or certificates. If a user provides AD credentials or a certificate that's accepted, then I would like that user to be placed on the Network Access VLAN. If a user fails to authenticate, then I would like to put them on a Guest VLAN. The RADIUS connection between my aruba wireless controller and ClearPass appears to be working properly because AD users are permitted to use the wireless network. I used the Aruba 802.1X Wireless setup wizard under "Start Here" in ClearPass, but that just ends up authenticating all AD users. Is there a way to distinguish between AD users? I currently have a rule in the enforcement policy that states only an AD user that CONTAINS the string "exampleUser" should get the enforcement profile that permits them to use the network. Otherwise, I have a default enforcement profile called Guest VLAN, which is supposed to put them on VLAN 20. However, this setup doesn't appear to work the way that I intended. Everyone in the domain is just automatically admitted to use the network. Any idea what I am doing wrong?

You would use role mapping to map AD attributes to ClearPass (TIPS) roles. THen you can reference those roles in your enforcement policy to take action.
AD:Groups EQUAL IT-Staff TIPS role USER_IT
TIPS Role EQUALS USER_IT ROLE_IT

I just want to reiterate what you said to make sure I understand. You're saying that there isn't a way to authenticate AD users differently. If they exist in AD then they will be permitted to use the network.

Under roles I have a role mapping policy that has a condition that says if the AD name CONTAINS "exampleUser" then assign them the role of [Employee] and the default role is set to [Guest]. Under Enforcement I have two conditions. If Tips:Role equals [Employee] then the user is assigned the [Allow Access Profile]. However, if the Tips:Role equals [Guest] then they get the Guest VLAN profile, which is supposed to assign them to a dead VLAN 20. Everyone appears to just get the default role of [Guest] and the enforcement profile Guest VLAN. This happens even for "exampleUser". Do you know why this would be the case?

I found out the issue. It appears that if you're using the memberOf AD attribute on a user that is in two or more AD groups ClearPass only sees the highest priviledge AD group for that user. In other words, if you have exampleUser in Domain Users and Enterprise Admins and your Role Mapping Policy only deals with Domain Users then exampleUser wont get properly mapped until a Role Mapping Poliy deals with Enterprise Admins.
