802.1X authentication fails after restricting AD user logon to specific computers

802.1X authentication fails after restricting AD user logon to specific computers

Hi everyone,

I would like to ask if anyone has experienced a similar issue while working with ExtremeControl.

Our customer has the following environment:

  • 2 × ExtremeControl Engines
  • 1 × ExtremeCloud IQ Site Engine
  • 2 × Wireless LAN Controllers (WLCs)
  • Active Directory used as the authentication source
  • 802.1X authentication (PEAP/MSCHAPv2)
  • Dynamic VLAN assignment after successful authentication

The authentication workflow is the following:

Client

│ Connects to SSID (802.1X)

Wireless AP


WLC


ExtremeControl (ACE)

│ RADIUS Authentication

Active Directory

│ User authenticated

ExtremeControl returns VLAN


Endpoint receives VLAN and network access

The issue

At the customer's request, they modified the user's Active Directory account.

In:

Active Directory Users and Computers
→ User Properties
Account
Log On To...

Instead of allowing the user to log on to all computers, they restricted the account to only one specific computer.

After applying this change, the user is no longer able to authenticate through the 802.1X wireless SSID.

My questions

  • Has anyone encountered this behavior before?
  • Does ExtremeControl (or Windows NPS/LDAP authentication) validate the Log On To restriction during 802.1X authentication?
  • Is this expected behavior from Active Directory?
  • Is there any recommended approach if the customer wants to restrict interactive Windows logons without affecting wireless 802.1X authentication?

Any insights or best practices would be greatly appreciated.

I appreciate the detailed troubleshooting steps. Problems involving AD policies and 802.1X can be difficult to diagnose, so it's great to have a clear explanation of what was happening. Paylocity
