Hello,
Thank you for posting question on Microsoft Windows Forum.
Based on your query of Windows 11 users being required to manually navigate to network settings and click "Sign on" to authenticate for network access using EAP-TEAP, despite having the correct Group Policy settings that work for Windows 10 (which only prompts for a PIN) and expectation to eliminate the manual step and have Windows 11 automatically prompt for the PIN.
The differences between Windows 10 and 11 behavior suggest that there might be a change in how network authentication is handled post-login. You can try the following suggestions for this issue.
**1.**Single Sign-On (SSO) Configuration
- Adjust Single Sign-On (SSO) Timing:
- Current Setting: "Perform immediately before User logon"
- Change to: "Perform immediately after User logon"
- This might better suit the scenario where the user is already logged in and the network authentication can use the user's credentials (smart card) without requiring manual sign-in.
2.Enable "Maximize Compatibility" for SSO:
- Check the box for "Maximize compatibility for Single Sign On" in the same Advanced Settings menu.
**3.**Check for Windows Updates:
- Ensure that the Windows 11 devices are fully updated, especially with the latest cumulative updates which might address known issues with EAP-TEAP.
**4.**Temporarily Disable Credential Guard for (testing purpose):
- To test if Credential Guard is the issue, you can disable it temporarily by setting the Group Policy by navigating to following path.
- Computer Configuration > Administrative Templates > System > Device Guard > Turn On Virtualization Based Security > Disabled.
- Reboot and test.
**5.**Using Event Viewer for Diagnostics:
- Check the Event Viewer on the Windows 11 machine for any related errors in:
- Applications and Services Logs > Microsoft > Windows > Wired-AutoConfig > Operational
- Applications and Services Logs > Microsoft > Windows > WLAN-AutoConfig > Operational
- Look for events that indicate why the authentication is failing to trigger automatic.
You can refer to below article for more information about what changes in Windows 11 for EAP.
Hope the above information is helpful!
