What is needed to resolve this issue?

You configured" a bridgedmode SSID with WPA3-Enterprise and EAP-TLS security. When you connect an Active Directory joined client that has valid client certificates.

ClearPass shows the following error.

What is needed to resolve this issue?
A . Enable authorization in your Authentication Method.
B . Recreate the SSID m tunneled mode.
C . Modify your ACX-AD authentication source to include the UPN in the search.
D . Configure ClearPass to trust the client certificate.

Answer: C

Explanation:

The error message "User not found" indicates that the authentication source, in this case, Active Directory (AD), is not able to locate the user account based on the current search parameters. This often occurs when the User Principal Name (UPN) that the client is using to authenticate is not included in the search parameters of the AD authentication source within ClearPass. By modifying the AD authentication source to include the UPN in the search, ClearPass will be able to correctly locate the user account and proceed with the authentication using the valid client certificates.
