@ShareefKooliyodan0444 the endpoint has performed MAB and ISE has attempted to lookup the endpoint using Active Directory, which has no account for the MAC address, hence the error - ERROR_NO_SUCH_USER.

You may wish to check the configuration of the endpoint is configured with 802.1X correctly.

Also you may wish to review your ISE rules to not check AD for MAB connections, use the ISE Internal Endpoints database.
