I am currently trying to set up a WLAN using EAP-TLS for authentication. I am using Cisco ACS 4.1 authenticationg users with AD.
At the moment I seem to have no problem with Domain users, they log on through the wired network, obtain a certificate and from then on will authenticate and join the WLAN set up.
However when ever a Domain admin tries this it fails. I get the following message in the ACS failure log; "External user not found".
Any help would be greatfully recieved.
PLease feel free to ask questioned as i know this is a little vauge.
