I currently am running a primary/backup ACS server to authenticate my wireless users. PEAP is the authentication method. I generated a self-sign certificate on both the primary and backup ACS servers and primary works fine. When I stop services on the primary I see users fail to the backup but on my test machine which has the secondary certificate loaded it will not authenticate.
I submitted a package.cab file to TAC and they couldn't even see my machine hit the ACS server.
Has anyone seen this issue?
