The other network guy who I can work with told me he got it to work briefly on one device running 10.7.
He said somewhere in the keychain he pulled the computer name and password.
He says the authentication is device based, not user based.
Via Profile Manager all I can do is get the popup at login prompt to select the proper WiFi. Once I sign in (with cached credentials) under System Preferences it tries to connect to WiFi and fails quickly.
