Hello, OAC GINA is used in enabling network authentication to occur before the user is authenticated against the AD. This helps similar to the single sign on where the user is not required to enter login credentials twice. Generally when 802.1x is implemented for L2 authentication, the user is not allowed to send any traffic through the switch port before L2 authentication is performed. GINA captures the user credentials from windows logon dialog, delays the log on process on windows and uses the credentials to authenticate on the network. Once the Authentication is done, windows log on process occurs as usual. In this scenario, authentication is happening in two stages, 1- authenticating on the network 2 - authenticating to the domian. OAC GINA is a replacement of Windows GINA module, that helps Odyssey Client to perform network authentication using windows logon credentials. This requires the user to enter credentials only once while actually the authentication is happening 2 times. Hope this helps. Regards, Partha
