I would like to find out is there anyone facing any problem when implementing PEAP using XP clients with ACS 3.3 and integrate with Microsoft AD to manage user database.
I have used ACS to generate self certificate and copy the .cer file and install it on client so that it is a Trusted Root CA inside the Xp client.
I have certain clients can be authenticated when Validate Server Certificate checkbox are checked. For other clients I need to uncheck the Validate Server Certificate checkbox, then they are authenticated. All are XP clients. There is incosistency in the configuration. WHat can I do next? Can anyone share any solution with me?
