// in user name ?

Hi, I asked this in morning also, and am still looking for ana answer. My set up is very simple winxp,-> wireless router -> free radius PEAP -MSCHPv2 .. How am I supposed to configure free radius for clients with "//" in their user name ? like by default it will send domainname//user-name are // allowed ? if I just add user names like this, PEAP is failing .. Anyone please guide this new bie. Cheers, Alfred
