I have smart switch that supports 802.1x authentication with EPA per port. Is it possible to make it work with UM? If yes, than how? Thank you.

Ok. I've made it to "work". "Work" in quotes because in UM logs I have messages "authorisation success", but Windows client 802.1x (Windows XP SP3) reports that authentication failed. Tried PEAP and md5 check. Any solutions?
