Hi all, After many weeks with no results, It's time to find help ! Debian : 5.0 Freeradius : 3.0.4 (with openssl) Samba : 3.2.5 AD : Windows 2008 PEAP & MSCHAPV2 CISCO AP Here is the problem. We use MSCHAP V2 with PEAP for Windows and Linux Client, the problem is so strange. On HP laptops with Intel Proset wireless or IBM Thinpad with Thinkvantage tools the connection was successful. The same laptop with Windows zero config wireless client or Linux (Fedora, Debian) impossible ! No error on log debug, just an authentication silently failed. Yes certificates have Windows OID client/server (xpestensions) Any ideas ? Thanks in advance for your answers... Bernard. PS : No, I don't want to use MS Radius !! ____________________ Bernard Jaulin - ilem S.A. Administration systèmes * +41 (0)79 593 22 46 Route de la Galaise, 32 1228 Plan-Les-Ouates http://www.ilem.ch/
