Hi, I've built a FR-2.1.3 (with rlm ldap) on OpenBSD, with credentials on a OpenLDAP (2.3.30-5+etch3), using EAP-TTLS. Everything, 's working fine with Iphone,Linux &MacOS. But with Windows (XP, Vista & 7), i'm unable to get the SecureW2 (v3.3.3.) client connecting. 1. Downloaded locally both the CA & Radius .der certificates 2. Installed both of them of local computer. 3. Add both (and also tried only radius cert, or no cert at all) certs to SecureW2. But Always got : "Received an invalid server certificate, please verify your certificate configuration" response from the software. All the steps (in french) : http://www.openbsd-edu.net/index.php/FreeRadius Found almost nothing usable either on the Securew2 website or on the goggled links... If anyone had an idea..
