Hello I am running freeradius-2.17 on CentOS-5.5 box with mysql-5.0.77 as backend and daloradius-0.9-8 as the web management. I have successfully configured an tested EAP-MD5, PEAP and PAP authentication using windows 7 as supplicant with wired 802.1x authentication (no certificates used) and NAS as a Huawei Switch (Quidway S5600 Series) and seems to be working fine. Now my issues are: in my networks there are various kinds of OS running for supplicants. To name a few are Windows XP (SP2, SP3), Windows Vista, Windows 7, Fedora, CentOS, Ubuntu and Mac OS X. I have to configure AAA applicants systems in such a way all this systems are supported. Can someone help me suggest or have any idea/experience on this. What could be the best authentiation method that I can use so that all this supplicants using different OS are supported. Also I use wired connection as well as wireless connection in the network. Does anybody throw some light on this matter? Thanks in Advance -- homyang (aka puran)
