Hello , I want to install freeradius server for the authentic wifi users , whose database is stored in ldap server ..Users who will use the wifi are mostly windows xp /vista users. what i have tried: (1) Install openssl by apt-get install command ... (Also By the source code by the commands ./configure make make make install) (2) installed freeradius-1.1.7 ./configure make make install (3) used default configuration and added one entry in the users file .. (Also tried for installing with apt-get install freeradius freeradius-ldap freeradius-eappeap .. ) It worked well with radtest from localhost .. But when i try from laptop ..it does not work .. After That i tried to configure eap type peap since i came to know that windows xp /vista support EAP/PEAP for wifi authentication . with this configuration also radtest works well ...but from laptop it does not work (4) I receive the following request from AP Message-Authenticator = 0x3f459af06e42a2a0b7cf9c1d80092e31 Service-Type = Framed-User User-Name = "testap" Framed-MTU = 1488 Called-Station-Id = "00-15-E9-C9-F3-80:MNIT-DC-AP" Calling-Station-Id = "00-16-6F-7C-DB-2D" NAS-Identifier = "D-link Corp. Access Point" NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 54Mbps 802.11g" EAP-Message = 0x0200000b01746573746170 NAS-IP-Address = 172.16.1.80 NAS-Port = 1 NAS-Port-Id = "STA port # 1" I want to ask you that how radius server with get authentic the user since it is not getting user password or hashed password ..?? (4) I have tried all the above process for the freearadius-2.1.4 also , (When i try to install freeradius-2.1.4 it does not include eap/peap even i have installed openssl previously ... No problem with freeradius-1.1.7) I have tried all installation on debian/ubuntu/deepofix. I want to ask .. Is this compulsory to configure EAP/PEAP since our end users would have windows xp/ vista ..?? what will be basic configuration ..?? I am sorry .. i am not posting any debug output here .. reason is -- i have been posted those already , got solutions for that but still i am not getting things working.. probably i got things wrong hence i am posting all things which i need .. Please give your views on what i have understood wrong ..!! and what should i do ..?? Please provide me the steps for this scenario ...!!!
