Hi All, I was able to get authenticated using radius server for EAP-TTLS/EAP-MD5, by having following configuration Modified eap.conf --------------------------------------------- eap { default_eap_type=ttls ..... ttls { default_eap_type=md5 ..... } } Modified users file as below -------------------------------------------------------------------- raghu User-Password == "whatever" Modified clients.conf as ------------------------------------------------ 10.89.49.1 { secret=raghu123456 shortname=3Com } Can anybody tell me how to support, EAP-TTLS, CHAP/PAP... I mean second level protocol inside TTLS should be chap/pap/mschap/mschapv2. -- Regards & Thanks Raghavendra. S
