How to configure EAP Identity in 1.1.3

[Govardhana K N]

Hi,

I was trying to configure FreeRadius server with EAP authentication. AS
mentioned in "eap.conf", I didn't change the Auth-Type, but I was sending a
EAP message, and Message-Authenticator attributes in Access-Request. When i
tried sending an Access-Request with EAP-Message, I got the following error
"rlm_eap: Identity Unknown, authentication failed".

How to configure the Identity for EAP?
