Help(1.1.3): Access-Reject is sent by server for EAP-MD5 challenge response

[Govardhana K N]

Hi,

I am trying to send an Access-Request with EAP-Identity response. The
Request was successful and Server sent an Access-Challenge in response (MD5
challenge), the response to this challenge is failing (receiving
Access-Reject from Server), the Error message was "rlm_eap_md5:
User-Password is required for EAP-MD5 authentication". I have the
User-Password attribute in Access-Request. Below is the Access-Request
packet attributes,

--------------------------------------------------------------------------------
User-Name = jrc
User-Password = jrc
Nas-identifier = jrcnas
Nas-Ip-Address = 10.10.10.10
Nas-Port = 20
Nas-Port-Type = 15
CUI = 0
Service-Type = Framed-User
Framed-MTU = 1400
Calling-Station-Id = 1:1:1:1:1:1
NSP-Id = nap
BS-ID = TestBS
EAP-Code = Response
EAP-Id = 210
EAP-Type-Identity = "jrc"
EAP-MD5-Password = jrc
Message-Authenticator = 0x00
--------------------------------------------------------------------------------

am I doing any wrong here? Can Anybody help me how to solve this problem?
