[Help-gnu-radius] Unable to use Crypt-Local

[Rahim Pirbhai]

Hello,
I am trying to use Local Encrypted authentication. However, when I 
attempt to authenticate via radauth or via my radius client, 
authentication fails:

May 19 12:14:35 Auth.notice: (Access-Request local 79 "rahim"): Login 
incorrect [rahim/abc123]

"users" file:
-----------
rahim Auth-Type = Crypt-Local,
               Password = "e99a18c428cb38d5f260853678922e03"
       Service-Type = Framed-User,
               Framed-Protocol = PPP

radauth:

Authentication failed.
Access denied

I used an MD5 hash utility online to encrypt the password.
Can you please tell me what might be wrong?

Thanks,
Rahim
