Hi

 

I’m using FreeRadius 2.1.12 wih mschap and  ntlm_auth external execution module as follows:

 

        ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}"

 

I want to run ntlm_auth from command line so enabled auth_log  to get challenge and response:

 

        MS-CHAP-Challenge = 0x8f89ccd88332fd05b75cd39a9d08c296

        MS-CHAP2-Response = 0x0100a6a4eb77926c3f1e7f78254b08f720a800000000000000002a0c1f094749304c3d11cdc8376cbe4373de0d61c2823011

 

I’m running ntlm_auth from command line with those parameters:

 

/usr/bin/ntlm_auth --request-nt-key –username=kimia-mo  --challenge=8f89ccd88332fd05b75cd39a9d08c296  --nt-response=0100a6a4eb77926c3f1e7f78254b08f720a800000000000000002a0c1f094749304c3d11cdc8376cbe4373de0d61c2823011

 

 

And Got error:

 

hex decode of 8f89ccd88332fd05b75cd39a9d08c296 failed! (only got 16 bytes)

 

with radius –X , I saw that the challenge and response is differ from that I got in auth_log in same session. So if I run ntlm_auth with new values, it’s OK!  what’s wrong?
