NTLM Auth Problem

[Ali Majdzadeh]

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?
