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

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 =

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

/usr/bin/ntlm_auth --request-nt-key –username=kimia-mo

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?
