Hi Santiago,

     I would suggest you to first try with radtest to see ntlm_auth BIND AS USER is working or not.

Have a User entry in Users file with Auth-Type := ntlm_auth
Add ntlm_auth in Authenticate section of default and inner-tunnel files in /sites-enabled directory.

Then if radtest returns NT Success Ok or ntlm_auth is being done by Server.
Then Try for RADIUS requests from actual NAS.

I have done this way as of now to check ntlm_auth Bind.

The Experts can show you more light in your problem.

Regards,
SYED

Hi all
I follow the instructions of Alan :

<http://deployingradius.com/documents/configuration/active_directory.html>

to authenticate ntlm_auth with radius but appers the following message:

" WARNING: Unknown value specified for Auth-Type.  Cannot perform requested action.
auth: Failed to validate the user."

what is wrong?

Please help.
Santiago
