Limitation of authenticating against AD

[Dennis Xu]

Thanks. Yes we have to configure FreeRadius server to use ntlm_auth. But  my problem is that our AD does not store passwords in NT hash format. They use SHA1 hash or crypt'd format.

Take a look at:

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

You need to configure your FreeRADIUS server to use ntlm_auth precisely 
because FreeRADIUS does not have access to the cleartext passwords of 
Active Directory users.
