but i guess it does something more than just authentication because i 
can pass the mschap challenge and the nt-response to my script when 
configuring the mschap module like this:

ntlm_auth = "/usr/local/bin/otpme-auth -l verify_ntlm 
'%{%{Stripped-User-Name}:-%{%{User-Name}:-None}}' 
'%{%{mschap:Challenge}:-00}' '%{%{mschap:NT-Response}:-00}' 
'%{NAS-Identifier}' '%{Client-IP-Address}'"

but from inside the rlm_python module i cannot access this two 
attributes.

it would be great to have access to them from within rlm_python....
