I would like to know if it is anything around (command, lib, etc ) that,
given a username/password in my Linux box, check it against an NT PDC.

Maybe it will be more clear what I need, if I explain why I need it:

I'm setting up a Linux box whith squid 2.2.x and I want to only let browse
out valid users of certain NT domain. I plan to use the new "proxy
auth"
feature of squid, that consist in call an external programa passing it
user/pass and checking its output. I can make that program, but I need a
lib or so to do the authentication.


If I don't get any useful answer I will have no more remedy than doing 
some ugly thing using smbclient :) 


Thanks in advance
