Which version of squid are you running, default wheezy 3.1.x 
and you did add proxy user to the winbindd_priv group?  

I can suggest you recompile squid from jessie, its a pretty easy one. 
there are know problems with ntlm auth, in at the point of testing that one myself. 
scheduled for next week. 
I do already run 3.4.8 on my wheezy servers. 3.3.8 had some serious bugs.
