Can Squid do what Blue Coat BCAAA does with transparent silent NTLM auth

[Elvar <elvar@xxxxxxxxx>]

Hello,

For several years now I've used Squid with Winbind to silently 
authenticate users to Active Directory which has worked wonderfully. The 
one thing I've always had to do though is configure the user proxy 
settings to manually point to the proxy in order for it to silently 
authenticate. If I try a transparent proxy configuration without 
specifying manual proxy settings in the browser the silent 
authentication does not work.

According to some friends who use a product called Blue Coat SG there is 
an agent called BCAAA which allows you to have the proxy configured in a 
transparent manner, not specify manual settings in the users browsers, 
and still get silent NTLM authentication. Is there any way to do this in 
Squid that I'm just not aware of?


Kind regards,
Elvar
