If there is anything else I can post, please let me know.. I never even knew this was an issue.. The one client I started with a couple of years ago loves it, but they never would have let me go forward if some people had to log in and other didn't (half the users are on a TS farm.. and they all get IE).. so I can see how this would be an issue. ----- Original Message ---- From: Chris Nighswonger <cnighswonger@xxxxxxxxxxxxxxx> To: Amos Jeffries <squid3@xxxxxxxxxxxxx> Cc: nairb rotsak <ipguru99@xxxxxxxxx>; matlor <bfrobu@xxxxxx>; squid-users@xxxxxxxxxxxxxxx Sent: Saturday, November 1, 2008 4:47:24 PM Subject: Re: SQUID + FIREFOX + ACTIVE DIRECTORY On Sat, Nov 1, 2008 at 12:37 AM, Amos Jeffries <squid3@xxxxxxxxxxxxx> wrote: > Um, I'm not so sure the people having trouble are using the right helper. > > There is a thing calling itself 'ntlm_auth' bundled with squid 3.0 and > Squid-2 releases that is incapable of doing full NTLM for modern windows > domains. > > There is also something calling itself 'ntlm_auth' bundled with Samba, which > provides full working NTLM functionality. > > We have fixed this mixup in 3.1, but please check the helper you are using. > Please prefer to use the one by Samba. We're using the Samba flavor.

IE7 works fine on computers which are domain members. I'd still love to know what Nairb's config has that makes it work.
