Squid + Dansguardian + AD Pass Through
-
Hey all,
This is my first post so please be gentle with me! I'm sort of a noob with pfsense though I have converted my company from a Cisco 1800 router to a pfsense box which is running happily.
I've set up a new box and am currently testing Squid + Dansguardian as a company proxy server (with content filtering) and have Squid authenticating with our Active Directory infrastructure. The system prompts for a user name and password and everything works ok. I was wondering if there was a way to support pass-through authentication so that the system does not prompt for credentials? I've had a look but can't seem to find any decent guides. Can anyone help?
Thanks in advance!

tupoar,
You will need to install samba and configure ntlm auth on squid to get this working.
There is on post at portuguese forum(google translate it) that can help you:

I have finally managed to get through the guide and join the pfsense box to the domain.
However, the Proxy Server service will not start. The system log says

what you get if you try to run the ntlmauthenticator cmd line from console?
It's crashing, so it may help you identifying why.

Hi Marcello,
I have managed to get past that problem but face more issues, too many to post.
I've decided to give up at the moment as I am very frustrated and am liable to do something silly! I have followed every possible posting on the forum and nothing seems to work.
is it possible to provide a step-by-step guide (in English) to getting this working??
For now, I am going to have a lie down in a dark room…

Hey Marcello,
The DNS has already been set to Active Directory DNS. I can also confirm that the box can ping the domain controllers by name.

did you checked smb.conf?
winbind should work with this config. -
We have a break through!!
I checked the samba.log and the winbindd.log and they indicated that the /var/log/smaba directory was missing. I have recreated the folder and everything seems to work!! Except…
The Proxy Server service still fails to start....
