For those who are wanting Squid to do NTLM authentication (transparent in IE) against an Active Directory server (using Winbind), I've release a Walkthrough that may be of interest. Find out about it here: http://itmanagers.net/article-4--0-0.html Hopefully Squid's FAQ will soon include details of using Samba 3's ntlm_auth as well as the wb_ntlmauth helper that worked for Samba 2.x but in the meantime hopefully this walkthrough will help some.. (This is dedicated to those that, like me, upgraded to Samba 3 and found that the wb_ntlmauth helper no longer worked... doh!) Cheers to the Samba Team for all the hard work!! -- Daniel Palmer IT Managers.net - The Support Group http://itmanagers.net
