Re: [squid-users] SQUID + FIREFOX + ACTIVE DIRECTORY

Always forget to hit the 'reply to all' instead of the 'reply'.. sorry.. below is what I sent Chris:

Below is for w2k3 AD and Ubuntu 6.06.1:

auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 15
auth_param ntlm max_challenge_reuses 0
auth_param ntlm max_challenge_lifetime 2 minutes
#auth_param ntlm use_ntlm_negotiate off
auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
auth_param basic casesensitive off
acl NTLMUsers proxy_auth REQUIRED
acl our_networks src 192.168.0.0/16
http_access allow all NTLMUsers
http_access allow our_networks

Here is our current setup (w2k8 and Ubuntu 8.04.1):

auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 15
auth_param ntlm keep_alive on
acl our_networks src 192.168.0.0/16
acl NTLMUsers proxy_auth REQUIRED
external_acl_type ntgroup %LOGIN /usr/lib/squid/wbinfo_group.pl
acl NOINTERNET external ntgroup no-internet
http_access deny NOINTERNET
http_access allow all NTLMUsers
http_access allow our_networks
http_access allow localhost

We
have a group policy do the IE browser, but with Firefox, we have to set
it manually. Once it is set, there is no prompt... I use SARG to get
the results.. Been doing it for almost three years.. I would get
evangelical on people using iPrism/Barracuda/Websense.. but now I
figure I will just let them spend the money.. ;-)

> I am totally confused by this statement?.. as I have 300 people using firefox right now.. using Ubuntu 6.06, Samba3, Squid2.. and not a single one gets a user/pass prompt? I am not using it as a transparent proxy, it is listed in firefox under proxy settings (8080 because it goes to DG first.. but I have tested just Squid at 3128 and it works as well).. and I haven't touched anything else in firefox

I'd be very interested in knowing what is different about your setup.
I have fought this problem for several years now.
