Squid on Linux authenticating to two different Windows Active Directory groups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

I've got Squid on a Linux (Debian 3.1) box running beautifully and
authenticating users to a Windows Active Directory.
The bits from squid.conf that I think matter for this discussion looked like
this ...

||auth_param ntlm program
/usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
||auth_param basic program
/usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic

Then later on I have ...

||acl ADuser proxy_auth REQUIRED

and then

||http_access deny !ADuser
||http_access allow all

Ok, so this means only authenticated users can use the proxy and access.log
has their Windows usernames

I can further change auth_param to allow only members of one certian Active
Directory Group

||auth_param ntlm program
/usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp --require-membership-
of=XXX_DOMAIN\\ADgroup1 --domain=xxx_domain
||auth_param basic program
/usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic --require-membership-of
=XXX_DOMAIN\\ADgroup1 --domain=xxx_domain

||acl ADgroup1 proxy_auth REQUIRED

Although the above works great, what I really want is the following

1 - Authenticate all users (need to see those usernames in access.log)
2 - Allow all users access to some sites (freesites)
3 - Allow Active Directory Group 1 access only to freesites, and a few more
(othersites)
4 - Allow Active Directory Group 2 access to all other sites

Ok, so I can

add freesites

||acl freesites dst_domain .cnn.com
||acl freesites dst_domain .bbc.co.uk

add othersites

||acl othersites dst_domain .yahoo.com
||acl othersites dst_domain .hotmail.com

and setup of acl hierarchy would be something as follows:

||http_access allow freesites
||http_access deny !ADgroup1 !ADgroup2
||http_access allow othersites
||http_access deny !ADgroup2
||http_access allow all

Problem I have is how to setup the acl to get the different ADgroups?  Do I
need two auth_params? Is that possible and what would the syntax be?

Thanks

Yours

Roy
