Hi,
I reaaly need help.
I am trying to set a Squid cache but I had no success for days.
I have already tried a lot of settings, but couldn't get what I desire.
I get an Access Denied or an Forward denied.
I would like to know if somebody can help me.
What do I want and what do I have?
I have three groups of users: direc, func, aluno. ( Will be more )
Each group of users have a group at my LDAP, with the corresponding
users inside. All users are in the ldap. ldap_auth and ldap_group are
working, because I could get the right answers from LDAP.
For each group of users I have two files with forbidden and allowed
sites, like this: ( to use with url_regex )
-porn_direc.txt --> forbidden sites for group direc. ( forbidden )
-noporn_direc.txt --> exceptions sites for group direc.( allowed )
I already have a porn.txt and noporn.txt, for generic uses.
I have a set of different networks that must use my proxy.
Like this:
-our_networks src 192.168.13.0/24 192.168.15.0/24
-coord src 192.168.17.0/24
I want to authenticate everybody from coord, but not for our_networks.
Everybody from our_networks cannot access porn.txt but can access
noporn.txt. They must not be authenticated or checked with
ldap_group.
Everybody from coord must be authenticated with ldap_auth, checked
with ldap_group and respect porn_group.txt and noporn_group.txt at
the same time. I mean, all conditions must be respected.
I am using squid-2.5.STABLE9, with all patches available.
Following is the only setting I got working, but not solve my problem
and have a problem when the request uses https. ( no authentication )
Please, if somebody have some setting that works like this, help me.
Thank you for your attention and forgive for my bad english.
