[squid-users] Squid 3.5.12

2016-02-23 Thread Nando Mendonca 
Hi All,

I had Squid 3.5.12 running  with ldap authentication on port 389 great. I now 
need  to run squid on port 636. With my same configuation i'm unable to get 
squid working.

What compile options do i need? I was using basic_ldap_auth do i need to use 
something else?

I can communicate from the Squid server to the ldap server on port 636 using 
ldapsearch.

Thanks!

[squid-users] Squid configuration help

2016-02-16 Thread nando mendonca 
Hi All,

Currently i have Squid 3.5.12 setup with LDAP Authentication and with
groups. If a certain user is apart of a certain group they can access sites
that are listed in the allowed list, otherwise access is denied for all
other sites.

I have a new requirement to allow all LDAP authenticated users access to
all sites, but then deny certain sites to certain groups.

Can anyone please help me with this new requirement?

[squid-users] squid 3.1 ldap authentication

2015-10-07 Thread nando mendonca 
Hi,

I have squid 3.1 installed using ldap authentication. When i access a
browser i enter my ldap credentials and it works fine. I’m able to browse
all sites without any issues.


Is there a way to use ldap groups to allow certain groups access to a few
sites on the internet and then pretty much block everything else?


I’m able to restrict access to only a couple of sites and block everything
else without using ldap group authentication, was just hoping this can be
done with ldap group authentication.


Thanks,
Nando
