[squid-users] RE : [squid-users] Transparent proxy, authenticacion,differentscenarios

Using logon script, you can reach your purpose transparently.

The logon script adds correct registry keys to support proxy config (example)
        Using Regdmp.exe (to manipulate Registry DB from command script - you can find it everywhere)
        Regdmp.exe "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer "http=toto:8080;ftp=toto:3128;socks=toto:3128;https=toto:3128"

Then you are not any more in transparent proxy mode, and you can use NTLM automated authentication.

Semi-automatical: WPAD, if the browser has WPAD enabled. WPAD can set
the proxy configuration via DHCP or DNS.

Automatical: Via a domain logon script if your users are Windows users
logging on to your domain.

Forced: Firewall port 80, deny your users direct access. This can also
display a web page explaining to the user that they need to configure
the proxy settings in the browser and how (just use the same methods as
for transparent interception, but instead of sending the traffic to
Squid, send it to a web server).

Most RPMs include ncsa_auth, but you should probably spend some minutes
and decide if NCSA auth is really what you want, or if you prefer to
integrate with a existing user directory such as LDAP / NT Domain /
Radius / NDS/ ....

For Squid-2.5 ncsa_auth is in libexec/. With a standard RPM install this
should be /usr/libexec/squid/
