Authentication system

[mredloft]

How do set up authentication system in my proxy server(squid installed from RHEL 4) in such a way that each user must be given a separate user name and password and each user must be able to change their own password afterwards. I tried once with NCSA_AUTH before but didnt find a way for users to change their respective password. My main objective is that each user must give their respective user name and password each time they are trying to access Internet through my proxy. How do i do this authentication sytem. I have RHEL 4 installed in the proxy server.

In ncsa, multiple users are possible.

See my post here : Squid NCSA Multiple users Authentication .

However there are various other options like squid2mysql which I remember provide a way so that user can change their password etc. on their own.

Also there is another mysql utility :
