Authentication + IP checking

Hello to everyone on the list!

I'm having some trouble trying to solve this
problem... I have got authentication working in Squid
pretty well (with the proxy_auth ACL stuff). What I am
desperately trying to do is limit the users to login
ONLY from their machines (only on their IP adresses).

There are only 10 IP addresses allowed to surf the web
today, using Squid as the proxy server (the rest of
the network can't access port 3128; the firewall rules
block it). What I am trying to do is avoid that EVEN
people who are allowed to surf the web do it outside
their PCs. Kinda "lock" the username + password to the
machine's IP adresses.

For example: today, say, John has a username and
password. His IP address in our network is 10.1.1.130.
Mary also has her username and her password and her IP
address is 10.1.1.131. I don't want her to be able to
use her username/password in John's machine and
vice-versa. I know this sounds paranoid and it is ;-)
but I just receive orders anyway :)

If someone has any helpful trick, I'd be REALLY
thankful!!
