Squid doesn't care (at the moment); its just passed credentials. Normally you'd actually prevent an entire computer from connecting to the network. Enterprises do this via a variety of means, including stuff like 802.1x. Drop them in a seperate VLAN if you don't recognise the computer and disallow that VLAN access to the proxy (and other resources.)
