Configure Squid You need to configure Squid for proxy authentication. If you have problems doing this, have a look at the FAQ . You can also specify different broadcast addresses etc. per domain. Note that you don't need an abbreviation for the first domain since omitting a domainname implies authenticating against the first domain. To debug authentication you can additionally use the -d option which will print debug information after each step, so you can determine which step is failing.
Suggestions are welcome too.
These are the items currently on my todo list. If you need another feature currently not available, just let me know. I will add it to this list and who knows, it might even get implemented. I used a shell script mainly to speedup development.
