Hi, I want to create an authenticator in perl - I don't want people to have to manually type usernames and passwords, I just hope to grab their usernames from the NTLM and trust that they haven't installed a browser that can't supply the credentials automatically like IE. There is a number of different domains too so I want to be able to accept them all.. Is there a way to get IE to send the username that squid passes onto an external authentication module? The authenticator will permit any password - I just want it to capture the username. The idea is that the proxy stays transparent but I can still see the usernames in the log files if I need to. I'd really appreciate any tips. Thanks, Adrian.
