Cool. Lets wait and see if that actually happens however :]

I can understand your viewpoint, but the cygwin port of squid needs to
be able to be used on all platforms cygwin supports. Which includes
win95. And personally, I intend to never use Windows XP unless MS change
their "activation" system. You can add NT only functionality, but only
as a compile-time option via the configure script.

There should be no issues - Kinkie is running NTLM on several thousand
users with multiple domains, and there are no problems related to the
domain\username. The access log and all the username compare and string
splitting functions support domaun\username syntax. Their is one
possible hole: the sending of the username password to the basic
authenticator - if you see a bug there, either patch it (see
src/auth/auth_basic.c) and mail me a patch, or just tell me and I'll
generate a fix. (Again - this sort of bug-fix should go nearly direct
into HEAD, or for auth stuff potentially into auth_rewrite and then
HEAD).
