Where does ISS come into the picture?

Looks good to me.

Hmm.. confused browser.

What does "log_mime_hdrs on" give in the initial 407 response headers from
the proxy?

The user name logged in basic authentication is the username entered in
the browser. This may be with or without the NT domain when using a NT
domain backend.

Ok. So wbinfo_group.pl either does not like the username or the group
name. Your testing suggest that it does not like the domainless login
name.

Solution a): Enter the login using domain name in the browser.

Solution b): Teach wbinfo_group.pl how to handle "accuounts in the default
domain" where no domain name is specified in the login name.
