So, it looks like I need mod_setenvif, right? Could anybody write a

directive that would look at REMOTE_USER to see if there is a backslash

the

mod_authnz_ldap that mod_auth_sspi as it is included with Apache and is
well-supported.

The authentication/authorization modules don't read from the
REMOTE_USER environment variable.

Well, where are they getting their info? This is what I'm getting in the
error log:

[5028] auth_ldap authenticate: user WHQ_NT_DOMAIN\\ch017001 authentication
failed; URI /scpmanager/ [User not found][No Such Object]

Clearly domain\user is getting passed to the authn/authz modules from IE
somehow or another.

This is getting interesting. How indeed ?
Is there a way to trace the headers being sent back and forth during this authentication phase, at the Apache level ? We're talking IE as a browser here, so Firefox add-ons don't count.

If not, assuming that server has perl and mod_perl available, I could put together a quick access handler that does that.
(as mentioned before, I have a stake in a solution too).

In this case, Apache is running on Windows. Although it could be loaded, perl and mod_perl are not available at the moment. I'm beginning to think we're chasing our tails. IE is going to pass the credentials in NTLM format, I believe. Even if we got the username right, I'm thinking maybe the password won't be readable by mod_authn_ldap. I don't know.
