I hate to sound like a pedantic ass. But, if you read the document I had linked to my response at Apache::AuthenNTML you'll see that it says:
The purpose of this module is to perform a user authentication via Mircosofts NTLM protocol. This protocol is supported by all versions of the Internet Explorer and is mainly usefull for intranets. Depending on your preferences setting IE will supply your windows logon credentials to the web server when the server asks for NTLM authentication. This saves the user to type in his/her password again.What really seems to get my goat is that you asked this question before at NT login to authenticate web user and you got basically the same answer I gave you from valdez. Go to your network, set up a few of the solutions that have been suggested to you, try them out, get back to us with error messages or success stories.
