Hello,
I have an Internet Information Server 4.0 that operates with Basic Clear authentication.
There is a part of the Web site that requires password in order to access the information.
The problem is that if I enable NTLM Challenge response on the Web Server the client (from outside facility) reports that he sees the following message.
“HTTP Error 401
401.3 Unauthorized: Unauthorized due to ACL on resource
This error indicates that the credentials passed by the client do nothave
access to the particular resource on the server. This resource could be
either the page or file listed in the address line of the client, or it
could be another file on the server that is needed to process the file
listed on the address line of the client.
Please make a note of the entire address you were trying to access and then
contact the Web server’s administrator to verify that you have permission to
access the requested resource.”
If I enable basic clear text (disable challenge response) it works without problems and the user can access the restricted information.
What cause this problem?
Thanks in advance.
