I have contacted SAS tech support and they have pointed me to this SAS notes. This doesnt help. Please advise.

Usage Note 15692: URL filename engine only supports BASIC authentication on web server

When you attempt to read web server data using the URL filename engine, the following error message might appear

ERROR: Unauthorized to retrieve URL

and with the DEBUG option

NOTE: <<< HTTP/1.1 401 Unauthorized

even when supplying valid credentials with the USER and PASS options. Using the DEBUG option on the filename might show the cause to be the web server's use of an authentication method other than BASIC. Notice
the DEBUG line below:

NOTE: <<< WWW-Authenticate: NTLM

The URL engine will not properly authenticate to a web server unless it uses the BASIC authentication protocol.
