I know that the Portal Server Gateway doesn't support NTLM
We have some intranet-sites which we try to access via SRA.
So we enabled both "Basic Authentication" and "NTLM", but the
gateway gets a "HTTP 401.2" - "not authorized".
Instead, it should use the "Basic Authentication" method (like browsers does).
It is not possible to disable the "NTLM"-method on the webserver,
because it is already used for intranet access.
(I cross-post this in Portal Server 3 and Portal Server 6, because the
question applies to both versions).
