I am trying to use the Webpage Retriever node to extract a page from an internal IIS server. From a browser, access to the site is authenticated automatically. I have been unable to authenticate using the Webpage Retriever node using basic, digest, and NTLM (Labs) methods. I have enabled the Kerberos config in KNIME Desktop and have an active ticket. However, it does not seem the nodes leverage Kerberos as I still get 401 errors. Looking for suggestions on next steps I can take to resolve.
Thanks Phillip. I understand. Are there other ways of using the HTTP Retriever to access IIS servers using native Windows authentication. This is a pretty common scenario in many enterprises.
admittedly I lack the background knowledge about MS products. Are there any other authentication mechanisms supported? Do you have some technical documents or examples which you could share here to see?
