I was wondering if I use allow_ntlm=True for OnPremise SharePoint. Each query will contains 3 HTTP transacitions?
In each query, the first http response indicates www-authenticate:NTLM, the second transaction finish NTLMSSP_NEGOTIATE, the third transaction does the actual work about querying to SharePoint.
Each query has to finish these three steps?
I'm not familiar with NTLM and SharePoint. However, in my opinion, if I finished NTLM negotiation, I should get kind of token. SharePoint should keep the authentication result state for me. Each time I'm sending a query to sharepoint, I just need to take the "token" thing.
