Our internal testing asserted that this functionality worked against a Kerberos server. We got the error you received when testing python3.6.1 against an NTLM server, which we thought was related to <A href="https://sourceforge.net/p/pywin32/bugs/748/">a pywin32 bug</A> introduced in python3.6.1. It's possible that this error is something else, however, that affects more versions of python.</P></BODY></HTML> Fri, 09 Feb 2018 19:22:10 GMT https://community.esri.com/t5/arcgis-api-for-python-questions/connecting-to-non-federated-iwa-enabled-arcgis/m-p/775163#M888 Anonymous User 2018-02-09T19:22:10Z Re: Connecting to Non-Federated IWA enabled ArcGIS Server with Python API https://community.esri.com/t5/arcgis-api-for-python-questions/connecting-to-non-federated-iwa-enabled-arcgis/m-p/775164#M889 <HTML><HEAD></HEAD><BODY><P>Hi, we are also receiving the above issue. Unfortunately Kerberos is not an option.
