"UnboundLocalError: local variable 'resp' referenced before assignment..." when Logging in to Portal for ArcGIS with the ArcGIS API for Python, when Extended Protection is on, in an IWA Environment.

Solução Provisória

• There's a setting in the IIS where one can turn the extended protection on or off. When this is off, one is able to login to the portal using the ArcGIS API for Python.
• Go to the portal's web adapter from IIS. Under the advanced settings of the Windows .Authentication. Turn "Extended Protection" Off (IIS > portal web adapter > double click Authentication > Windows Authentication).
• Turning it off allows one to login, but we are not certain of the implications of the same.
