------------------------------------
Summary: Issues with NTLM authentication in GetHttp and InvokeHttp
processors
Key: NIFI-3096
URL: https://issues.apache.org/jira/browse/NIFI-3096
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Michael Kalika
GetHttp and InvokeHttp do not support HTTP endpoints protected with NTLM
authentication. This functionality is needed for working with services and APIs
hosted in Windows systems.
Here's a log with error:
