REST API - Authentification issue when connecting via NTLM to swagger/json

[troggy]

Hi all,

I have currently problems with connecting via REST (POST) to a json query in swagger.

with desktop version as authentification scheme "current user" it is working without any problems, when moving to server (or also desktop) with Windows NTLM  and dedicated user, I only get authentification error.

Host is swagger with Kerberos auth server

Any ideas or where I could move on investigating?
