It comes down to the fact that the authentication techniques I’m being presented with change depending on whether I use https://[hostname]/ServerAPI/ServerCommandService.asmx or https://[hostname]/ManagementServer/ServerCommandService.asmx to do a login.
The header of the response to my posting a login request is:
HTTP/1.1 401 Unauthorized
Content-Type: text/html
Server: Microsoft-IIS/10.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM <---- Missing for ManagementServer
X-Powered-By: ASP.NET
X-Frame-Options: SAMEORIGIN
Date: Sat, 22 May 2021 11:21:47 GMT
Content-Length: 1293
When using the URL with the path that contains “ManagementServer” I don’t get the option for NTLM and it fails when I then go on to attempt to authenticate with it.
I’m not sure how a misconfiguration could affect one endpoint and not the other.
Any help would be appreciated.
Thanks
Jim
