Keberos Error: Minor code may provide more information (No key table entry found for HTTP/

Question

Our standard Keberos configuration does not work with Windows Server 2019 but no issue with Windows 2012. Is there any new settings/requirements on Windows 2019?

Browser error: Keberos configuration is not valid. Failed to retrieve SPNEGO credentials: Unspecified GSS failure. Minor code may provide more information (No key table entry found for HTTP/******@MYDOMAIN.org)

Answer 1

Hello there,

The error message indicates that there is an issue with the SPN service account's ability to validate itself against the Generic Security Service (GSS) API.

This might be due to the mismatch of encryption types between clients and the KDC server.
