If Kerberos Authentication is used in Qlik Sense, a failure or error will occurArticle Number: 000039819 | Last Modified: 2019/12/05
Error: QVX_UNEXPECTED_END_OF_DATA: HTTP protocol error 401 (Unauthorized).
Currently, Kerberos Authentication is not supported with REST Connector. This is currently under investigation by R&D for future enhancement. The only workaround is not to use Kerberos Authentication.
In addition, the License and Operation Monitoring Apps will not reload anymore if using Kerberos. When trying to Reload them, the following error is observed:
Error: QVX_UNEXPECTED_END_OF_DATA: HTTP protocol error 401 (Unauthorized):
'Negotiate' authentication schema provided by the web-service is not supported or your credentials are not valid.
