I am trying to connect Power BI with an Impala Instance via ODBC. Athentication method is Kerberos. I am able to connect to KDC and receive a valid tgt and a service ticket for impala. There is another Kerberos Instance my client mashine is connected to. If I trie to establish a ODBC connection from Power BI using ODBC Connector a get the following error:
```ODBC: ERROR [HY000] [Cloudera][DriverSupport] (1110) Unexpected response received from server. Please ensure the server host and port specified for the connection are correct and confirm if SSL should be enabled for the connection.````
The Driver uses the wrong `NameUserPrincipal` or rather realm in a method `TETSaslClientTransport`. The driver seems to use the wrong realm `REALM_01` instead of correct realm `REALM_02`. For both realms I have valid tickets in my MIT Kerberos. The following lines show the error from the driver log:
```TETSaslClientTransport::SaslLoggingCallback: ::LogUsername: +++++ enter +++++
TETSaslClientTransport::SaslLoggingCallback: ::LogUsername: Username returned by QueryCredentialsAttributes(SECPKG_ATTR_NAMES): user@REALM_01
TETSaslClientTransport::SaslLoggingCallback: ::LogUsername: User name returned by GetUsernameEx(NameUserPrincipal): user@REALM_01
Jan 13 15:11:31.060 DEBUG 12412 TETSaslClientTransport::SaslLoggingCallback: Failed to initialize security context: Das angegebene Ziel ist unbekannt oder nicht erreichbar.```
Any ideas how to solve this issue?
