Cannot connect to Impala via ODBC

[#1]

Hi,

 does anybody know what exactly this error means?

[Cloudera][ImpalaODBC] (100) Error from the Impala Thrift API: SASL(-1): generic failure: Failed to initialize security context: No credentials are available in the security package

I have a ODBC driver 2.5.41 connecting to Impala daemon, the user has a valid ticket in the Windows machine, but the driver refuse to connect. Mechanism is Kerberos, service name, keytab .. all configured in ODBC Setup.

The impala daemon does not show any particular meaningful message in the logs about the login attempt,

Thanks
