> Key: DRILL-5968
> URL: https://issues.apache.org/jira/browse/DRILL-5968
> Project: Apache Drill
> Issue Type: Bug
> Reporter: Parth Chandra
> Priority: Major
>
> In the ODBC driver -
> The krbSpnConfigurationsRequired parameter in odbc.ini is not working as expected. If I set the following:
> AuthenticationType=Kerberos
> UID=
> PWD=
> DelegationUID=
> KrbServiceName=
> KrbServiceHost=maprsasl
> krbSpnConfigurationsRequired=1
> I could connect successfully. I was expecting to get an error message. If only either KrbServiceHost is missing or both KrbServiceHost and KrbServiceName are missing then I get the expected error message.
> Turning off the parameter, I was able to connect using the following setting:
> AuthenticationType=Kerberos
> UID=
> PWD=
> DelegationUID=
> KrbServiceName=
> KrbServiceHost=maprsasl
> krbSpnConfigurationsRequired=0
> However, if either KrbServiceHost or both KrbServiceHost and KrbServiceName are missing, I would get the following error message:
> 1: SQLDriverConnect = [MapR][Drill] (30) User authentication failed. Server message: DrillClientImpl::handleAuthentication: Authentication failed. [Details: Encryption: enabled ,MaxWrappedSize: 32768 ,WrapSizeLimit: 0, Error: -1]. Check connection parameters? (30) SQLSTATE=28000
> 1: ODBC_Connect = [MapR][Drill] (30) User authentication failed. Server message: DrillClientImpl::handleAuthentication: Authentication failed. [Details: Encryption: enabled ,MaxWrappedSize: 32768 ,WrapSizeLimit: 0, Error: -1]. Check connection parameters? (30) SQLSTATE=28000
> The Drill C++ Client should set service_host to the connected host (if direct) if service_host is empty (similar logic for zookeeper connection). Going through the source code, looks like this logic was removed by this commit: https://github.com/apache/drill/commit/f246c3cad7f44baeb8153913052ebc963c62276a#diff-8e6df071d8ca863fcfa578892944c1dcL123
