    It will help if we can put a comment here that sasl_client_init loads all the available
mechanism and factories in the sasl_lib referenced by the path

> Drill should support Kerberos based authentication from clients. This means that both
the ODBC and JDBC drivers as well as the web/REST interfaces should support inbound Kerberos.
For Web this would most likely be SPNEGO while for ODBC and JDBC this will be more generic
Kerberos.
> Since Hive and much of Hadoop supports Kerberos there is a potential for a lot of reuse
of ideas if not implementation.
> Note that this is related to but not the same as https://issues.apache.org/jira/browse/DRILL-3584
