odbc.ini

They can also be specified on the connection string.

HOST=10.92.111.122
PORT=21050
Database=default
AuthMech=2

The username and password supplied is correct. When I try using impala-shell, it works

Thanks

Also, please confirm if RImpala supports LDAP Integration. It is mentioned (and the code) caters for Kerberos, but probably does not support LDAP Integration. Please confirm?
