+# Configure Kyuubi to use JDBC Authentication
+
+Kyuubi supports authentication via JDBC query with JDBC. A query is prepared with username/password value and sent to database configured in JDBC URL. The authentication passes if result set returns at least one row.
+
+The query sql must start with `SELECT`. Placeholders are supported for sql template:
+- `${username}`
+- `${password}`
+
+For example, `SELECT 1 FROM auth_db.auth_table WHERE user=${username} AND 
+passwd=MD5(CONCAT(salt,${password}))` will be prepared as: `SELECT 1 FROM auth_db.auth_table WHERE user=? AND passwd=MD5(CONCAT(salt,?))` with value replacement of `username` and `password` in string type.
+
+## Enable JDBC Authentication 
+
+To enable the jdbc authentication method, we need to
+
+- put the JDBC driver jar package to ``$KYUUBI_HOME/jars`` directory to make it visible for
