 * @file bug592.cpp  regression case for bug 592 ( "slave in "Running" state breaks authorization" ) MXS-326
 *
 * - stop all slaves: "stop slave;" directly to every node (now they are in "Running" state, not in "Russning,
 * Slave")
 * - via RWSplit "CREATE USER 'test_user'@'%' IDENTIFIED BY 'pass'"
 * - try to connect using 'test_user' (expecting success)
 * - start all slaves: "start slave;" directly to every node
 * - via RWSplit: "DROP USER 'test_user'@'%'"

 *  1. setup: Master/Slave replication
 *  2. reboot slaves
 *  3. create user usinf connection to RWSplit
 *  4. try to use this user to connect to Maxscale

 *  expected result:
 *  Authentication is ok
 *
 *  actual result:
 *  Access denied for user 'user'@'192.168.122.1' (using password: YES)

 *  In the reload users routine, if there is a master available then use that rather than the first.
