|
|
* - 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.
