How does this even work without supplying a user? I cannot get this to execute correctly on the reference node:

```
root@o9r2.dal2 17:28:20:~# mysql  -pTaaeukYLsJsJs7qpk9i4 -Nbe "show status like 'wsrep_local_state_comment'"
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
```
