Comment 7 for bug 1614010

Actually, since this report is talking about "clarifying the options", I'll mark it as Fix Released. These are the options that are currently presented:

```
ERROR This controller has already been registered on this client as "mycontroller".
To login user "bob" run 'juju login -u bob -c mycontroller'.
To update controller details and login as user "bob":
    1. run 'juju unregister mycontroller'
    2. request from your controller admin another registration string, i.e
       output from 'juju change-user-password bob --reset'
    3. re-run 'juju register' with the registration string from (2) above.
```

I will, however, create a new bug for multiple user login from one client as per comment # 6.
