[mythtv-users] Switching frontends to different backends failing

[Peter Bennett]

If a backend has a pin of 0000 the frontend will connect without 
prompting for the pin.

If you have multiple backends on the network, I recommend setting a 
different PIN in each backend. This will cause the frontend to prompt 
for a PIN the first time it connects to the backend. After connecting to 
the backend the first time it stores the pin on the frontend in 
config.xml and does not prompt again for it.

This way you can make sure it is connecting to the correct backend.
