+++ This bug was initially created as a clone of Bug #251206 +++
Description of problem:
The change-password function is hard-coded to use UDP to contact a server
by default, and will only fall back TCP if the UDP server responds with a
response-too-big error, which doesn't work if the server isn't listening
for UDP clients.
Bah, tracked this with a different bug ID. Closing.
