However, I don't quite like the way the password cache is kept up to date

What do you think?
I don't understand why this logic is preferable. Is your concern that
AH->savedPassword may contain a password even when none is needed?
The opposite, sort of. If the first connection uses a password, the
second one doesn't, and the third one does again, you need to ask for a
password again because you emptied the cache on the second attempt since
it didn't use a password. Granted, this situation is quite unlikely to
occur in practice, but I find the "correct" code *also* more readable.
To me it reads like "if the what we're caching was applied during the
connection attempt, update the cache; otherwise keep the previous value
in case it's useful in the future".
