[Twisted-Python] Passing revieved rata and erroring out bad passowrds

[Kevin Horn]

Assuming the getpass is the one the from the std lib, I don't see why you're
overriding getPassword at all.

according to the API docs, you should be able to get a custom prompt just by
adding a prompt parameter:
http://twistedmatrix.com/documents/8.1.0/api/twisted.conch.ssh.userauth.SSHUserAuthClient.html#getPassword

and you probably don't want to call succeed() on the deferred you are
returning, since that likely screws up the whole auth calback chain

if you were looking at this example:
http://www.devshed.com/c/a/Python/SSH-with-Twisted/4/
realize that it might be misleading, as the author overrides the __init__ of
his SSHUserAuthClient and passes the password in directly
(he does not prompt the user for it)

...or I could be misunderstanding the way the module works... :)

Good Luck!
