komba2 asks a lot of passwords on every full rescan of
all hosts. Once password is successfully validated
against host/share it is optionally saved for future
use. That's ok.
In case if you don't have access to a share or host
(you cannot provide valid username/password pair for
that share or host) you have the only option to cancel
attempt to browse/connect to that share/host.
The bad side is that the password will be asked on the
next network scan again. That's very inconvenient if
you do full scans frequently.
I'd like to see an option in password dialog to never
try to connect to that host/share in future (and don't
ask a password on next run :-).
I think that can be technically performed via some
reserved string value as saved password.
