When a user changes their LDAP password, the add-on will throw an error about an invalid login. Instead of displaying an error about an invalid login, could the add-on not prompt for the user to enter in a password, then save the new password on a successful login? Most of the clients aren't fully aware of the "Accounts" option, and don't particularly read the error messages when they show up... If it just prompted them at the spot of the error to re-enter their password, I think that would provide a better interface for the end-user....
