> PublickeyAuthenticator.authenticate() method is called twice, even though the first call
of this method already authenticated the user and returned true.
> This is a preformance issue, as server may need to hit database/caches to retrieve the
list of  public key(s) for the user to preform the check against.
> Or the authenticate() implementation needs to be adjusted to preform the check that the
user was alreay authenticated.
> Reproducer patch is attaced. The problem only occurs when the test is called from open
SSH client. Own SSHD's client works as expected.
> To reproduce, start the attached unit test as Java application, and issue the command:
>   ssh localhost -p 29418 -l joe
