Nach der Neuinstallation von OS X und der Migration meines Kontos über Time Machine kann ich keine SSH-Verbindung zu localhost herstellen. Es fragt mich nach einem Passwort, nimmt aber nicht das Passwort meines tatsächlichen Benutzers.
Ich habe auch versucht, einen ~/.ssh/authorized_keys-Eintrag einzurichten, aber er fordert immer noch zur Eingabe des Passworts auf. Ich habe sogar versucht, meinen SSH-Schlüssel neu zu erstellen, was nicht geholfen hat.
Hier ist meine ausführliche ssh-Ausgabe:

Irgendwelche Ideen zu dem Problem oder wie man weiter debuggen kann?
Bearbeiten: Ich habe dolan@localhost beim SSH versucht, und das gleiche Ergebnis. Außerdem sollte /etc/sshd_config seit der Neuinstallation der Standard sein. Ich habe versucht, UsePAM zu aktivieren (keine Logik, warum ich das versucht habe, außer dass es in einem Forum erwähnt wurde), und es hat nicht geholfen. Irgendwelche anderen SSH-Einstellungen, die geändert werden müssen?
Unter Systemeinstellungen -> Freigabe -> Remote-Anmeldung zeigt mein "Zugriff zulassen für" "Unbekannter Benutzer" unter "Nur für diese Benutzer". Dies liegt wahrscheinlich daran, dass sich die UID meines Benutzers nach der Neuinstallation geändert hat. Die Lösung besteht natürlich darin, sicherzustellen, dass sich mein Benutzerkonto in der Liste der zulässigen Benutzer befindet, oder für alle Benutzer zu aktivieren.
