VNC-Server lehnt Nicht-Root-Anmeldungen ab

Mit einem Centos 7 VM. Ich habe "xrdp" "tigervnc-server" für die Remote-Anmeldung verwendet. Ich kann das Remote-Login sehen und den Benutzernamen eingeben, aber nur das Root-Passwort funktioniert.

Hier ist xrdp.log xrdp-sesman.log für Benutzer, die nicht als Root angemeldet sind.
