Fixiert 500 interne Serverfehlergeräte-Manager-OSX

Für den Anfang laufe ich OS X 10.11.6 (Build 15G19009)und mein Server ist Server 5.1.5 (Build 15S7047). Ich versuche, eine Maschine über den Geräte-Manager-Bereich zu registrieren. Wenn ich auf die EnrollSchaltfläche klicke, erhalte ich einen Fehler mit dem internen 500-Server. Beim Googeln habe ich festgestellt, dass dies sehr verbreitet ist und es keine "sichere" Möglichkeit gibt, das Problem zu beheben. Beim Durchsuchen meiner Protokolldateien habe ich folgende Fehler gefunden:

Von dem, was ich zu diesem Problem gefunden habe, scheinen diese Fehler nicht zu den Lösungen zu passen. Hat jemand eine Idee, was ich hier tun kann?
