python-flask LDAP

Ich habe mal flask ldap auth mit dem Tutorial
https://code.tutsplus.com/tutorials/...dap--cms-23101
ausprobieren wollen, stosse aber auf Probleme, weil ich flask bisher nur vom hoeren her kenne, der Fachman geht in Deckung ;)
Nachdem ich die modul importe auf python3 (debian buster Pakete) umgebogen habe, stehe ich vor diesem Fehler und werde nicht schlau draus

Code:

Das ganze tritt in diesem HTML auf

Code:

---

{% extends 'base.html' %}    {% block container %}  Welcome to the Flask-LDAP Authentication Demo  {% if current_user.is_authenticated() %}    Hey {{ current_user.username }}!!    Click here to logout  {% else %}  Click here to login with LDAP  {% endif %} {% endblock %}
