Authentication against Ldap

The installation of TLJH comes with ldap3 version 2.8.1
With this version it is not possible to authenticate against an Ldap server (Samba).
To get this done one habe to downgrade the ldap3 version to 2.7

I cant explain why its not possible even though there is a discussion about this problem/bug…

Is the TLJH maintainers aware of this problem?
