samba - Jul 2019 - Azure AD Connect - Error reference-value-not-ldap-conformant

Hello everybody,

I have a Samba4 ad (running on an Ubuntu 18.04, Samba 4.7.6)

?
This AD is used by several associations to manage users in different
applications. Now, an association was made possible via Microsoft nonprofit
Office365 access and it should be the mailboxes in Office365 hosted. For this I
have installed a Windows Server 2019 on which I installed the Azure AD Connect.

Unfortunately, syncronization does not work. Error message:

Error: reference-value-not-ldap-conformant

Attrebut: member

?
In the samba list I found the following articles:

?
I wanted to ask if there is something new in the meantime, or if someone can
help?

?
Many Thanks.


Ren?
