Hello,
Thanks a lot for your answer!! 🙂 I figured it out, I hadn't activated the User Groups with the LDAP Basic (this field was not there in the 4.8.3 Version).
I can't believe I've searched for that long without noticing there was another new field to activate the User Groups in the General menu! I can now set the control access according to LDAP groups. 🙂
Many thanks! 🤘
