can not authenticate on Active Directory but LdapNgPlugin works ok

I try to authenticate and authorize users against an active directory in order to create a documentation server for a small business.

just installed of FOSwiki on Ubuntu 18.04
checked that no perl dependencies are missing with this link http://serveripaddress/System/InstalledPlugins
LdapNgPlugin is working fine I find groups and users
no users have been created in foswiki

I you have any idea where to search I welcome any suggestion

I activated the logs, here's an example of failed authentication in /var/log/apache2/foswiki/error.log and I get a "dn not found"
