[Samba] domainuser cannot access a share

[Michael Funke]

 Hey,

I have a Windows Server 2016 as a DC and a Debian (Stretch) Server joined
the domain. I only want to use this server as a fileserver, but
domain-users cannot access the share.

Here is what I did:
smb.conf: https://paste.ubuntu.com/p/2fKDYFrZ6h/
nsswitch.conf: https://paste.ubuntu.com/p/qjKnKMtZ42/

mkdir /home/EXAMPLE/profile
chmod 1770 /home/example/profile
chgrp domänen-benutzer /home/EXAMPLE/profile
net conf addshare profile /home/EXAMPLE/profile writeable=y guest_ok=n "profile"
net conf setparm profile "profile acls" "yes"

What did I do wrong?
