Thanks for the information. I will try this out in a few days.

The reason why I choose a self-compiled installation is, that I will not 
get trouble when I run apt-get upgrade or other package installation 
tasks on the machines and get all the same versions on the machines.

Yes thanks that's true.  I did not know that the getend group command 
also list member of domain groups..

I think that's the main problem here. But I realy don't know why.

When I look up in the ADUC on my Windows Host, the user james.bond is 
member of the domain global group. And the domain global group is member 
of the domain local group, like that:

- james.bond -> Member of: sec-admin-home-fileshare-administrato

- sec-admin-home-fileshare-administrator -> Member of:

- sec-file-home-administrator  -> Assigned as ownergroup of Fileshare 

( I also put the user directly inside the sec-file-home-administrator an 
tested the szenario)

*All of them has an GID and can be find by getend, the output is:*

# getent user "DOMAIN\james.bond"


#  getent group "DOMAIN\\james.bond-group"


# getent group "DOMAIN\sec-admin-home-fileshare-administrator"


# getent group "DOMAIN\sec-admin-home-fileshare-administrator"


But the group members are not showing.. There for, the user can't setup 
the ACL permissions for the file. He is not authorized. Also the Domain 
Users group and every other group I fill with users is not showing them 
up. Even not, when added enum winbind in global section of smb.conf:

winbind enum users = yes

winbind enum groups = yes

winbind use default domain = yes

Did I miss anything or is something destroyed?

Can you give me some tips, how I can troubleshoot the issue in details.

My nsswitch.conf is:

# /etc/nsswitch.conf
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         files winbind systemd
group:          files winbind systemd
shadow:         files
gshadow:        files

hosts:          files dns winss
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis
