Hi Marcus

simply mistake is use of valid users on share conf. This clause block any
another users to access it and is useful for restrictive configs.
First choice to create best access system is not use valid users and write
list but create proper setup of linux passwd and groups items.
Samba automatic work with this acces rights when user is logged to share.

User on linux can own more groups needed to work.
But when you use directory ass owwner root and group Xxx when user connect
to your share have write access then new files created by it have user owner
not root and primary user group not group by updir! Then new files is not
accessible for another users of share if you not set proper create mode mask
and gruops... Samba default setup is set for user security not group.

You must understand linux file system rights for best setup samba.

If need help write bye.
