All groups exist and the users are in their belonging defined group.
[homes] comment = Home Directories admin users = @admin browseable = no read only = no create mask = 0750
(Users can't write in their homes. Why?)
[pi] comment = pi Home Folder valid users = @admin write list = @admin path = /home/pi read only = no browseable = yes
(Users from admin group have no write rights. Why?)
[personal] comment = files valid users = danny path = /home/danny/personal read only = no browseable = no
(User danny has no write access.)
[downloads] comment = Download Folder valid users = @users write list = @admin path = /home/danny/downloads read only = no guest ok = no
(Admins should have write access but they haven't got it.)
Could you help me analyze the problem here?
