[Samba] privilages from main directory

[test test]

Hi, i have problem with inheriting permission from ovveriding directory. For
example as we can see below support is subdirectory for main but if I'd like
go to support \\IP_File_Server\main\support then i can't becouse share
support inherits main share and in fact anybody from support group can't go
into directory. Only xyz person can go to support but he could't :/. This
permission work when i go like \\IP_File_Server\support. But it's little bit
confuse becouse i have a lot of orderly subfolders in main and support
share. Is possible to resolve my problem?

 [main]
        path = /main
        writable = yes
        public = yes
        guest ok = no
        valid users = xyz

[support]
        path = /main/support
        writable = no
        create mode = 0755
        public = yes
        guest ok = no
        invalid users = xyz
        write list = @support
