This is classic Samba.

It's been like this since as long as I can remember (well 1.9.15p8
anyway :) ).

Samba doesn't support the additional groups as defined in /etc/groups
(or your NIS (etc.) equivalent).  Only the primary group as defined in

The group id for any given share can be changed with 'force group'.
(although for various reasons I always use 'force user', not least
because then the inode cna be written allowing 'mtime' to be written)

I dunno, but I'm guessing that getting Samba to fully support
multi-groups would be a major modification.
