[CentOS] too many groups for a user?

Hi,

we're exporting a number of directories via samba shares. To manage
access for individual users, the files are put into different groups,
users who get access to the files will be put into the respective groups.

It seems there's a limited number of groups that a user can be member of
- googling around comes up with wildly different numbers from 16 up to 64k.

The limit for CentOS seems to be around 32 ... can anyone confirm?

Thanks,
