That test for you is simple: Use a plain solaris with *no* samba installed.
Create 17 (or 33 if your kernel is patched) groups. Create a user and put him
into 17 groups. Do a 'su -' to that user and see whether he can use rights from
all the groups. No samba involved. If that fails for one group, it does not
matter how we try to figure out what limit there is. There *is* a hard limit.
