Yep. Recompilation should do the trick once the kernel understands
large numbers of groups.

The only reason they use 3.0.x is they're still unable to cope
with the GPLv3 in (Open?)Solaris. Which is ironic as Oracle
Linux has been shipping GPLv3 Samba for a while. But it's a big
company, you can't expect one part to know what another part is
up to :-).
