Yep, this is a real problem
But I think linux 2.6 hasn't this limitation anymore
(I'm not completely sure but I read something like that anywhere...)
I've tried this on SuSE9.0 with a linux 2.6 test kernel
but a user still only has 32 groups attached :-(
I'm not sure but maybe it's only glibc which is limiting this. to that the
setgroups() function only registers 32 guid to the kernel.
Volker, is this the right?
