Subject: Kernel 32 group limitation

Hi,

We are runing Redhat Enterprise Linux AS 2.1 ( kernel
2.4.9-e.40) on a
Dell 2650 box. There is a need in our application for
a user to belong
to more than 32 groups. Is there a way to recompile
the kernel to
support more than 32 supplementary groups ?

I'm not a subscriber of the mailing list. Please CC me
your
answers/comments posted to the list. Any help would be
greatly appreciated.

Brian Gao

New Linux 2.6 kernels support >32 groups per user. The libc also needs to be

So I guess you're out of luck with RHEL AS 2.1. I'm not sure about RHEL 3
support either..
