Actually that should return the max number of groups allowed on the system.

The problem is in NFS, or to be more specifically, RPC.

Some more info on the matter:

It seems so weird that such a limitation _still_ exists.

The only solutions I thought of so far:

1. newgrp - will only work for shell-based operations
2. patch NFS - I understood that 2.4 is not to have any new feats, but why
is this not implemented in 2.6 ??
3. witch to AFS/coda - major infrastructure changes

Very surprising...and a bit disappointing...:-/
