He is actually a member of 27 groups. > Is the limit of 16 groups still current? I was under the impression that it is a limitation of 2.4 kernels.... Under 2.6 local group membership was expanded to 65536. NFS, however, is a standard separate from Linux, and it imposes a limit of 16 groups on the wire for the AUTH_UNIX credentials. If all your client systems are Linux, you can use the patch at: http://www.frankvm.com/nfs-ngroups/ as a work around. (Only the client systems need the patch.) I haven't used it myself, so best of luck.
