I have a server (CentOS 5 Update 2) sharing a filesystem via nfs:

Creating a directory on the share:

# chmod 2775 /data/testdir
# chmod 2770 /data/testdir
5 is read / write for others
seems to work fine, and the directory looks fine from both server
and client. Right permissions, right ownerships, so far so good.
Except, a different user (userb) NOT in the same group can still do
whatever he/she wants in that directory, completely counter to what
unix permissions claim should be possible.
Both systems get user/group information via LDAP, so uids/gids are
consistent across machines.
This is a head-scratcher for me. WHY is a user who should have no
permissions able to create/modify/delete files in this directory?
