kerberos

Hello,

I'm using Linux in a large multi-user network. Let A be some group which I'm am member of, but which is not my primary group. According to chmod(2) I should be able to chgrp a file to group A. Trying to do so succeeds on a local as well as on a NFSv3 mount, but not on a NFSv4/Kerberos mount (EPERM). Are there any special considerations regarding chgrp when using NFSv4 mounts?
