Hi Mark, We are using Netapp as a NFS server and RHEL-6 which defaults to NFSv4. NFSv4 is not using mountd protocol so "--manage-gids" would not probably work even with Linux based NFS server. That leaves us only with NFS&Kerberos - which is, as I said, pretty much no option with SGE (unfortunately as it would be the cleanest solution).

Hi Ondrej, You don't mention what OS your NFS server is, but if it's Linux there are ways to avoid the 16 group limit. I don't know if you've seen the following blog entry? http://www.xkyle.com/solving-the-nfs-16-group-limit-problem/ Best wishes, Mark ----- The information contained in this e-mail and in any attachments is confidential and is designated solely for the attention of the intended recipient(s).
