comment Group directory challenge
The best way I can think of to acheive this is with a fuse program to perform a custom management layer. If you wanted that it would be for money not points! Alternatively you can possibly come up with a way by using pubkeys for the 'managers' to be able to login as any allowed user through the 'SSHAuthorizedKeys' command to call a special script. But that might become difficult to manage for many users and admins.

comment Group directory challenge
On a linux nfs server nfs4 acls are basically transposed onto posix acls on the local filesystem. For which the setuid bit takes precendence over the posix ACL, using ACL's looks like a non-starter.

comment Linux memory usage higher than sum of processes
This is a big guess, but you have 1124 tasks but 267 processes. It could be (probably unlikely though) that these threads (which have their own stack) take up a lots of stack space. These will not be accounted for in the count you are doing. Its unusual for this to be the case unless many threads are allocating large chunks of stack memory.

I would suggest you provide an unaltered meminfo. Also provide details of the host itself (if it is a virtual machine, etc).

comment Linux high RAM usage for unknown reason
Having read how ballooning works on vmware linux vms I think this is the cause. I am pretty unimpressed they do not offer a way from the VM side for account for the 'used' pages though.

Both outputs of /proc/meminfo you claim are for the good server? Can you provide a bad server reference too?
