[Samba] net rpc rights grant on a standalone server

[Andrew Walker]

I have a standalone samba server. I want to configure it so that the
"admins" local unix group has the ability to view / close open files
through compmgmt.msc. I assume that what I need to do is run "net rpc
rights grant [username] SeDiskOperatorPrivilege".
Is this the correct privilege? Can these commands be run on a standalone
server? What is the proper syntax for granting this privilege to a group
rather than a user?
