NFSv3: try get_root user-supplied security_flavor
Thanks to Ed Keizer for bug and root cause. He says: "... we could only mount
the top-level Solaris share. We could not mount deeper into the tree.
Investigation showed that Solaris allows UNIX authenticated FSINFO only on the
top level of the share. This is a problem because we share/export our home
directories one level higher than we mount them. I.e. we share the partition
and not the individual home directories. This prevented access to home
directories."
We still may need to try auth_sys for the case where the client doesn't have
appropriate credentials.
