NFS Anonymous UID/GID of -1 Passes DoD STIG Guidance in SCAP-Security-Guid But is an Invalid Option

Solution Unverified - Updated -

Issue

  • The use of -1 as an anonymous UID/GID is no longer allowed in NFS due to compliance issues with kernel namespaces. The current scap-security-guide checks still recognize -1 as a valid UID/GID in the setup of an NFS export.

Environment

  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux 6
  • DoD STIG Guidelines Applied
