ReadyNAS OS 6.8 allows configuring NFS User ID mapping per NFS share. This functionality ensures NFS connections use a predefined UID/GID when necessary, which prevents permission based issues on certain applications. 

Configuring User ID Mapping

  1. From the Admin Page, click Shares > Shares. 
  2. Click the share you would like to edit, then click Settings.
  3. Click Network Access > NFS > Advanced.

There are three UID/GID squashing settings:

  • No Root Squash: Allows NFS connection using root access to connect as root. (Anonymous UID/GID text boxes are disabled)
  • Root Squashing: Forces all NFS root users to use UID/GID configured in the Anonymous UID/GID text boxes.
  • All Squash: Forces all NFS users to use UID/GID configured in the Anonymous UID/GID text boxes.
