Applies to

  • ONTAP 9
  • NFS
  • AIX servers
  • Linux servers

Answer

  • ONTAP does not have a built-in mechanism to aggregate or override multiple client-side UIDs into a single UNIX user. Therefore, this requirement cannot be achieved using ONTAP-specific features alone.
  • However, NetApp ONTAP's NFS export policy includes the -anon parameter, which can be used to map access from "anonymous users" to a specified UID. 
Note:
  • The -anon parameter does not apply to "all users."
  • It is only mapped to that UID when a user is recognized as an "anonymous user" (for example, in cases such as root squash or unauthenticated access).
  • For normal user access (when a UID is explicitly sent), that UID is used as is.
