UID/GID Mapping

Introduction
Using Nodemap, UIDs, GIDs and PROJIDs provided by remote clients can be mapped onto a local set of UIDs, GIDs and PROJIDs.

You may find this useful if:


 * You need to prevent UID, GID, and PROJID collisions between clients in different administrative domains
 * Two or more partner organizations would like to share data in the same filesystem
 * You can limit access from a partner site
 * You can limit administrator/root access to the filesystem
