UID/GID Mapping

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

You may find this useful if:


 * You need to prevent UID and GID collisions between clients in different administrative domains
 * Two or more partner organizations would like to share data
 * You can limit access from a partner site
