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
