Sun N1 Grid Engine 6.1 Installation Guide

User Names

In order for the grid engine system to verify that users submitting jobs have permission to submit them on the desired execution hosts, users' names must be identical on the submit and execution hosts involved. You might therefore have to change user names on some machines, because grid engine system users map directly to system user accounts.

Note –

User names on the master host are not relevant for permission checking. These user names do not have to match or even exist.
