 - Modify any of the Unix-related properties. 
The GID Number is the unique identifier for a Unix group. Ideally, each Windows group is assigned a unique Group ID number. By default the Integration Pack generates a unique ID automatically. If you change the GID Number, the Integration Pack checks to ensure the specified value is unique among Unix-enabled groups.
