Specify a supplementary group profile to which the User ID is to be attached.
Enter the supplementary group by selecting the Supplementary Groups in the Definition tab and then entering the User profile of the secondary group in the Details tab. You can press the ellipsis button to obtain a list of current users to select from.
Any profile used as a group cannot have groups of its own. Similarly, any profile having a group or groups cannot be a group to another user.
