Groups are collections of users that can be used as vehicles to grant access to user accounts belonging to themthe collections of users. If the group has any entitlements or access assigned to it, that access is given to each added account.
For example, if you have a group with a policy that specifies that members of that group have a home folder, each account added to the group will be given a home folder.
EmpowerID provides two methods for creating groups, the Create Group Simple method and the Create Group Advanced method. If minimal information is needed, use the Create Group Simple method for fewer fields and options. If you need to input more information or configure more properties for the group, use the Create Group Advanced method.
