Think of the Organization Unit you need to specify when installing CRM as just a container to which security can be applied. Any users you wish to add as CRM users will be added to a couple of groups that get created inside this OU. Their accounts don't
actually need to reside inside this group. Once you go through the process of adding a new user to CRM - the application will take care of adding the users to the correct groups in AD.
