# groupOfURLs

Object class for a dynamic group.

Use this object class **only for group entries**. Directory servers cache group entries based on their object class; adding this object class to non-group entries fills the group cache with spurious entries. This hurts overall group-related performance and performance for the non-group entries incorrectly identified as groups.
