When a delete operation is replicated, and the consumer server finds that the entry to be deleted has child entries, the conflict resolution procedure creates a glue entry to avoid having orphaned entries in the directory.
In the same way, when an add operation is replicated, and the consumer server cannot find the parent entry, the conflict resolution procedure creates a glue entry representing the parent so that the new entry is not an orphan entry.
Glue entries are temporary entries that include the object classes glue and extensibleObject. Glue entries can be created in various ways:
If the conflict resolution procedure finds a deleted entry with a matching unique identifier, the glue entry is a resurrection of that entry. It also includes the glue object class and the nsds5ReplConflict attribute.
In such cases, you can either modify the glue entry to remove the glue object class and the nsds5ReplConflict attribute to keep the entry as a normal entry, or delete the glue entry and its child entries.
The server creates a minimal entry with the glue and extensibleObject object classes.
In such cases, you must either modify the entry to turn it into a meaningful entry or delete the entry and all of its child entries.
