The dn (distinguished name) of an entry is its unique identifier. A dn might be "uid=michalp,ou=Development,o=polonia-online.com". The relative dn is the base portion of this dn, namely "uid=michalp". The rest of the dn is called the parent dn, and it identifies the container in which this entry is stored. By changing the parent dn of an entry, that entry is moved to the container idendified by the parent dn. The new parent must be different from the existing one.
