41  * ldap_rename - initiate an ldap modifyDN operation. Parameters:
42  *
43  *	ld		LDAP descriptor
44  *	dn		DN of the object to modify
45  *	newrdn		RDN that will form leftmost component of entry's new name
46  *      newparent       if present, this is the Distinguished Name of the entry
47  *                      which becomes the immediate parent of the existing entry
48  *	deleteoldrdn	nonzero means to delete old rdn values from the entry
49  *                      while zero means to retain them as attributes of the entry
50  *      serverctrls     list of LDAP server controls
51  *      clientctrls     list of client controls
52  *      msgidp          this result parameter will be set to the message id of the
53  *                      request if the ldap_rename() call succeeds
54  *
55  * Example:
56  *      int rc;
57  *	rc = ldap_rename( ld, dn, newrdn, newparent, deleteoldrdn, serverctrls, clientctrls, &msgid );
