Where you are running MF Directory Server with 
                     			 Restrict administration access set, and you make a change to the security manager list that it uses, you are challenged to supply: 
                     			 
                      
                        				
                        - a set of credentials that are valid with the configuration prior to the changes being applied 
                           				  
                           and 
                              				  
                            
- a set of credentials that will be valid with the configuration after the changes are applied. This is to ensure that you can
                           still access the MF Directory Server screens. 
                           				
                        
If appropriate credentials are not supplied or are not valid, the changes will not be applied.
