Hi,
                                                                           
 We have quarterly vulnerability                                           
 scans on our servers and this LDAP                                        
 vulnerability always comes back up                                        
 for my Unity Voicemail Server. I                                          
 have tried unsuccessfully to address                                      
 this  issue. Is anyone aware of a                                         
 patch release for this or specific                                        
 instructions on how to address the                                        
 vulnerability?                                                            
                                                                           
 "Disable NULL BIND on your LDAP                                           
 server. In addition the LDAP bind                                         
 function in Exchange 5.5 has a                                            
 buffer overflow that allows a user                                        
 to conduct a denial of service or                                         
 execute commands in all versions

 Coupled with a NULL BIND, an                                              
 anonymous user can mount a remote

 "What lies behind us and what lies
