  Choose between**None**,**SSL**, or**Transport Layer Security**. Using some form of 
  security ensures that user credentials are encrypted before being transmitted. Select 
  **SSL**to use LDAP over SSL (LDAPS) to establish secure connections using port 636 
  for negotiation and data transfer. Select**Transport Layer Security**to establish secure 
  connections using Start TLS, allowing both encrypted and decrypted connections to be 
  handled by the same port. 
  
  In this example, we choose**SSL**, as shown in Figure 4-26.
