text: **4.4 Configuring user authentication**
  
  There are two methods of user authentication to control access to the GUI and to the CLI: 
  
  (cid:2)*Local authentication*is performed within the Storwize V7000 system. Local GUI 
  
  authentication is done with user name and password. Local CLI authentication is done 
  either with an SSH public key or a user name and password. 
  
  (cid:2)*Remote authentication*allows users to authenticate to the system using credentials stored 
  on an external authentication service. This feature allows you to use user credentials and 
  user groups defined on the remote service to simplify user management and access, 
  enforce password policies more efficiently, and separate user management from storage 
  management.
