text: Passwords for local users can be up to 64 printable ASCII characters. There are no forbidden 
  characters. However, passwords cannot begin or end with blanks. 
  
  When connecting to the CLI, encryption key authentication is attempted first with the user 
  name and password combination available as a fallback. The SSH key authentication method 
  is available for CLI and file transfer access only. For GUI access, only the password is used. 
  
  **Note:**If local authentication is used, user accounts must be created for each Storwize 
  V7000 system. If you want to allow access for a user on multiple systems, you must define 
  the user in each system.
