Represents the most general form of a user name. This is has the fewest constraints; other types of accounts constrain this further. User names must:
  • Be non-null
  • Be non-empty
  • Be between 1 and 255 characters
  • Must start with [a-z]
  • Uses only ASCII 0x21 through 0x7f, excluding space , : ( ) [ ] ' " | & ; A-Z \ /
  • If contains any @ symbol, must also be a valid email address. Please note that the reverse is not implied - email addresses may exist that are not valid user ids.

TODO: Should we allow Unicode here, since we now have a more restrictive User.Name for shell accounts?
