6.2.2.  LOGIN Command

   Arguments:  user name
               password

   Responses:  no specific responses for this command

   Result:     OK - login completed, now in authenticated state
               NO - login failure: user name or password rejected
               BAD - command unknown or arguments invalid

      The LOGIN command identifies the client to the server and carries
      the plaintext password authenticating this user.

   Example:    C: a001 LOGIN SMITH SESAME
               S: a001 OK LOGIN completed
