  Log:
  Don't use `memset' to initialize a struct passwd.  A module
  may not fill in all fields, and in the case of string fields, this could
  cause trouble for applications.  (The only likely example is `pw_class',
  because this field is not used by all modules in all cases.)
  
  Move initialization of struct passwd from module-specific code to the
  dispatch code.
  
  The problem of a NULL pw_class was
  Noticed by:     Philip Paeps <philip at paeps.cx>
                      and the c^Htrusty ssh(1) command.
