The ypcat program is just a thin wrapper around glibc routines.  It uses
yp_all to ask glibc to iterate over all the keys in the map doing this:

static int
print_data (int status, char *inkey, int inkeylen, char *inval,
            int invallen, char *indata __attribute__ ((unused)))
{
  if (status != YP_TRUE)
    return status;

  if (kflag  && (inkeylen > 0))
    {
      if (inkey[inkeylen - 1] == '\0')
        --inkeylen;
      fprintf (stdout, "%*.*s ", inkeylen, inkeylen, inkey);
    }
  if (invallen > 0)
    {
      if (inval[invallen -1] == '\0')
        --invallen;
      fprintf (stdout, "%*.*s\n", invallen, invallen, inval);
    }
  else
    fputs ("\n", stdout);

  return 0;
}

In any case, the major issue reported was with login and account lookups
which are handled by the NSS module provided by glibc, the RCness being
due to the inability to log in.
