As I discussed with Bruce in person, this is because the original
krb_rd_req() will fail with RD_AP_BADD, but the dialup hack will cause
the error code to become RD_AP_UNDEC. The fix is to check for (r ==
RD_AP_UNDEC) instead of just "if (r)".
It is not clear to me that using a library global variable is
preferrable to calling getpeername() on file descriptor 0 in
kerberos4_is(), but I will leave that up to Bruce.
