openssh unix dev - Aug 2000 - IRIX 6.5.5m openssh-2.1.1p4 IRIX_AUDIT PROBLEM

There is an error when installing ssh as a non root user on 
SGI IRIX 6.5.5m. See the error below when negotiating connection:



---BEGIN ERROR LISTING---

The acutal error is generated from lines 89-95 of uidswap.c

---BEGIN UIDSWAP CODE---
    82  /*

    86  void
    87  permanently_set_uid(uid_t uid)
    88  {
    89  #ifdef WITH_IRIX_AUDIT
    90          if (sysconf(_SC_AUDIT)) {
    91                  debug("Setting sat id to %d", (int) uid);
    92                  if (satsetid(uid))
    93                          fatal("error setting satid: %.100s",
strerror(errno));
    94          }
    95  #endif /* WITH_IRIX_AUDIT */
    96
    97          if (setuid(uid) < 0)

Here is a context diff patch for a generated config.h file

Shouldn't there actually be a --enable --disable switch for the IRIX stuff
or a --with-root-install switch to see if you are going to install as root?
Anyway. Hope this helps out. If I get around to it, I'll fix the
configure.in
stuff myself and send in the patches.

Make this fatal a debug. In the case where ssh is running as a non-root
user, the failure doesn't matter.
