Sorry, apparently I never received this message. It is not clear why you
conditioned it based on HAVE_GETADDRINFO; this seems to be repeated also
throughout the original code.
The patch is not fine in slapd/daemon.c (the original code seems to be broken as
well where inet_ntop(3) is already used), since peeraddr is set by inet_ntop(3)
to point to the buffer addr, and is used also when addr gets out of scope
(#ifdef HAVE_TCPD). Fixing.
