Looking back at this path a little...
Not sure if this is needed with NetBSD, but: Is the ldapsearch you use from $PATH the same as the one you compiled with -D_NETBSD_SOURCE?
Does include/portable.h define HAVE_SYS_UN_H? If not, config.log hopefully shows why.
If yes, does LOCAL_CREDS get defined when you compile daemon.c? Try e.g. cd servers/slapd rm daemon.o make daemon.o and run the resulting compilation command without '-c -o daemon.o' and see if the LOCAL_CREDS part gets #ifdeffed out.
