That wasn't it, I am going to attatch the current aclocal.m4. the
$ac_save__LIBS does get set prior to my adding to it. I appreciate any
help I can get. You know I also had a hard time finding any tutorials
on using the acinclude.m4 stuff using google. I could find man pages
etc. but no real in depth resources on creating custom macros, do you
know of any good books on the subject as well?

Your macro also uses $ac_save__LIBS without ever setting it.
You probably just wanted
LIBS="-lldap $LIBS"
instead.
