When building a client program against the libldap, it's difficult to guess the
variables $(CFLAGS) and $(LDFLAGS) according to the local system's setup.
Although dynamic linkage is ok with "-lldap" only, static linkage needs all the
dependancies.

I didn't find an autoconf test for the libldap, and it's a colossal work to
check for all the dependancies for every version and every set of options. It'd
be a lot better if OpenLDAP had a smal script "ldap-config" like many other
librairies provide. (for example gtk-config, mysql_config, sdl-config, etc.)

The following patch is a sample "ldap-config" script. I analyzed the Makefile
which builds "ldapsearch", and stole the needed variables from there.

PS: You need to regenerate configure, too.
