You're kind of on your own here. You can download and compile which ever packages work for you, the Netscape LDAP C SDK, the mozilla LDAP package from CVS, or the Open LDAP development libraries. I have attempted this with Netscape LDAP C SDK, archives of the mozilla LDAP module and the Open LDAP libraries. The only one that worked for me was pulling the mozilla LDAP module from CVS. Please check out the mozilla LDAP module page on the mozilla website and the CVS man page for instructions on how to do this. Anyone who would like to clean up this process, please let me know what you find out.
