The Directory Guys have done a fantastic job in creating a package containing the latest and greatest OpenLDAP and associated tools for Windows. Their product is called CDS Silver and in its basic form is available free of charge to use (simple registration required). The installer optionally sets up a running slapd, a sample database and development libraries. I've tested the basic setup, and it works out of the box. The package also comes with SASL and OpenSSL so it is a fully compliant LDAP server. What is missing from the free package are a pile of OpenLDAP modules: if you want those, you have to get a subscription from Symas. Fair enough, I'd say. Thanks Guys!
