In my previous post I described how to get a buildout part to get PloneLDAP with an up-to-date LDAPUserFolder. Things are even simpler now since all involved products have been released as eggs. So just list theses in your buildout along with other eggs:

eggs =
...
Products.LDAPUserFolder
Products.LDAPMultiPlugins
Products.PloneLDAP

Second important thing: LDAPUserFolder 2.9 has been released. If you used 2.9-beta you must upgrade, since an important bug related to the negative cache has been fixed. PloneLDAP documents usage with LDAPUserFolder 2.8, but 2.9 is definitely worth it: The negative cache feature avoids doing too many ldap request, especially useless/unsuccessful ones! Many thanks to Jens Vagelpohl (http://www.dataflake.org/software/ldapuserfolder).

UPDATE: all products are available as eggs. See this post.

PloneLDAP is a great product, but its bundle ships a not so recent version of LDAPUserFolder. LDAPUserFolder and LDAPMultiPlugins download urls are both ending with "/download". That seems to confuse plone.recipe.distros, because it installs just one of them. Furthermore, at plone.org PloneLDAP single product (as opposed to PloneLDAP bundle) download url ends with... a space! (%20).
So we have uploaded theses tarballs on release.ingeniweb.com. Here is a working part for buildout:

[ldap_products]
recipe = plone.recipe.distros
urls =
http://release.ingeniweb.com/third-party-dist/LDAPUserFolder-2.9-beta.tgz
http://release.ingeniweb.com/third-party-dist/LDAPMultiPlugins-1.5.tgz
