Yes those directions are still revelvant. I commented at the bottom of that post saying I was able to install ldap on x64 4.2 core. I actually tried newer packages but they require too many prereqs.

I have followed the guide on http://blogs.oregonstate.edu/sig/2013/03/28/enabling-ldap-authentication-in-zenoss-core-4-2-and-centos-6/ as well (username is uid) and it is working for me, I have used the following versions:

Products.LDAPMultiPlugins-1.14.tar.gz

Products.LDAPUserFolder-2.26.tar.gz

python-ldap-2.4.13.tar.gz

However there is a bug in Products.LDAPUserFolder-2.26.tar.gz, I have just made a bugreport here:

https://bugs.launchpad.net/ldapuserfolder/+bug/1221624

I'm not sure what exact impact the bug has, but I was noticing some WARNINGS when I restarted zenoss, and I don't like that.

Otherwise it is pretty simple, as long as you know all details of your ldap-setup :-)

If you are using ldaps (ldap over ssl) then remember that the certificate must be trusted, I had to follow this procedure: http://www.bradchen.com/blog/2012/08/openldap-tls-issue because our ldap-server has a self-signed certificate.

I'm not using groups in LDAP and my username is UID.
