http://bugs.contribs.org/show_bug.cgi?id=4590which indicates LDAP integration will not be part of sme8, so do not expect anything dramatic to happen soon with regards to the LDAP contrib or integration into sme. There were issues yet to be resolved before LDAP was ready for "prime time". It was a strong attempt to create a production ready contrib, but it is really still only in experimental stage.
Search bugzilla and the devinfo mailing list archives for more extensive info.
I'm sure I recall the "maintainers", firewall services (probably better called the lead developer for a time), calling for assistance and support for the project, in both dollars and man hours. The project was more complex than anticipated and used more manpower resources than they had available.
As far as I can tell, the project is in limbo, waiting for significant financial sponsorship and developer time.
Advertise your financial sponsorship on devinfo list and/or send an email directly to Charlie Brady and see what he says about it all.
