Finally got around to install eDirectory 9.0.

I was reading through the BrainShare 2014 presentation of eDirectory
9.0, and I can't seem to find more information on some features that
were mentioned then, are they dropped or do they need to be enabled somehow?

For example there is a mention of a REST interface for eDirectory.
Better management of RFL's for improved disaster recovery? What does
that mean?

There was also mention of supporting a bunch of LDAP RFCs but I can't
see anything new in the supportedFeatures/Control/Extension in the root DSE.
