DBIS supports maps defined in legacy RFC2307 or RFC2307bis format, as 
well as using the new format.  Migration is designed to be extremely 
easy.  In fact, it took me next to no time at all to start using 
directory entries defined in RFC2307 format from a DBIS installation, it 
really is just a matter of defining a few configuration maps that do the 
class and attribute remappings, and they are mostly standard.  See 
https://sourceforge.net/p/dbis/wiki/ConfigurationMaps-RFC2307/

DBIS is not a superset nor a child schema that inherits from RFC2307bis, 
nor is it built on top of RFC2307bis - it is a complete replacement and 
was designed as such.  RFC2307 and RFC2307bis can be completely retired 
and DBIS put in their place and there would be no omissions.  It's an 
evolution that began life by taking RFC2307bis and splitting it into 
logic units (separate internet drafts) that make for a less unwieldy 
document and make it easier for others to extend.  Then I standardised 
the client-side configuration, fixed some of the NIS incompatibilities 
that had been inherited from RFC2307, added a few much needed enterprise 
features, and that's it: a modern, modular, extensible, enterprise-ready 
RFC2307bis under another name ("2307bis" wasn't a very friendly name, 
after all, and I wasn't going to call my improvements "2307ter", but 
they could have been called that, because realistically that's what they 
are).

I don't see a reason to try to improve RFC2307bis, I think that would be 
a backwards step.  The improvements needed to RFC2307bis have already 
been made, I've done the work myself and named it "DBIS" because I 
couldn't wait for everyone else to catch-up, and I needed it last year 
:-)  I think if people started looking deeper into the DBIS internet 
drafts, making suggestions for improvement etc. we'd get to a much 
better end point than if you have people pore over RFC2307bis again.

Best regards,
Mark.
