Can Openldap do dynamic groups with groupofurls or not?

What does "do" mean? The original spec for dynamic groups was purely client-side, in which case any OpenLDAP server since the beginning would "do" them.

and if it can from which version did it start being able to do this. and is the schema built into openldap by default.

The dyngroup.schema file was added in September 2003. If you didn't know that, you've likely been either living under a rock for the past few years, or using a Red Hat distro...
