Questions like this are pretty well addressed by the FAQ Wiki. See <http://wiki.list.org/pages/viewpage.action?pageId=4030518>, <http://wiki.list.org/pages/viewpage.action?pageId=4030582>, and <http://wiki.list.org/pages/viewpage.action?pageId=4030621>.
How far you want to go basically depends on how much work you're willing to put into the Mailman and MTA infrastructure in order to make it happen.

You'd need an LDAP member adapter -- basically, an LDAP database interface driver for Python. There was some experimental work that was done in this area for Mailman 2.1.x, but I don't think it ever got formally included in the code base. This sort of thing should be relatively easy to do with Mailman 3.x, once that ships and is stable.

There are people who are already doing this sort of thing with Mailman today, but it requires a bit of hacking on the code to put all the pieces together. We do not (yet) have an out-of-the-box solution in this space, at least not that I know of.
