Our project uses an LDAP repository for storing users. In production this will be Active Directory. For development, we seem to have a couple of options:

• Install an AD LDS instance that everyone uses
• Install an AD LDS instance on every developer machine

We're trying to keep the 'F5' experience as lightweight as possible, so installing things or relying on a central AD store aren't my favorite ideas.

There are other LDAP servers, like Open LDAP. I was hoping there might be an LDAP server that simply talks to an XML file. This would allow us to store the XML file in source control and have something that is fast and works. Our nightly builds would still use AD to pick up any differences, but the hope is since we're using LDAP it should Just Work.

Can you recommend an LDAP implementation that works well for zero-config shared-nothing development?
