Pleiades User Directory
It would be ideal to keep all our users and groups in a central directory with one sign-on to share between Plone, Subversion, and Trac as is done by the Plone project Plone account database.
User Schema
I think the inetOrgPerson will suffice after all. See http://icon.stoa.org/trac/pleiades/browser/trunk/ldap/data.
