Virtual Identity Dialogue

A Virtual Directory is a directory service (primiarly LDAP interface, though in theory other protocols like DSML or another Web Service could be used) that is unique in that it doesn't hold data in its own storage system like a traditional directory server.

Instead it aggregates, on the fly, in real-time, data from various remote services usually other LDAP or RDBMS systems but could be Web Services or other proprietary APIs as well.
