Re: OpenLDAP SQL Backend

	it would be nice to have a slapd with SQL backend as a master
server for data repository. I would love to see something like that. 
So you would have a master LDAP server with possible feeds in from other
databases such as the HR database. and then replicate the data to a
frontend ldap server that uses db for fastlookups and is the actual one
clients interact with. this way data is keep current but ldap provides a
uniform interace for directory style queries.
