newbie question: run time root and schema discovery?

[Robert Mundkowsky <rmund@pacbell.net>]

Hello,

    I read through a few LDAP rfcs and I was let wondering:

    How does a client application at run time:
        Find the root of a server?
        Find the best way to make a query (discover the indexing schema
of the server)?
        Discover all of the DNs in a server?

    Thanks,

    Robert
