commit f1021e4c8d5ace6356c5b2106153288a6eb89a6b
Author: Jeremy Allison <jra at samba.org>
Date:   Mon May 19 13:11:27 2008 -0700

    Restructuring of code to fix #5460. Remove search
    by name code from conn, we were already doing the
    same check in the dfs_redirect() function, so move
    it into parse_dfs_path() instead.
    Jeremy.
