commit e3ecb1828791e3e142dd84d7248c4ae70afe5e0c
Author: Jeremy Allison <jra at samba.org>
Date:   Mon May 19 13:11:41 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.

  We cope with either here.

+ the one pointed to by the connection.

  Unfortunately, due to broken clients who might set the
  SVAL(inbuf,smb_flg2) & FLAGS2_DFS_PATHNAMES bit and then
  send a local path, we have to cope with that too....
