commit f742623b7b8a19ff3230754562deeac7657cd8cd
Author: Nadezhda Ivanova <nadezhda.ivanova at postpath.com>
Date:   Sun Mar 7 21:42:53 2010 +0200

    Added a check for permissions to modify the RDN attribute on rename.
    
    Necessary because rdn module will be moved lower than acl in the stack.
