New Revision: 21226
WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=21226
Log:
Fix bug #4377 (rename of "foo" -> "Foo" fails).
This is actually an interesting case as it exposed bad code in our DFS redirect
module (that was where the bug was introduced).
Caused by our turning on dfsroot be default.
Jeremy.
