cthon failure

[Steve French]

Noticed that even with Unix Extensions on cifs mount that Samba
refuses to delete a file in this scenario (locally and presumably over
nfs it still works since it is in cthon suite).  This causes
connectathon special tests to fail

touch newfile
chmod 0000 newfile
rm newfile

(works locally but samba rejects)

Samba 4.1 rejects posix unlink (set path info) STATUS_CANNOT_DELETE
then client falls back to SMB unlink which fails.  STATUS_CANNOT_DELETE
then client falls back to a set path info of file info basic which
also fails STATUS_ACCESS_DENIED

Will do quick test with Samba master when build completes - but does
this server unlink bug look familiar (or am I missing an smb.conf that
I have forgotten about)?
