[Samba] permission bits clobbered

Of course '>' is very different of '>>'. '>' creates a new file so THE 
NEW secretfile is created with the 644 mask.
'>>' appends in the file. If you do this twice w/ '>>' you will see 
this:
foobar
foobar
But if you do the same twice but with '>':
foobar
Only once 'cause the file is created twice.
Cheers
