I agree.

That's why these companies hire me, though.  They have *no clue* when it
comes to CIFS and they run into brick walls at full speed.

When it comes down to it, though, anyone with smarts and half a clue would
avoid SMB/CIFS if at all possible.  Most of what we do with Samba and the
CIFS client is mitigate stupidity.  :)

...and we're good at it too!
