ok, this type of wrapper is what I originally thought was meant (but I
missed detail of the expected subclass of bytes)
On reading the responses I got even more confused and figured what I
just proposed was what was being suggested :-)

Unfortunately this doesn't help with the instance where just plain
res[0]["samAccountName"][0] is being passed around (which seem to be the
ones that I have had to change lots of). Perhaps 
str(res[0]["samAccountName"][0]) is used more than I realise but I just
haven't experienced that yet (at least in terms of root causes of
runtime errors when porting tests)
I'll look into the c - code modification to provide the stringification
functionality

Thanks for the hints
