That should have been clear from the writeup.  Just continue to use
/etc/passwd and /etc/group if you're not comfortable to change your
local SAM.  But my mail also contains examples how to change your SAM
entry from the CMD or bach command line.

Nope.  Try something time-consuming you're doing every day under
time(1), I guess.  Building some project or so.  But first get
comfortable with the new output of `id' and `ls -l' in some
environments.  I'm all for performance, but functionality first, please.
