It gathers information from the domain controller and adds it to these
files.  This should include all domain users and groups.  This can be
overkill but the good thing is that if it doesn't complain in the process
or take way too long to generate, it just works.

Assign it to whatever you like.  See the '-p' flag on 'mkpasswd'.  Or just
edit the '/etc/passwd' file afterward.  Be careful not to change you user's
SID info though.

chgrp -R "Domain Users" ~

The above has not be tested.  It's meant to be an example, not a directive
of what to do literally.  See the man page for 'chgrp' for more details.
