Nope, I meant "chown".  If the old owner of the file is defunct, the new
user might as well take ownership -- that should also allow changing
permissions.

This should happen automatically -- no need to restart things.

Did you also fix the SID?  I suggest doing a

mkpasswd -d -u YOURUSER YOURNEWDOMAIN >> /etc/passwd

and then renaming the old user in /etc/passwd to something like
"YOURUSER_old".  You can make the appropriate changes to the home
directory and login shell fields, as needed.
