The uid to SID mapping is kept in both files, so users/groups that don't
show up in the files are likely to experience permissions problems.  In
case you haven't considered these options, you can always add specific
users/groups to the files (see man pages for 'mkpasswd' and 'mkgroup') or,
if you don't mind the network access, you can keep one file on the network
for all to use, so you can update this once for everybody on some regular
basis.
