If you are using plain authentication and not something like LDAP you
can use usermod and edit groups with groupmod. You can manually edit
/etc/passwd or /etc/group, but you will have to manually run "chown"
across all files with the old UID/GID to update them to the new UID/GID.

After you make the GID change you will have to change the ownership of
your home to match the new GID:

# chgrp -R group /home/user

(per the groupmod[1] man page)

Also, delete any /tmp files with your old UID and chown files outside of
/home. (per the usermod[2] man page)

# chown -R user:group /opt/foo/dir

[1] Any files that have the old group ID and must continue to belong to
     GROUP, must have their group ID changed manually.
[2] The ownership of files outside of the user´s home directory must be
     fixed manually.
