Follow these commands to change the user's uid and primary group gid.

First check the users UID and GID, as well as the GIDs name like this:
<code>
cat /etc/passwd | grep <username>
id <username>
</code>
This will give you all the output you need. Now use these commands to change the UIDs and ownership of the files:
<code>
usermod -u <NEWUID> <LOGIN>
groupmod -g <NEWGID> <GROUP>
find / -user <OLDUID> -exec chown -h <NEWUID> {} \;
find / -group <OLDGID> -exec chgrp -h <NEWGID> {} \;
</code>

> Note that on old versions you might also have to do this: {{{usermod -g <NEWGID> <LOGIN>}}}. On new versions this is not longer required.

> Note that if you have NFS shares which also holds these uid/gid you need to follow the same procedure there if you have root squash enabled. You will get permission denied messages when you run into this.
