Check Text ( C-4595r744103_chk )
Verify all files and directories in a local interactive user's home directory have a valid owner.

Check the owner of all files and directories in a local interactive user's home directory with the following command:

Note: The example will be for the user "smithj", who has a home directory of "/home/smithj".

$ sudo ls -lLR /home/smithj
-rw-r--r-- 1 smithj smithj 18 Mar 5 17:06 file1
-rw-r--r-- 1 smithj smithj 193 Mar 5 17:06 file2
-rw-r--r-- 1 smithj smithj 231 Mar 5 17:06 file3

If any files or directories are found without an owner, this is a finding.
Fix Text (F-4595r744104_fix)
Either remove all files and directories from the system that do not have a valid user, or assign a valid user to all unowned files and directories on RHEL 7 with the "chown" command:

Note: The example will be for the user smithj, who has a home directory of "/home/smithj".

$ sudo chown smithj /home/smithj/
