Fix Recommendation

Create home directories to all local interactive users that currently do not have a home directory assigned. Use the following commands to create the user home directory assigned in "/etc/ passwd":

Note: The example will be for the user smithj, who has a home directory of "/home/smithj", a UID of "smithj", and a Group Identifier (GID) of "users assigned" in "/etc/passwd".

$ sudo mkdir /home/smithj
$ sudo chown smithj /home/smithj
$ sudo chgrp users /home/smithj
$ sudo chmod 0750 /home/smithj

Check Contents

Verify the assigned home directory of all local interactive users on RHEL 8 exists with the following command:

$ sudo ls -ld $(awk -F: '($3>=1000)&&($7 !~ /nologin/){print $6}' /etc/passwd)

drwxr-xr-x 2 smithj admin 4096 Jun 5 12:41 smithj

Note: This may miss interactive users that have been assigned a privileged User ID (UID). Evidence of interactive use may be obtained from a number of log files containing system logon information.

Check that all referenced home directories exist with the following command:

$ sudo pwck -r

user 'smithj': directory '/home/smithj' does not exist

If any home directories referenced in "/etc/passwd" are returned as not defined, this is a finding.
