If local interactive users are not assigned a valid home directory, there is no place for the storage and control of files they should own.

Check

Verify all local interactive users on RHEL 8 are assigned a home directory upon creation with the following command:

$ sudo grep -i create_home /etc/login.defs

CREATE_HOME yes

If the value for "CREATE_HOME" parameter is not set to "yes", the line is missing, or the line is commented out, this is a finding.

Fix

Configure RHEL 8 to assign home directories to all new local interactive users by setting the "CREATE_HOME" parameter in "/etc/login.defs" to "yes" as follows.

CREATE_HOME yes
