Ensure local user Home directories exists

MoyenneNiveau 1Automatiséeaix

Description

All accounts must have a trusted started point - a HOME directory. A missing home directory on many systems places the account in a default directory. Examples include: / and /home/guest. This recommendation is specifically about locally administered accounts (in AIX terms, -R files). Audit: unlocked accounts with uid >= 200 must have an existing HOME directory.
