AUTH-9222 - Unique authentication groups
Groups should be unique to ensure each user has the appropriate permissions.
How to solve
Perform a check on your group files (/etc/group and /etc/gshadow) for any double group references. Usually this indicates a typo or incorrect usage of group IDs.
Perform daily health checks of your environment, learn in-depth system hardening, and protect your systems better.Upgrade to Lynis Enterprise
