At my company, the IT department consists of several teams like Microsoft, Network, Storage, Linux and VMware. To administer our environment we do not use our regular accounts (duh… 🙂 ), but instead use what we call admin accounts. Over the years, the security structure used to assign permissions to these admin accounts became poluted. Groups nested in groups nested in other groups, different group membership for team members, etc. As a result, we failed a security audit and I was tasked with cleaning this mess up using a role based access control (RBAC) like structure to achieve a transparent method of assigning permissions.
