Just added a new concepts lesson. It clears up the single most common point of confusion for people getting into IAM. In the application world everything is an account. A user in AD, a profile in Salesforce, a service account, an API key. The moment you step into an IAM platform, all of it becomes one thing, an identity, and the identity is the source of truth the accounts hang off. One identity, many accounts, governed as one. It is in the Classroom IAM Concepts here. Drop questions in the comments.
