From Azure Active Directory via OpenID Connect to Open Liberty and Java
Long gone are the days when you had to create your own user account management, authentication, and authorization for your web delivered software. Instead, contemporary applications leverage these functions (Identity and Access Management, IAM for short) from an external provider.
