Authenticating users in Liberty

The Liberty server uses a user registry to authenticate a user and retrieve information about users and groups to perform security-related operations, including authentication and authorization.

About this task

To learn about how authentication works in Liberty, see Authentication.

The authentication tasks that you can configure might vary depending on your requirements. Unless you have used the quickStartSecurity element that can configure only one user, you have to configure the user registry at the least. You do not have to configure the values for JAAS, authentication Cache and SSO tasks unless you want to change the default values. Configure TAI configuration only when you have an implementation of TAI interface to handle authentication.
