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.

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

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