Access virtual member manager through the user registry
When configured to be used for WAS security, virtual member manager provides a built-in user registry that implements the UserRegistry Java interface provided by WAS.
If the virtual member manager is configured for multiple repositories, the combined set of users and groups in the configured repositories are available through the user registry APIs and appear to the application as a single user registry.

The WAS authentication process is based on the mechanism defined in javax.security.auth.login.LoginContext. In this authentication process, WAS provides a login module which implements the javax.security.auth.spi.LoginModule SPI interface. The login module is responsible for authenticating login principals.
