Security Realms

The package names of the security realm implementations have been renamed from com.iplanet.ias.security.auth.realm in Application Server 7 to com.sun.enterprise.security.auth.realm in Application Server 8.1. Custom realms written using the com.iplanet.* classes must be modified.

The com.sun.enterprise.security.AuthenticationStatus class has been removed.

The com.sun.enterprise.security.auth.login.PasswordLoginModule authenticate method implementation has changed as follows.

/**
    * Perform authentication decision.
    * <P> Note: AuthenticationStatus and AuthenticationStatusImpl
    * classes have been removed.
    * Method returns silently on success and returns a LoginException
    * on failure.
    *
    * @return void authenticate returns silently on successful authentication.
    * @throws LoginException on authentication failure.
    *
    */
abstract protected void authenticate()
    throws LoginException;
