Examples of org.acegisecurity.AuthenticationManager.authenticate()

org.acegisecurity.AuthenticationManager.authenticate()

Attempts to authenticate the passed {@link Authentication} object, returning a fully populatedAuthentication object (including granted authorities) if successful.

An AuthenticationManager must honour the following contract concerning exceptions:

A {@link DisabledException} must be thrown if an account is disabled and theAuthenticationManager can test for this state.

A {@link LockedException} must be thrown if an account is locked and theAuthenticationManager can test for account locking.

A {@link BadCredentialsException} must be thrown if incorrect credentials are presented. Whilst theabove exceptions are optional, an AuthenticationManager must always test credentials.

Exceptions should be tested for and if applicable thrown in the order expressed above (ie if an account is disabled or locked, the authentication request is immediately rejected and the credentials testing process is not performed). This prevents credentials being tested against disabled or locked accounts.

@param authentication the authentication request object @return a fully authenticated object including credentials @throws AuthenticationException if authentication fails

        AuthenticationManager m = delegate; // fix the reference we are working with


        if(m ==null)
            throw new DisabledException("Authentication service is still not ready yet");
        else
            return m.authenticate(authentication);
    }


    public void setDelegate(AuthenticationManager manager) {
        this.delegate = manager;
    }

    public User authenticate(String loginName, String password) {
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(
                loginName, password);
        AuthenticationManager am = (AuthenticationManager) applicationContext.getBean("authenticationManager");
        try {
            Authentication authentication = am.authenticate(token);
            return (User) authentication.getPrincipal();
        } catch (AuthenticationException ae) {
            logger.debug("acegi authentication failed: " + ae);
            return null;
        }
