[cas-user] CAS 5.2.3 IpAddress blocking& Password expiry messages & Service Maintenance notifications

[Mr Rao]

Hi,
I've been migrating from CAS 3.2.5 to CAS 5.2.3. We have below requirements 
in current code and need help on how to implement these in new version of 
CAS.

1) IP address blocking per user basis , error message should be added 
dynamically instead of using messages.properties.

2) After successful login before redirecting user to Service we want to 
display Application Maintenance notification. Info messages should be added 
dynamically instead of using messages.properties.

3)  After successful logic before redirecting user to Service we want to 
display  password expiration warning and user must be able click on change 
password to reset password. Error message should be added dynamically 
instead of using messages.properties.

I tried to modify AbstractAuthenticationAction class like below and I'm 
unable to add  my custom error message instead of using 
messages.properties.  

Whats the best practice to implement these?

Thanks
Rao


 protected Event doExecute(final RequestContext requestContext) {
        final String agent = 
WebUtils.getHttpServletRequestUserAgentFromRequestContext();
        final GeoLocationRequest geoLocation = 
WebUtils.getHttpServletRequestGeoLocationFromRequestContext();

        // TODo  -  Ip address Checking.
        Event event = iPAddressCasWebflowSupport.doExecute(requestContext);
        if (event != null) {
            return event;
        }


        if (!adaptiveAuthenticationPolicy.apply(agent, geoLocation)) {
            final String msg = "Adaptive authentication policy does not 
allow this request for " + agent + " and " + geoLocation;
            final Map<String, Class<? extends Throwable>> map = 
CollectionUtils.wrap(
                    
UnauthorizedAuthenticationException.class.getSimpleName(),
                    UnauthorizedAuthenticationException.class);
            final AuthenticationException error = new 
AuthenticationException(msg, map, new HashMap<>(0));
            return new Event(this, 
CasWebflowConstants.TRANSITION_ID_AUTHENTICATION_FAILURE,
                    new 
LocalAttributeMap(CasWebflowConstants.TRANSITION_ID_ERROR, error));
        }

        final Event serviceTicketEvent = 
this.serviceTicketRequestWebflowEventResolver.resolveSingle(requestContext);
        if (serviceTicketEvent != null) {
            fireEventHooks(serviceTicketEvent, requestContext);
            return serviceTicketEvent;
        }


        final Event finalEvent = 
this.initialAuthenticationAttemptWebflowEventResolver.resolveSingle(requestContext);

        fireEventHooks(finalEvent, requestContext);

        event = notificationsCasWebflowSupport.doExecute(requestContext, 
this);

        if (event != null) {
            fireEventHooks(event, requestContext);
            return event;
        }
