Hello, I'm trying to implement the validation of user by using a rest API, everything seems to working well, and the test was working well in 6.3, but now I've upgrade the version of apereo to 6.5.4 and the authentication is't not working anymore, there is this message in the console :
2022-05-19 09:14:45,946 ERROR [org.apereo.cas.adaptors.rest.RestAuthenticationHandler] - <Could not resolve subtype of [map type; class java.util.Map, [simple type, class java.lang.String] -> [collection type; class jav a.util.List, contains [simple type, class java.lang.Object]]]: missing type id property '@class' (for POJO property 'attributes') cas-portal | at [Source: (String)"{"@class":"org.apereo.cas.authentication.principal.SimplePrincipal","id":"casuser","attributes":{}}"; line: 1, column: 98] (through reference chain: org.apereo.cas.authentication.principal.SimplePrincipal["attributes"])>
Did anybody have an idea to fix this issue ?
Thanks :)
If needed here is my simple code to test the rest authentication :
$test = '{"@class":"org.apereo.cas.authentication.principal.SimplePrincipal","id":"casuser","attributes":{}}'; return new JsonResponse($test, 200, array('Content-Type' => 'application/json'), true);

I've found the solution, I removed ","attributes":{}" from my response and It's working now.
PS: I've followed this doc https://apereo.github.io/cas/6.5.x/authentication/Rest-Authentication.html and I didn't notice that an empty attributes will make it failed ^^'
PS2: The search bar of 6.5 version is only broken for me ?

Thanks ;)

Hi, we configured some services required MFA when authenticate against these services. While this works for CAS applications, it doesn't work for SAML application. In this case MFA is not triggered when the user authenticates earlier against a non-MFA application. Even when logging in without a service/application (which does not trigger MFA at all) and then logging into a MFA application, MFA is not triggered and user is directly redirected back to the application. We're using CAS 6.3.6 - this this intended behavior?

Can you help us look at this problem? I think this is a security risk.

Łukasz

@lgwozniak

I don't have a clue ;) Is Your MFA is globally turn on ? Or only on one service ?

Hello, does anyone know what i have to do to solve this ??? i always get this page that says that The application you attempted to authenticate to is not authorized to use CAS. This usually indicates that the application is not registered with CAS, or its authorization policy defined in its registration record prevents it from leveraging CAS functionality, or it's malformed and unrecognized by CAS.

hi everyone, when using the CAS Maven overlay, CAS builds, as is well-known, a self-contained WAR archive. Is there a well-understood mechanism for using the jib Maven plugin to create a container image that runs such a WAR using its embedded servlet engine? I can easily build such an image using the spotify dockerfile plugin (actually its successor maintained by Jason Van Zyl), but I am exploring alternatives.

Hi, I'm trying to add a third party to authenticate to my CAS instance. They have only provided me with the following entries: Entity ID, IDP Initiated Assertion Consumer Service URL, SP Initiated Assertion Consumer Service URL, eLearning Assertion Consumer Service URL, Relay State for IDP Initiated
How do I register them as a service with this info? They do not provide a metadata URL

We have been using CAS for our applications' authentication with the regular "CAS Web flow".

One of our newer flows is doing a LoginWithoutTicket instead of credentials. So, in this flow

User was sent to CAS with
CAS_BASE_URL/loginWithoutTicket? _eventId=submit&username=@SSID@&password=@SSID@project@sessionToken&service=https://example.com/home
My code picks up the sessionToken and does the login work. Upon successful login it redirects the user to https://example.com/home. This flow is working.
In case the token was bad I need to redirect the url to a specific url and not show them the CAS login prompt.

Can someone please let me know if there is a way to do this? Any suggestions on how to achieve this would be much appreciated.

Hi, another problem we have with the management app 6.5.4 is, that it is still using default server cas.example.org:8443 instead of the cas.server.name provided in the management.yml file. Previous version works, but after upgrade the defaults are used. Somebody here which found this issue and knows a solution how to configure CAS authentication for management app?

Hello,

Excuse-me, I have a tiny question regarding MFA providers : why all of them have their order value defined as the rank provided in properties ? (e.g. https://github.com/apereo/cas/blob/6e29bc0001e3c304375efc5f8cbb04918d8f8691/support/cas-server-support-duo-core/src/main/java/org/apereo/cas/adaptors/duo/authn/DuoSecurityMultifactorAuthenticationProviderFactory.java#L58)

Although it looks like order and rank are two different properties : https://github.com/apereo/cas/blob/73f816c9e887cd1c51e3ae12483fac407b3465e2/api/cas-server-core-api-configuration-model/src/main/java/org/apereo/cas/configuration/model/support/mfa/BaseMultifactorAuthenticationProviderProperties.java#L28-L53

What is the way to override theme files on 6.x? When I was building our 5.3 deployment several years ago I would run it under Tomcat which extracted the war file completely and I could edit the template files in there and see the changes right away. Once I was done I would take the modified files back to the overlay directory commit changes.
I'm not sure how to access the theme files now on this new one. I'm running it as an executable war file.

Still, (in CAS 6.5.4) it seems not possible to force MFA for a SAML application when user already have a SSO session without MFA. No MFA prompt will be shown, users can access the MFA SAML application without using MFA. Really looks like a security bug to me. Opinions?

Anyone using Spring Boot with CAS and able to get Single Sign Out to work? Our CAS is version 6.5, and I'm using spring-security-cas version 5.7.2.

I've been working on a Spring Boot app that uses CAS for SSO for days now. Single sign on works great! And I have a logout button within the app that works as well. The problem I'm running in to is Single Logout (SLO) does not work. Meaning when I log out of another application, SLO works everywhere except for this app. When I log out of this app, though, I am logged out of everything else. So it seems like this app here isn't listening for when an SSO session is ended.
