-- add to the end of build.gradle

bootWar {
entryCompression = ZipEntryCompression.STORED
overlays {

Hi, We are currently using 6.3.2 version of CAS. To fix the log4j Vulnerability, we have upgraded the cas version to 6.3.7.4. After updating the version, we are facing the below issue

> Could not resolve all files for configuration ':casBootWarOverlay'.
   > Could not resolve org.apereo.cas:cas-server-webapp-tomcat:6.3.7.4.
     Required by:
         project :

        All of them match the consumer attributes:
          - Variant 'master' capability org.apereo.cas:cas-server-webapp-tomcat:6.3.7.4:
              - Unmatched attributes:
                  - Provides org.gradle.status 'release' but the consumer didn't ask for it

          - Variant 'samplessources' capability org.apereo.cas:cas-server-webapp-tomcat:6.3.7.4:

                  - Provides org.gradle.status 'release' but the consumer didn't ask for it

As per the gradle documentation, looks like there are multiple variants. Can you please help me to resolve this issue?

Hello, is there a way to disable "forgotten username" feature while leaving "reset password"? To me it seems that there is no toggle nor any easy way how to have only reset password.

hello, I am completely lost within the Apereo helpfile system. It contains so many looping links to identical pages that I have been reading the same pages for about 2,5 hours now.

There seems to be a possibility to run the war as a linux service: https://apereo.github.io/cas/6.4.x/installation/Configuring-Deployment-System-Service.html
But trying to find or build this WAR results in a bunch of files that want to create a docker machine on my virtual server and I don't want that.

Even on local we notice if no oidc config is provide it default to 8080 and not sue the tomcat port or the cas config.

whenever authentication flow fails due to invalid credentials, CAS returns HTTP status 401 with login page. Is there any way by which we can return HTTP status 200 for such cases?Because HTTP status 401 caused a monitoring alarm, I had to find a way to change it to HTTP status 200.

Hey! Nobody noticed that the last version of CAS client for Java, its build for Java 8, but have a dependency to JAXB 2.3.1 that its for Java 9 ?
Also, the READMED should clarify what version of Java it's being supported.

cas-overlay-template(6.4.4.2) is not copying resources to the final generated build with gradlew.bat build. Only customizations are packed and all other html pages are not in final build

Anyone could annotate this on the issues system that you are using ? I would liked to do this, but I don't see that I could done on GitHub repo, and I don't see a Jira o r Mantis to do it.

Hi
I am in the process of setting up two CAS servers with the same DNS rrcas.mydomain.com and the IP addresses are 10.10.10.10 and 10.10.10.11. Each CAS marks in isolation but if I activate the NGINX for both I have a ticket issue I would like to know how to configure Hazelcast (or another) to respond to the ticket issue.

if someone has already configure hazelcast or High Avalaibility CAS cluster please i need some help

Hey guys, i got a strange problem trying to activate acceptable-usage-policy with jdbc in 6.3.7.4 - After LDAP User XXX logging in, they have to accept the policy. On "ACCEPT" they'll loop on this site. Logs showing no "aupAccepted"-Attribute but attribute with value "true" is written to database - even if there is no entry for the user. When working with enabled Caching for Attribute-Repository there will be a value "1" for aupAccepted but this looks like not or wrong converted to boolean, as aup is showing "NOT ACCEPTED. Anyone else with similar issue?!

it seems not working

hey guys, does someone meet same problem?

Is anyone running into an issue where SAML services are not releasing any attributes in 6.5-SNAPSHOT? We're preparing our QA environment and noticed it pretty early in testing. CAS protocol attribute releases appear to be fine.

Could someone expand on the impact & purpose of this configuration?

For 6.4x -> 6.5-SNAPSHOT we're trying to identify the following issue:

2022-02-03 12:19:54,805 -0700 WARN [io.netty.bootstrap.Bootstrap] - <Failed to set channel option 'CONNECT_TIMEOUT_MILLIS' with value '5000' for channel '[id: 0xf39d1e89]'>

This appears to break LDAP connection for the service registry.

We've also seen a few parameters change formatting in docs, but don't necessarily error/warn in the container, so it seems confusing to debug at the moment.

Apparently 6.5 now displays all internal attributes on the login page to the user... "Principal" & "Authentication" (internal attributes here) where would one identify how to disable that?

Hello - I am new to CAS server. I am trying to integrate CAS management to CAS server but I am getting below error message.

Application Not Authorized to Use CAS
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. Contact your CAS administrator to learn how you might register and integrate your application with CAS.

I used below service configuration

{
"@class" : "org.apereo.cas.services.RegexRegisteredService",
"serviceId" : "https://localhost:8443/cas-management/",
"name" : "casManagement",
"id" : 1001,
"logoutType" : "BACK_CHANNEL",
"logoutUrl" : "https://localhost:8443/cas-management/logout"
}

solved, appending a service param can solve this.

@raymondrewalker

In CAS 6.5 when logging in (/cas/login) all internal attributes and values are showing up on the login page, even after manually disabling attribute release, by adding this:
cas.authn.authentication-attribute-release.enabled=false
Never enabled it in the past, don't use CAS for attribute release, so this is new default behavior.

We are using CAS 6.1.7 and we have set up delegated authentication with Google, Microsoft etc. Once login with Google(or with any external SSO provider like Microsoft) and then logout from the CAS, user will be logout not only from CAS but with Google account as well. Could you please someone can tell whether there a option in CAS to avoid this behavior? i.e. I want to keep Google session alive when login out from CAS. Thank you.
