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.

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?!

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.

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.

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.

Hello, I found an issue with the latest release (6.5.0) when enabling cas.authn.pac4j.cas[0].auto-redirect-type=SERVER, the first login works fine, but if the application tries to login again and CAS still has the login session, the redirect to the service gets confused with the redirect to the delegated authentication and an exception is thrown, anyone else getting this issue?

Hello there,

We are trying to enable FIDO2 WebAuthN support in CAS with both Yubikeys and using the built-in browser support for FIDO2, namely for Safari on Mac OS.

While Yubikey registration and authentication works fine out of the box, when trying to register a FIDO2 device using the native Safari support for FIDO2 (without a Yubikey), we are presented with the following error on the registration step :

"java.lang.IllegalArgumentException: Failed to obtain attestation trust anchors."

Any ideas why this is happening and maybe how we can configure our own attestation trust anchors to include other sources than Yubikeys ?

Hello and I'm really glad there is a CAS chat where I can ask questions!

I was hired for my position 6 months ago at a small Community College, and the college does not have Single Sign On.

Administration purchased a product that requires SSO, and tossed it in my lap. In my investigations it turns out that SSO will cost us 50,000 (2.00 a month/user minimum) a year or more if we go with a third party.

So after much research we decided to go with CAS 6.5.x. The learning curve has been very steep as I knew nothing about SSO originally.

We decided to use GSuite as our IDP since we are using Gmail for Education as our email.

I was able to setup CAS to Delegate Authentication to Gmail and the product was set to use CAS for SSO so it worked perfectly. I'm really pleased with CAS and the documentation provided for getting this all set up.

Now for my problem :(

We have another application (Ellucian Self-Service) that students log into and we want to add SSO to this app. However, this application uses SAML2 only.

I'm having problems finding how to configure CAS to return SAML2 to this application.
I've added the

implementation "org.apereo.cas:cas-server-support-saml-sp-integrations:${project.'cas.version'}"

to build.gradle as Ellucian is one of the supported SPs. But I'm not sure what needs to be done to the registered service to get CAS to respond properly.

I would appreciate it immensely if someone can point me in the correct direction.

Hi, I was wondering if I'm miss-understanding the expected behavior of usernameAttributeProvider or if it's a bug (and if there is an alternate solution).
I have the following service:

{
  "@class": "org.apereo.cas.support.oauth.services.OAuthRegisteredService",
  ...
  "usernameAttributeProvider": {
    "@class": "org.apereo.cas.services.PrincipalAttributeRegisteredServiceUsernameProvider",
    "usernameAttribute": "uidNumber",
    "canonicalizationMode": "NONE"
  },
  ...
}

The goal is to provide to this service another identifier than the one used for other services (default identifier for other services is uid).
N.B.: both (uid and uidNumber) come from LDAP.

This works well (I can connect to the service), but I detected an unexpected behavior.
When a user connects to the above-mentioned service, in CAS logs, the WHO: is the uid for every ACTION except for SERVICE_TICKET_VALIDATED for which it is the uidNumber.
After connecting to the above-mentioned service (and only after connecting to this specific service), if the user accesses an OidcRegisteredService service, the sub in the OIDC response is the uidNumber whereas it is expecting to receive the uid (which makes it fail to authenticate the user). The OidcRegisteredService` service configuration doesn't provide any specific config for the usernameAttribute:

{
  "@class": "org.apereo.cas.services.OidcRegisteredService",
  "serviceId": "...",
  "name": "...",
  "id": ...,
  "clientId": "...",
  "clientSecret": "...",
  "bypassApprovalPrompt": true,
  "scopes": ["java.util.HashSet", ["openid", "profile", "email", "offline_access"]]
}

That means that depending on whether the user connected to the first described OAuthRegisteredService or not, he can connect to the OidcRegisteredService service or not.
Note that it doesn't affect other RegexRegisteredService services or a SamlRegisteredService that specifies its own usernameAttributeProvider

Am I missing something? Should I force the usernameAttributeProvider in the OidcRegisteredService? Why?

Hi, I'm trying to get started with CAS 6.4 (previous user of 5.3) . I have this in /etc/cas/config/cas.properties

server.port=8080
server.ssl.enabled=false
cas.server.tomcat.http.enabled=false
cas.server.tomcat.http-proxy.enabled=true
cas.server.tomcat.http-proxy.secure=true
cas.server.tomcat.http-proxy.scheme=https

Trying to run standalone executable but ultimately it crashes on this message The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.

I'm not sure where to set secretRequired=false

This will be running behind HAProxy

I had posted here but before I continue trying to confirm would like to get dev feedback. It seems that the MFA triggers, at least 'Principal Attribute Per Application' does not work when there is more than a single provider supplied. Example, [ "mfa-gauth", "mfa-webauthn"] it doesn't trigger, changing to either [ "mfa-gauth"] or [ "mfa-webauthn"] triggers.
