Is it possible to overwrite variables defined in the configuration file /etc/cas/config/cas.properties using environment variables ?

I have a deep knowledge about LDAP. but Apereo CAS does not return attribute with tags. I think a expert guy can help me. I think he is @mmoayyed :)

Hello. I am running the CAS overlay server (5.1.9) locally for development. It is not loading my JSON services config. I'm including cas-server-support-json-service-registry as a dependency in my pom. The app is allowing logins from any HTTPS service id, instead of the app listed in my JSON file (/etc/cas/services/casSecuredApp-8900.json). Any ideas about why my config is not being used?

@cade-rea

I've been trying at this a few hours, and of course I figure it out once I post a question. I did not have cas.serviceRegistry.config.location defined correctly. Setting cas.serviceRegistry.config.location:file:/etc/cas/services fixed it.

Hello, still trying to have an ApereoCAS instance up and running :) I set up JsonServiceRegistry and RestAuthentication. my test application successfully redirect to CAS Login page, but when I enter user credentials, the CAS cannot validate the SSL peer :
cas_1 | 2020-11-27 13:47:21,351 ERROR [org.apereo.cas.authentication.PolicyBasedAuthenticationManager] - <Authentication has failed. Credentials may be incorrect or CAS cannot find authentication handler that supports [UsernamePasswordCredential(username=toto, source=null, customFields={})] of type [UsernamePasswordCredential]. Examine the configuration to ensure a method of authentication is defined and analyze CAS logs at DEBUG level to trace the authentication event.>

The fact is that I can navigate to https://users.docker:3443 from my local browser. Do you have any tip on how to make this work ?

@matrixbot

mijutu I guess you need to get java to trust the certificate of users.docker. I don't remember how to do that (I use letsencrypt), but those instructions should be easy to find. You need to add the ca cert that signed users.docker's certificate.

Hi All

I'm dealing with CAS 5.3 using LDAP as backend...

I can authenticate....

but I want to retrieve the groups the user belongs to

I know both queries and it works as expected but...

I only able to provide the last group...

I use the cas.authn.attributeRepository.ldap[0]....

I also set the cas.authn.attributeRepository.ldap[0].allowMultipleDns=true
cas.authn.attributeRepository.ldap[0].allowMultipleEntries=true

Any Idea how to set a multi value?

i query all the groups with ldap://ldap_host '(&(objectClass=posixGroup)(memberUid={user}))'

and I know some user belongs to several groups but it only reports the last one

@milu-milu

@cade-rea can you see a line like 'cas.service-registry.json.location=file:/etc/cas/services"in you cas.properties'?

Hello, I have set up CAS with WSFED and the default configuration given by the documentation (https://apereo.github.io/cas/6.2.x/configuration/Configuration-Properties.html#ws-fed-delegated-authentication) but when I head over to the log-in page it says "Authorization Denied" and i get redirected to "/cas/wsfedredirect?wsfedclientid=77f30f54-6150-46a7-a75d-7518af062c55". So... I know something is working atleast. I suspect that I need more than "org.apereo.cas:cas-server-support-wsfederation-webflow:${project.'cas.version'}" as dependency to make this work. Any guidance?

Hi i have a question about Google Authenticator is there any possibility to show again QR Code after registration ?

anosingh1

@anosingh1

Hi, I have a CAS setup for 2-factor authentication and it works fine with Chrome browser but with I.E the 2FA window doesn't show up. This appears to be the problem with URL length limit in I.E https://support.microsoft.com/en-us/help/208427/maximum-url-length-is-2-083-characters-in-internet-explorer

Any suggestions on the above query is highly appreciated

Riley W.

@rileyw

@anosingh1 Is Internet Explorer a requirement for your use case?

anosingh1

@anosingh1

@rileyw, Yes, there is an Application that is hardcoded to use I.E for authentication

Riley W.

@rileyw

What type of 2FA are you trying to rollout? Duo, Google Authenticator?

anosingh1

@anosingh1

Its a Duo

life is fantastic

Hi, i'm having trouble delegating SAML from CAS. My requested attributes are not in the SAMLRequest. Anyone had a similar issue?

P.O. TERRISSE

@PTerrisse_twitter

Hi Francisco, you have to permit attribute release, see https://apereo.github.io/cas/6.2.x/integration/Attribute-Release-Policies.html.

Francisco Castel-Branco

@Khorsan

@PTerrisse_twitter That was not the problem. pac4j (therefore, CAS) does not support Extensions for SAML AuthnRequest.

Hi All! Quick question. I'm using ClearPass in a load-balanced environment. However, when making a request to clearpass, only the tier that was originally logged in with has the password. I'm on CAS 5.1. Is there a standard solution to this?

Hi, in MFA Google Authenticator is there any possibility to check that user add TOTP QR code ? Like this is done in big applications (AZURE, GOOGLE ) ?

2/3 people just miss to scan this code and click next

lshc

@lshc666

@lgwozniak
I think this check is done by the Google Authenticator plug-in integrated by CAS. After user registration, Google Authenticator will be stored in the place you specify, such as a file in JSON format.

You can delete the QR records of these users in the records and let the users re-register

Hello. I use CAS server with SAML, and I defined the metadataLocation on the services config file. But it seems that the metadata are downloaded on the file /etc/cas/saml/metadata-backups/metadata for every services, so if I have 2 services, I can't use both

Hi, is it possible to get an authenticated principal through ldap, but the credentials are unknown in ldap?

Does anyone know how to sanitize the username? We are able to submit almost anything, but we would like to limit the allowed set of characters.
