Hello,

Same problem with CAS 4.07. I followed the CAS Installation documentation  with manual installation and Docker image of knowage 7.1.7 CE Edition. Same results and same error message in knowage.log.

Some help would be really appreciated.

Hi,

Did you manage to get CAS working with Knowage ?
I face the same error 500 after successful login in CAS.
Same JWT parsing error in the log : https://pastebin.com/aGkah71c

I'm using Knowage 7.4.6

Thanks

Answer 2

Hello,

Same problem for me with Knowage 8.0.1, will this bug ever be fixed ?

If CAS integration is broken, I won't use Knowage at all.

Thanks

Dear Pierre,
We are using CAS and Knowage in some projects, so this integration is working.

Some configuration detail could be wrong, if you describe in detail the steps you did, we'll help you to configure the integration, we need to know:
- The CAS Version
- Are you using https ?
- The value of sso_class variable
- Send me the web.xml file in /webapps/knowage/WEB-INF/

Best Regards

A.

Hello,

I followed exactly the documentation here : https://knowage-suite.readthedocs.io/en/8.0/installation-guide/cas-installation.html

We use CAS version 5, https through httpd with ajp proxy, and the sso_class variable is set to value="it.eng.spagobi.services.cas.CasSsoService3NoProxy".

Here is the web.xml : https://www.knowage-suite.com/qa/?qa=blob&qa_blobid=3396213167076084829

Also the logs : https://www.knowage-suite.com/qa/?qa=blob&qa_blobid=6444188824996670921

Thank you for your help.

Hi,

Did you have the time to take a look at the files ?

I'm still unable to login with CAS, I tried with the last Knowage version 8.0.5 but nothing changed.

Thank you
