Hello,I'm currently experiencing difficulties configuring SSO authentication via SAML2 between Keycloak and ProjeQtOr.Here’s what I’ve done so far:
- In ProjeQtOr, I filled in the SSO SAML2 fields under global parameters.
- In Keycloak, I created a user with the necessary information, client, and attributes (mappers).
- On my first login attempt, I changed the password, entered the email, last name, and first name, then clicked “Submit.”
However, I received the following error message:
ERROR: An exception occurred on 2025-07-08 at 17:30:01
When I check the logs, I see the following:
I'm unable to identify the root cause of the issue. Could you please help me troubleshoot this and complete the configuration?Thank you in advance for your support.Best regards,
bumet
Hi everyone, I solved the issue on my own and wanted to share the solution with you:In Keycloak > Clients > Settings, enable "Sign Assertions".
Then, in the ProjeQtOr, projeqtor/sso/projeqtor/settings.php file, set the
'wantAssertionsSigned'
value to true.
Hope this helps !Best regards,
bumet
Thanks for sharing the solution you found.
