Problem with Zabbix and Keycloak (SSO)

[Lycos]

So, I'm the one who drew the short straw on my project and I am working on integrating Keycloak and Zabbix. I integrated it with Splunk with no problem, but Zabbix likes to be a challenge.

Here's the overall scenario. It is a straight http connection between Zabbix 6.0 and Keycloak 16.1.1. I click on the "Sign in with Single Sign-On link. It takes me to the Keycloak login page. When I authenticate with Keycloak, I get the following from Zabbix:

You are not logged in
- No permission for system access
-The parameter "username" is missing from the user attributes.

Here are the Zabbix settings:


I've searched all over the Internet and tried the options on there. I've tried changing the Username attributes to everything that is recommended.in the documentation. Still, the problem persists.

Any recommendations would be appreciated.

For some reason, it dropped my screenshot of the Zabbix configuration. So, let me manually type out what is in the SAML Settings dialog box.

Enable SAML authentication is checked.
IdP entity ID is http://172.16.22.207:8080/auth/realms/example.com
SSO service URL is http://172.16.22.207:8080/auth/reals.../protocol/saml
Username attribute is username
SP entity ID is zabbix (which matches the Keycloak Client Id)
Case-sensitive login is checked.

I was getting an error before.
