Azure AD SAML Integration

[Alexander J]

Greetings,

I was hoping someone might be able to help me identify if there is a bug with the SAML/Azure integration.

After following the guide here: 10 SAML setup with Microsoft Azure AD (zabbix.com)

I get these errors:
2023/09/19 14:35:56 [error] 668#668: *248808 FastCGI sent in stderr: "PHP message: PHP Deprecated: Parameter "/auth" is deprecated. in /usr/share/zabbix/include/classes/validators/CApiInputValidator.php on line 1475PHP message: PHP Deprecated: Parameter "/real_hosts" is deprecated. in /usr/share/zabbix/include/classes/validators/CApiInputValidator.php on line 1475" while reading response header from upstream, client: 172.16.6.151, server: zabbix.***.com, request: "POST /api_jsonrpc.php HTTP/1.0", upstream: "fastcgi://unix:/var/run/php/zabbix.sock:", host: "zabbix-cluster"

I had a similar problem recently setting up a Grafana integration, the problem there was that some API params have changed.

The thing is, this doesn't involve a third party tool and I followed the Zabbix guide for this and it seems like something is wrong.

Is anyone else using SSO with Azure AD that can confirm it's working or otherwise help me figure out why this is happening?

Thanks!

Turns out it was caused by nginx not passing all the right headers to zabbix.
