Steps to reproduce:

1. Do a regular installation of zabbix on the latest ubuntu (24.02)
2. Once finish setup login to dashboard then proceed to <zabbix_url>/api_scim.php/Users?filter=userName+eq+"Admin"

Result:

**ignore the NULL* i was (lightly) editing the scim/API.php file to figure out which of the two "This filter is not supported" was getting tripped. can tell you it doesn't change how the bug works** 
Expected:
*screenshot of it working in the docker-compose environment, also at the latest version*

 

Ive been setting up SSO/SAML with entra ID when i came across this problem, originally wasnt using the "Admin" for it as it was using the super Admin token with its Provisioning testing tool, but still was throwing up the "filter is not supported" 

i tried changing userName to displayName in conjunction to the /Groups? and that wasnt working either.
i tried comparing the contents of the /usr/share/zabbix/include/classes/scim/ to the docker environment but i couldn't find any differences 
Even install php8.3 on the azure machine to see if that would work because the docker environments have it, but that didnt change anything
