Multiple FGTs to one SAML server

Hi All,

We have multiple FGTs(same customer different locations) for which we want to add the following:

https://docs.fortinet.com/document/fortigate/7.4.3/administration-guide/33053/outbound-firewall-authentication-with-microsoft-entra-id-as-a-saml-idp

All needs to go to a same SAML server. 

Does this mean we need to configure a separate APP on Azure for each FGT. 

Or there is another way to do this. 

Thanks

G
