Deployment of multiple Camunda instances

Good day,

I am new to camunda and am working on a project utilising it.
I am currently working on 2 separate services that each deploy their own camunda application.
They are both using the same database schemas and both use the same ldap authentication server.

My question is, what is the best way of connecting these 2 separate instances such that users of both services may seamlessly transfer between the camunda instances without the need of multiple log-ins.

Thanks

You can check it out Keycloak Identity Provider Plugin and configure your LDAP in your KeyCloak.
