Automated User Provisioning: Best approach to sync Users & Security Groups?

Hi everyone,

We need to automate user creation and security group assignments in OneStream using data from an external Identity system.

I have two main questions:

1. Is it feasible to fully automate this without manual intervention?
2. What is the best way to implement it simply (avoiding heavy middleware)?

We are considering two solutions: Just-in-Time (JIT) via OIS, and SCIM. Does anyone know how we can set these up? What is the recommended "standard" approach for this?

Thanks for your help!
