FreeIPA user sync to online services?

Hi all, My work is taking another look at options to enable user management with a number of third party online services. Primarily to use with AWS, Github, and Datadog. I have been looking at options such as the new AWS SSO product, OneLogin, Okta, etc Is anyone using FreeIPA with one of these types of services? Is there any safe recommended method for configuring an external facing read-only replica/user account to connect to online services? We can look at installing another on-premise app to handle the integration if required, but I am hoping we can connect FreeIPA to one of these services directly. Any help would be appreciated.
