The enterprise-wide user identity and management systems provide user authentication information, and these kinds of integration demand the SCIM complaint rest service support in Pega. I think Pega should provide SCIM complaint rest service support in an upcoming Pega release for easy integration.
I know it is not very helpful if I don't also give a link, but if you search you can find earlier posters requesting likewise. This is supposed to be on the roadmap and your Pega rep can help to give you status.
Thank you for sharing your idea here in the Pega Collaboration Center (PCC)!
I have submitted this idea on your behalf in our internal system for feature enhancements and updated your post with the associated FDBK-ID. Please reach out to your Account Executive for more information and status updates.
