Atlan currently supports some system for cross-domain identity management (SCIM) capabilities for user provisioning. However, end-to-end user lifecycle management is not supported entirely.
Atlan also supports just-in-time (JIT) user provisioning and automated assignment of user groups during first signup for several SSO providers. Once a user is deprovisioned in your SSO provider, the user will not be able to log into Atlan. Since the user profile in Atlan is not deleted automatically, you will also need to disable the user.
