Using Shared Services• SDWIS Prime

– CDX for user provisioning and authentication– Role based access managed in SDWIS Prime

• CMDP – Shared CROMERR Services (SCS) for user provisioning,

authentication, and certification of submissions– Role based access is managed in SCS– Beware of tight coupling with SCS!
