My customer is seeking about smart integrations of user account registration/maintenace for both millions consumers and 100K orgnizational users.
OOTB interface is one-by-one association with roles and groups by much human efforts.
There are many ideas for that, 1st is importing popularated csv files, 2nd SOAP service interface (custom development of registration/maintence service), 3rd SAML, OpenID or some IdP Federation (if possible), 4th other custom integration with DB (like PCD), etc.
Do we have any good reference or case study within technical details?
Unfortunately, the link was not enough. The customer has more efficient "maintenance" tool already. I do ask not only for simple registration but also update the repositoy within granual orgnization schemes.
Do we have more good success story for millions user registration or POC level?
For example, LDAP listener maintence repository, or SAML one time assertion etc.
