If you are using IDCS as your only identity management system, proceed with adjusting the IDCS cloud settings and perform the user community setup. Otherwise if the user identities are managed by an existing enterprise identify management system then evaluate any Federated Single Sign On (SSO) requirements. If the federation is required for all user accounts, including the implementation team, immediately proceed with the federated SSO setup as described in Chapter 9: Using Federated Single Sign-On. Otherwise, if the federation is required for the actual production users only, it may be configured in the later stages.
