Manage Access Without an Identity Domain
For a tenancy in a region not yet updated to use identity domains prior to the creation of the tenancy, users and groups are managed in Oracle Cloud Infrastructure Identity and Access Management (IAM) and Oracle Identity Cloud Service (IDCS).
Determine Whether You Use Identity Domains
If you are not sure if your tenancy uses identity domains, see Differences Between Tenancies With and Without Identity Domains.
Documentation for Identity Services
For more information about Oracle Cloud Infrastructure IAM, IDCS, and the documentation that provides the information you need, see Documentation to Use for Cloud Identity in Overview of IAM in the Oracle Cloud Infrastructure documentation.
How Roles Are Assigned in Identity Domains
Without identity domains, roles are assigned to IDCS groups, then linked to Oracle Cloud Infrastructure IAM groups using federation, as illustrated in the following diagram.
