Updating an OAuth Setting

Configure the default token issuance policy in an identity domain in IAM.

  1. Open the navigation menu  and select Identity & Security. Under Identity, select Domains.
  2. Select the name of the identity domain that you want to work in. You might need to change the compartment to find the domain that you want.
  3. On the domain details page, select Security.
  4. On the Security page, select OAuth.
  5. Click the name of the identity domain that you want to work in. You might need to change the compartment to find the domain that you want. Then, click Security and then OAuth.
  6. Under Default token issuance policy, select Allow all resources.
    This setting allows the client to access any resource within the tenant regardless of the trust scope settings at the application level.
  7. (Optional) In the Issuer field, enter a custom issuer value. This issuer value is used in the newly issued tokens.
    If you don't specify a custom issuer, the default IDCS issuer is used:
    https://identity.oraclecloud.com/
    Caution

    Only one previous issuer value is stored. If you make frequent changes in the issuer value, the old token validation might fail.

    After changing the issuer value at the domain level, the issuer might be different on the client side based on the tenancy configuration. Validate the issuer value logic on the client side to use the new issuer value.

  8. Select Save changes.
