Step 2: Configure Identity Conversion Rules

Prerequisites

An IdP entity has been created, and the login link of the IdP is accessible. (For details about how to create and verify an IdP entity, see Step 1: Create an IdP Entity.)

Procedure

If you configure identity conversion rules by clicking Create Rule, IAM converts the rule parameters to the JSON format. Alternatively, you can click Edit Rule to configure rules in JSON format. For details, see Syntax of Identity Conversion Rules.

• Creating Rules
  1. Log in to the IAM console as the administrator. In the navigation pane, choose Identity Providers.
  2. In the IdP list, click Modify in the row containing the IdP.
  3. In the Identity Conversion Rules area, click Create Rule. Then, configure the rules in the Create Rule dialog box.

     Table 1 Parameter description

     Parameter	Description	Remarks
     Username	Username of federated users in the cloud platform.	To distinguish federated users from users in the cloud platform, it is recommended that you set the username to FederationUser-IdP_XXX. IdP indicates an IdP name, for example, AD FS or Shibboleth. XXX indicates a custom name. NOTICE: The username of each federated user must be unique in the same IdP. Federated users with the same usernames in the same IdP will be mapped to the same IAM user in the cloud platform. The username can only contain letters, digits, spaces, hyphens (-), underscores (_), and periods (.). It cannot start with a digit and cannot contain the following special characters: ", \", \\, \n, \r
     User Groups	User groups which the federated users belong to in the cloud platform.	The federated users will inherit permissions from their user groups. You can select a user group that has already been created.
     Rule Conditions	Conditions that a federated user must meet to obtain permissions from the selected user groups.	Federated users who do not meet these conditions cannot access the cloud platform. You can create a maximum of 10 conditions for an identity conversion rule. NOTE: An identity conversion rule can have multiple conditions. It takes effect only if all of the conditions are met. An IdP can have multiple identity conversion rules. If a federated user does not meet any of the conditions, the user will be denied to access the cloud platform.

     For example, set an identity conversion rule for administrators in the enterprise management system.

     • Username: FederationUser-IdP_admin
     • User group: admin
     • Rule condition: _NAMEID_ (attribute), any_one_of (condition), and 000000001 (value).

       Only the user with ID 000000001 is mapped to IAM user FederationUser-IdP_admin and inherits permissions from the admin user group.

  4. In the Create Rule dialog box, click OK.
  5. On the Modify Identity Provider page, click OK.
• Editing Rules
  1. Log in to the IAM console as the administrator. In the navigation pane, choose Identity Providers.
  2. In the IdP list, click Modify in the row containing the IdP.
  3. In the Identity Conversion Rules area, click Edit Rule.
  4. Edit the identity conversion rules in JSON format. For details, see Syntax of Identity Conversion Rules.
  5. Click Validate to verify the syntax of the rules.
  6. If the rule is correct, click OK in the Edit Rule dialog box, and click OK on the Modify Identity Provider page.

     If a message indicating that the JSON file is incomplete is displayed, modify the statements or click Cancel to cancel the modifications.

Verifying Federated User Permissions

After configuring identity conversion rules, verify the permissions of federated users.

1. Log in as a federated user.

   On the Identity Providers page of the IAM console, click View in the row containing the IdP. Click to copy the login link displayed in the Basic Information area, open the link using a browser, and then enter the username and password used in the enterprise management system.

2. Check that the federated user has the permissions assigned to their user group.

   For example, configure an identity conversion rule to map federated user ID1 to the admin user group so that ID1 will have full permissions for all cloud services. On the management console, select a cloud service, and check if you can access the service.
