3. Select the Show password check box, and then write down the value that's displayed in the Password box.
4. Select Review + create.
Select Create.

Assign the Microsoft Entra test user

In this section, you'll enable B.Simon to use single sign-on by granting access to Alibaba Cloud Service (Role-based SSO).

Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
Browse to Identity > Applications > Enterprise applications > Alibaba Cloud Service (Role-based SSO).
In the app's overview page, find the Manage section and select Users and groups.
Select Add user, then select Users and groups in the Add Assignment dialog.
On the Users and groups tab, select u2 from the user list, and click Select. Then, click Assign.
View the assigned role and test Alibaba Cloud Service (Role-based SSO).

Note

After you assign the user (u2), the created role is automatically attached to the user. If you have created multiple roles, you need to attach the appropriate role to the user as needed. If you want to implement role-based SSO from Microsoft Entra ID to multiple Alibaba Cloud accounts, repeat the preceding steps.

Configure Role-Based Single Sign-On in Alibaba Cloud Service

Sign in to the Alibaba Cloud RAM console by using Account1.
In the left-side navigation pane, select SSO.
On the Role-based SSO tab, click Create IdP.
On the displayed page, enter AAD in the IdP Name field, enter a description in the Note field, click Upload to upload the federation metadata file you downloaded before, and click OK.
After the IdP is successfully created, click Create RAM Role.
In the RAM Role Name field enter AADrole, select AAD from the Select IdP drop-down list and click OK.

Note

You can grant permission to the role as needed. After creating the IdP and the corresponding role, we recommend that you save the ARNs of the IdP and the role for subsequent use. You can obtain the ARNs on the IdP information page and the role information page.
Associate the Alibaba Cloud RAM role (AADrole) with the Microsoft Entra user (u2):

To associate the RAM role with the Microsoft Entra user, you must create a role in Microsoft Entra ID by following these steps:
1. Sign in to the Microsoft Graph Explorer.
2. Click modify permissions to obtain required permissions for creating a role.
3. Select the following permissions from the list and click Modify Permissions, as shown in the following figure.
  
  Note
  
  After permissions are granted, sign in to the Graph Explorer again.
4. On the Graph Explorer page, select GET from the first drop-down list and beta from the second drop-down list. Then enter https://graph.microsoft.com/beta/servicePrincipals in the field next to the drop-down lists, and click Run Query.
  
  Note
  
  If you are using multiple directories, you can enter https://graph.microsoft.com/beta/contoso.com/servicePrincipals in the field of the query.
5. In the Response Preview section, extract the appRoles property from the 'Service Principal' for subsequent use.
  
  Note
  
  You can locate the appRoles property by entering https://graph.microsoft.com/beta/servicePrincipals/<objectID> in the field of the query. Note that the objectID is the object ID you have copied from the Microsoft Entra ID Properties page.
6. Go back to the Graph Explorer, change the method from GET to PATCH, paste the following content into the Request Body section, and click Run Query:
```
  {
    "appRoles": [
      {
        "allowedMemberTypes": [
          "User"
        ],
        "description": "msiam_access",
        "displayName": "msiam_access",
        "id": "41be2db8-48d9-4277-8e86-f6d22d35****",
        "isEnabled": true,
        "origin": "Application",
        "value": null
      },
      {
        "allowedMemberTypes": [
          "User"
        ],
        "description": "Admin,AzureADProd",
        "displayName": "Admin,AzureADProd",
        "id": "68adae10-8b6b-47e6-9142-6476078cdbce",
        "isEnabled": true,
        "origin": "ServicePrincipal",
        "value": "acs:ram::187125022722****:role/aadrole,acs:ram::187125022722****:saml-provider/AAD"
      }
    ]
  }
```
  Note
  
  The value is the ARNs of the IdP and the role you created in the RAM console. Here, you can add multiple roles as needed. Microsoft Entra ID will send the value of these roles as the claim value in SAML response. However, you can only add new roles after the msiam_access part for the patch operation. To smooth the creation process, we recommend that you use an ID generator, such as GUID Generator, to generate IDs in real time.
7. After the 'Service Principal' is patched with the required role, attach the role with the Microsoft Entra user (u2) by following the steps of Assign the Microsoft Entra test user section of the tutorial.

Configure Alibaba Cloud Service (Role-based SSO) SSO

To configure single sign-on on Alibaba Cloud Service (Role-based SSO) side, you need to send the downloaded Federation Metadata XML and appropriate copied URLs from the application configuration to Alibaba Cloud Service (Role-based SSO) support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create Alibaba Cloud Service (Role-based SSO) test user

In this section, you create a user called Britta Simon in Alibaba Cloud Service (Role-based SSO). Work with Alibaba Cloud Service (Role-based SSO) support team to add the users in the Alibaba Cloud Service (Role-based SSO) platform. Users must be created and activated before you use single sign-on.

Test SSO

After the preceding configurations are completed, test Alibaba Cloud Service (Role-based SSO) by following these steps:

Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
