Set up Workforce Identity Federation with OIDC

Register a new application for Ops Manager.

Select public client/native application as the client type.

Set the Redirect URL value to http://localhost:27097/redirect.

(Conditional) Add or enable a groups claim if you authenticate with groups.

For groups, this step ensures that your access tokens contain the group membership information of the user authenticating. MongoDB uses the values sent in a groups claim for authorization.

(Optional) Allow refresh tokens if you want MongoDB clients to refresh the tokens for a better user experience.

(Optional) Configure the access token lifetime (exp claim) to align with your database connection session time.

Register an application.

1. Navigate to App registrations.

   1. In your Azure portal account, search and click Microsoft Entra ID.

   2. In the Manage section of the left navigation, click App registrations.

2. Click New registration.

3. Apply the following values.

   Field	Value
   Name	Ops Manager Database - Workforce
   Supported Account Types	Accounts in this organizational directory only (single tenant)
   Redirect URI	- Public client/native (mobile & desktop) - http://localhost:27097/redirect

4. Click Register.

To learn more about registering an application, see Azure Documentation.

Add a group claim.

1. Navigate to Token Configuration.

   In the Manage section of the left navigation, click Token Configuration.

2. Click Add groups claim.

3. In the Edit groups claim modal, select Security.

   What groups you select depend on the type of groups you configured in your Azure environment. You may need to select a different type of group to send the appropriate group information.

4. In the Customize token properties by type section, only select Group ID.

5. Click Add.

To learn more about adding a group claim, see Azure Documentation.

Add a user identifier claim to the access token.

1. Click Add optional claim.

2. In the Add optional claim modal, select Access.

3. Select a claim that carries a user identifier that you can refer to in MongoDB access logs such as an email.

   You can use the UPN claim to identify users with their email address.

4. Click Add.

5. In the Microsoft Graph Permissions note, check the box, and click Add.

To learn more, see Azure Documentation.

Update the manifest.

1. In the Manage section of the left navigation, click Manifest.

2. Update the accessTokenAcceptedVersion from null to 2.

   The number 2 represents Version 2 of Microsoft's access tokens. Other applications can use this as a signed attestation of the Active Directory-managed user's identity. Version 2 ensures that the token is a JSON Web Token that MongoDB understands.

3. Click Save.

To learn more about adding an optional claim, see Azure Documentation.

Remember metadata.

1. In the left navigation, click Overview.

   Copy the Application (client) ID value.

2. In the top navigation, click Endpoints.
