Prerequisites

Access to the Keycloak UI is needed.

Procedure

1. Verify the Shasta domain is being used.

   This is indicated in the dropdown in the upper left of the UI.

2. Click on Authentication under the Configure header of the navigation area on the left side of the page.

3. Click on the Flows tab.

4. Click the dropdown button in the table header and switch to Browser.

   1. Click the Copy button in the table header.

   2. Enter RSA - Browser for the New Name type.

   3. Click the Add execution button in the table header.

   4. Switch the Provider to RSA and click Save.

   5. Update the Requirement field.

      Set the table values to the following:

      Field	Requirement
      RSA - Browser Forms	REQUIRED
      Username Password Form	REQUIRED
      RSA - Browser - Conditional OTP	CONDITIONAL
      Condition - User Configured	DISABLED
      OTP Form	DISABLED
      RSA	REQUIRED

   6. Click the Actions dropdown on the RSA line of the table, then select Config.

   7. Enter the different configuration options:

      Configuration Field	Value
      Alias	Enter the desired alias. For example, RSA could be used.
      RSA URL	The base URL of the RSA API service. For example, https://rsa.mycompany.com:5555/
      RSA Verify Endpoint	/mfa/v1_1/authn/initialize
      Keycloak Client ID	The authentication agent. For example, rsa.mycompany.com. The value is from Access > Authentication Agents > Manage Existing in the RSA Console.
      RSA Authentication Manager Client Key	The key for the RSA API.

   8. Set the Shared username if applicable.

      If the usernames are the same in Keycloak and RSA, then this can be set to ON. This means that the browser flow will not ask for the username for the RSA validation.

   9. Click Save.

5. Return to the Flows tab on the Authentication page.

6. Click the dropdown button in the table header and switch to Direct Grant.

   1. Click the Copy button in the table header.

   2. Enter RSA - CLI for the New Name type.

   3. Click the Add execution button in the table header.

   4. Switch the Provider to RSA - CLI and click Save.

   5. Update the Requirement field.

      Set the table values to the following:

      Field	Requirement
      RSA - CLI	REQUIRED
      RSA - CLI Direct Grant - Conditional OTP	DISABLED

   6. Click Save.

7. Switch to the Bindings tab in the Authentication page.

   1. Change Browser Flow to RSA - Browser.

   2. Change Direct Grant Flow to RSA - CLI.

   3. Click Save.

Verification

After this is set up, verify that it is working:

1. Point a browser at the following URL: http://auth.cmn.SYSTEM_DOMAIN_NAME/keycloak/realms/shasta/account

   The browser will be directed to the user login page. The first screen will ask for the username and password in Keycloak. After logging in this way, the next page will ask for the RSA username and token code.

2. (ncn-mw#) Get a token using the direct grant flow.

   Replace USER with a user in Keycloak, PWD_NAME with the user's password, RSA_USER with the user in RSA, and TOKEN_CODE with the token code:

   curl -i -d grant_type=password -d client_id=shasta -d username=USER \
       -d password=PWD_NAME -d rsa_username=RSA_USER -d rsa_otp=TOKEN_CODE \
       https://api-gw-service-nmn.local/keycloak/realms/shasta/protocol/openid-connect/token
