OneLogin SAML SSO

Learn how to create a OneLogin SAML 2.0 application for Doppler SSO.

Requirements

  • Workplace domain verified (Settings page).
  • OneLogin Developer Account.

1. Initial Doppler SAML SSO Configuration

Go to the Doppler dashboard and from the menu click Team, then select the Settings tab from the top menu. Choose the Default Roles for users who login via SSO.

πŸ“˜

The Role controls the initial permissions a user will receive when their account is created. We recommend keeping it at Collaborator access to follow the principle of least privilege. Users with the Owner role can adjust this after the user has logged in once. If you scroll down further on the Settings page, you'll see a breakdown of what permissions each Role has.

After setting the Default Roles, we need to enable SAML SSO in Doppler to get access to the URLs needed to configure the OneLogin SAML SSO application.

Select the SSO tab from the top menu and scroll down to the SAML Single Sign-On section. Click the + button in the corner and choose a verified domain from the Domain Domain dropdown menu and then click Save.

Copy the ACS URL and Entity ID URLs to use when configuring the OneLogin SAML SSO application.

2. Create OneLogin Application

Click Applications from the top navigation menu, then click Add App.

Search for SAML Custom Connector (Advanced) then click on the selected app to begin the creation process.

Name the application Doppler and click Save.

Once the page reloads, click Configuration from the left menu and use the URLs from Step 1 above to make the the following changes:

  • Copy the Entity ID from Doppler into the Audience (EntityID) field in OneLogin.
  • Copy the ACS URL from Doppler into the Recipient field in OneLogin.
  • Copy the ACS URL from Doppler into the ACS (Consumer) URL field in OneLogin.

Once the URLs have been populated (it's ok to leave the ACS (Consumer) URL Validator field blank), click Save and you'll be returned to the Info tab of the application.

Once the page reloads, click Configuration from the left menu and download the SAML metadata by clicking More Actions, then SAML Metadata.

Open the downloaded XML file and copy its contents which you'll use in the next step.

3. Update Doppler SAML SSO Configuration

Navigate to the Doppler Team page and click on the SSO tab.

Scroll down to the SAML Single Sign-On section and paste in the XML metadata. Check the Enable field, then click the Save button.

4. OneLogin Application Logos

To set the logo for the new Doppler application in OneLogin, browse back to the Info tab of the application. Update the application logos using the images below, then click Save.

5. OneLogin Application Parameters

Now let's configure the parameters sent to Doppler during the sign-in process by clicking on Parameters, then the (+) button to add a new field.

Set the Field name to name, check Include in SAML assertion and click Save.

Select - Macro - for the Value field and enter {firstname} {lastname} as the macro value. Ensure Include in SAML assertion is still checked and click Save.

Then click Save to apply the addition of the name field.

6. Testing

As a OneLogin administrator, it's presumed you'll know how to sufficiently test a new SAML application, but here is a general guide.

πŸ“˜

Test sign-in flow using incognito window

Be sure to stay signed in to the Doppler dashboard until you've verified the SAML sign-in flow from an incognito window.

This will enable you to update or disable SAML SSO in the event of misconfiguration.

To quickly test provisioning is working, create or use a test user account, then from the Users section, manually add them to the Doppler application.

Now test the Doppler SAML sign-in flow by opening an incognito window and sign-in using the assigned user from the previous step.

Click on the Doppler application to initiate the sign-in process.

You should then be redirected to the Doppler dashboard for the assigned user.

Once you've verified the sign-in process is working correctly, you can apply your standard organization policies for user application assignment.

Troubleshooting

Here are some general troubleshooting tips:

  • Double-check that the Audience (EntityID) and Audience URI values match exactly what is displayed in the Doppler SAML section.
  • Ensure that the name parameter has been added to the Parameters section.
  • Check that the SAML metadata in Doppler is the same as provided by your application.

If you're still running into issues, the error page should present you with a requestId value that can be used by our support team for further diagnosis.

Awesome Work!

Your OneLogin SAML application is now ready to go!
