Marketo cloud application

You must be signed in as a super administrator for this task.

Using Security Assertion Markup Language (SAML), your users can use their Google credentials to sign in to enterprise-cloud applications.

Set up SSO via SAML for Marketo

Here's how to set up SSO via SAML for the Marketo® application.

Step 1: Set up Marketo as a SAML 2.0 service provider (SP)
  1. From the Admin console Home page, go to Security and then Set up single sign-on (SSO).

    To see Security, you might have to click More controls at the bottom. 

  2. Click the Download button to download the Google IdP metadata and the X.509 Certificate.
  3. In a new browser tab, log into your Marketo admin account as an administrator.
  4. Navigate through Admin Integration Munchkin.
  5. Get the Munchkin Account ID. You will need it later in the following instructions.
  6. Navigate through Admin Integration Single Sign-On.
  7. Click Edit SAML Settings.
  8. Set SAML Single Sign-On to Enabled.
  9. Enter your My Domain URL i.e. https://customer.my.marketo.com in the Issuer ID field.
  10. Enter your My Domain URL i.e. https://customer.my.marketo.com in the Entity ID field.
  11. Upload your IdP Certificate.
  12. Save the settings.
  13. Edit Redirect Pages.
  14. Enter the Logout URL i.e. https://google.com.
  15. Enter the Error URL https://www.google.com/404.
  16. Save the settings and proceed to the next section to set up Google as a SAML identity provider (IdP).
Step 2: Set up Google as a SAML identity provider (IdP)
  1. In a new browser tab, sign in to your Admin console as a super administrator.
  2. Click Apps SAML apps.
  3. Click the plus (+) icon in the bottom corner.
  4. Select the Marketo item from the list. The values on the Google IDP Information page automatically populate.
  5. There are two ways to collect the service provider Setup information:

    You can copy the Entity ID and the Single Sign-On URL field values and download the X.509 Certificate, paste them into the appropriate service provider Setup fields, and then click Next
    or
    You can download the IDP metadata, upload it into the appropriate service provider Setup fields, and then  come back to the admin console and click Next.
  6. In the Basic application information window, the Application name and Description values automatically populate.
  7. Click Next.
Step 3: Enter service provider details in Google Admin console
  1. In the Service Provider Details section, enter the following URLs into the Entity IDACS URL, and Start URL fields:
            ACS URL: https://login.marketo.com/saml/assertion/munchkin-account-id
            Entity ID: http://saml.marketo.com/sp
            Start URL: <Empty>
  2. Leave Signed Response unchecked.
    When the Signed Response checkbox is unchecked, only the assertion is signed. When the Signed Response checkbox is checked, the entire response is signed.
  3. The default Name ID is the primary email. Multi-value input is not supported. 
  4.  You can change the Name ID mapping as per your requirement. Custom attributes of the user schema can also be used after creating them via Google Admin SDK APIs. The custom attributes for the user schema need to be created prior to setting up the Marketo SAML application. 
  5. Click Next.
  6. (Optional) Click Add new mapping and enter a new name for the attribute you want to map.
  7. In the drop-down list, first select the Category and then choose a User attribute to map the attribute from the Google profile.
  8. Click Finish.
Step 4: Enable the Marketo app
  1. Sign in to your Admin console.
  2. Go to Apps SAML apps.
  3. Select Marketo.
  4. At the top right of the gray box, click Edit Service Compose.

  5. To apply settings to all organizations, click On for everyone or Off for everyone, and then click Save

  6. To apply settings to individual organizational units, do the following: 

    • At the left, select the organizational unit that contains the users whose settings you want to change.
    • To change the setting, select On or Off.
    • To keep the setting the same, even if the parent setting changes, click Override.
    • If the organization's status is already Overridden, choose an option:
      Inherit—Reverts to the same setting as its parent.
      Save—Saves your new setting (even if the parent setting changes).

    Learn more about the organizational structure.

  7. Ensure that your Marketo user account email IDs match those in your Google domain.
Step 5: Verify that the SSO is working
  1. Open https://your-domain-name.my.marketo.com. You should be automatically redirected to the Google sign in page.
  2. Enter your sign in credentials.
  3. After your sign in credentials are authenticated you will be automatically redirected back to Marketo.
