Configure SAML SSO


Article summary

The SAML 2.0 (SSO) plugin allows users to log in to Totara using an account from an Identity Provider (IdP). In this instance, Totara is your Service Provider (SP).

Enable SAML SSO

You can enable the SAML authentication method by following these steps:

  1. Go to Quick-access menu > Plugins > Authentication > Manage authentication.
  2. Click the eye icon (eye_close) next to the SAML 2.0 (SSO) plugin to enable it (the eye will be open once the authentication method is enabled).

Configure an identity provider (IdP)

Once you have enabled the SAML 2.0 authentication plugin, you then need to configure an IdP, which will be available as a login option for users. In the SAML protocol, communication happens between an IdP and an SP over specific endpoints. The IdP provides the following endpoints for communication:

  • SingleSignOnService
  • SingleLogoutService

The SP provides the following endpoints for communication:

  • AssertionConsumerService
  • SingleLogoutService

To configure an IdP with Totara, you need to inform Totara of the IdP endpoints. This is done by providing Totara with the IdP's metadata (an XML file containing all of the required endpoints and a public key). You can provide the metadata by inputting a URL to fetch the metadata from or by inputting the content of the XML file directly into Totara.

Configuring an identity provider.

You also need to inform the IdP of Totara's endpoints. How this is done varies for individual IdPs. We have documented how to configure the following IdPs with Totara:

  • Okta
  • Microsoft Azure AD
  • Microsoft AD FS
For other IdPs, please refer to the identity provider's documentation on how to configure an SP.

Once both the IdP and the SP have been provided with each other's endpoints, they can communicate correctly. For a successful login request, the IdP provides a list of attributes to be used to identify the user. These attributes need to be mapped to Totara user fields to authenticate the user in your Totara instance.

Create an IdP connection

Follow these steps to create an IdP connection:

  1. Go to Quick-access menu > Plugins > Authentication > SSO SAML > Settings.
  2. Click Add Identity Provider.
  3. Give your IdP a name. This will be the name displayed to users on the login screen.
  4. Provide a link to the metadata or paste the IdP's metadata XML in the IdP metadata field.
  5. Specify a User identifier and the Totara field you want to map it to. Unique user custom fields are also available as an option.
  6. To configure the additional settings and field mappings, click Show advanced settings:
    • On the Field mappings tab, map user attributes provided by the IdP to your Totara instance user. Note that user attributes may be full URLs.
    • The Advanced settings tab contains the following options to modify Totara-specific behaviour when interacting with the IdP:
      • New users: Select how new users should be handled.
      • Existing users: Select how existing users should be handled. 
      • NameID format: Select the format you wish to use.
      • Entity ID: Override the Entity ID used in the SP Metadata.
      • Logout behaviour: Enforce logout at IdP when the user logs out of Totara.
      • Redirect after logout: Specify a redirect URL after logout.
      • Attribute Delimiter: Attribute delimiter used for IdP field mappings with multiple values.
      • Signatures: These settings are not required for secure operation, but may be useful in some cases. Select from the following options:
        • Sign metadata
        • Sign authentication requests
        • Require IdP to sign individual assertions
      • Hide on login page: If enabled the IdP will not be displayed on the login page.
      • Debug: Capture communications and the IdP for debugging purposes.
  7. Click Save.
  8. Ensure that the Status toggle is enabled to ensure the IdP will be visible on the login screen.
  9. From the Manage identity providers page, click the icon of three dots (three_dots(1)) next to the IdP and select Test to test your new IdP connection.
We have provided specific instructions for setting up SAML with Okta, Microsoft Azure AD, and Microsoft AD FS.

Migrating users to SAML 2.0 (SSO)

Users must have their authentication method set to SAML 2.0 (SSO) in order to log in via SAML. When importing users via HR import you can set the Auth option to 'ssosaml'.

Alternatively, you can set the Automatically link setting for an IdP to Existing users, and optionally check the Require email verification option. With these settings enabled, existing non-SAML users will be able to log in via SAML if they match the conditions (while still being able to use their existing login methods).

Set up SAML SSO with Okta

To set up SAML SSO with Okta, follow these steps:

  1. Sign in to Okta using your credentials.
  2. Click Admin.
  3. Go to Applications > Applications.
  4. Click Create App Integration, then select SAML 2.0.
  5. Enter a name and click Next.
  6. In Totara, go to Quick-access menu > Plugins > Authentication > SAML 2.0 (SSO) > Settings.
  7. Create an IdP.
  8. Copy the following information and enter it in Okta:
    • ACS URL -> Single sign-on URL
    • Entity ID -> Audience URI
  9. Expand the Advanced settings, then upload the certificate from Totara.
  10. Enable Single Logout.
  11. Copy the Single Logout URL from Totara to Okta.
  12. Copy the Entity ID from Totara to the SP Issuer field in Okta.
  13. Fill in the following attribute statements:
    • first_name -> user.firstName
    • last_name -> user.lastName
    • email -> user.email
  14. Click Next, select either option, then click Finish.
  15. Copy the Metadata URL from Okta, and paste it into Totara.
  16. Return to Okta, go to the Assignments tab, and select the Everyone group.
  17. In Totara, under User identifier, enter 'email' as the IdP field, and choose Email address as the Totara field.
  18. Under Field mappings, add the following mappings:
    • First name -> first_name, on every login
    • Surname -> last_name, on every login
  19. Click Save.
  20. Click the icon of three dots (three_dots(1)) and click Test to check the integration works.

Set up SAML SSO with Microsoft Azure AD
