Adding a New Identity Provider Type
These instructions are for adding a new Identity Provider Type / Service (e.g. Okta, OneLogin, Azure AD, etc.). To add a new active Identity Provider, you can follow the steps in Local Setup or in our SSO Enterprise Guides on Confluence.
What Protocol will be used?
As of the writing of this documentation, there are only two protocols used for SSO (SAML and OIDC/OAuth2). We support both. Of the two, OIDC is generally easier to implement than SAML but the Identity Provider you wish to add may have a preference for one over the other. For instance, Azure AD’s workflows clearly prefer SAML.
Another thing to note about protocol choice is that OIDC is generally easier to test locally, while SAML requires testing on a publicly accessible machine like staging.
Steps for Adding the IdP Type
1. Make model changes and add migrations
You should add the new IdentityProviderType to corehq.apps.sso.models and create a migration for the sso app. Then you should add the IdentityProviderType to the appropriate protocol in IdentityProviderProtocol’s get_supported_types() method.
2. Test out the new provider type locally or on staging
It is important to consider how we will support this new Identity Provider in the long term. Once a new IdP Type is added, we will need to ensure that we can properly do regression tests during QA for any changed SSO code. In order to do this, it’s best to ensure that we are able to setup a developer/test account with the Identity Provider.
You can follow the steps in Local Setup of this section to add the new Identity Provider. The biggest challenge will likely be determining where to obtain all the requirements necessary to set up the connection in the Provider’s UI. For instance, with OIDC you need to take note of where the Issuer URL, Client ID, and Client Secret are in the UI. Some Identity Providers are more challenging to find these than others!
Pay attention to the language and field order of our forms in comparison with what a user might encounter in the Identity Provider’s UI. It might be appropriate to change the order of certain fields, sections and/or language for the Enterprise Admin SSO forms to match what the user sees in their provider’s UI.
Now you can activate the IdentityProvider. It’s easiest to use dimagi.org as the email domain to map users to, as this is a domain alias for our email accounts (e.g. emails from firstname.lastname@example.org will also go to email@example.com). Please do NOT use dimagi.com!
If you are doing tests on staging, take note you will likely have to deactivate and remove the email domain from another Identity Provider (like Azure AD or One Login) that previously used this email domain for QA. Also, if you plan to test on staging, the Dimagi SSO enterprise account mapped to the dimagi-sso-1, dimagi-sso-2, and dimagi-sso-3 domains will be ready to test this new IdP.
3. Log in as an SSO user
With the new IdentityProvider configured and active, you can now log in as an SSO user from the login screen. During this test you can identify any additional code changes that need to be made. For instance, a new OIDC IdentityProvider might not send the expected user_data through, so changes might need to be made where that data is accessed (see corehq.apps.sso.views.oidc). A new SAML provider might require changes to get_saml2_config() that are specific to its requirements (see corehq.apps.sso.configuration), but make sure that the existing IdentityProvider’s configurations remain unchanged.
4. Walk through workflows with our technical writer
Once you have verified that your changes are correctly logging in users and not throwing any errors, it’s time to proceed to setting up a meeting with a technical writer so that the setup process with the new Identity Provider can be appropriately documented on Confluence for our Enterprise partners. Another goal of this meeting should be to document any steps for the QA team to follow when setting up the Identity Provider.
5. Initiate QA
Now it’s time to initiate QA on staging for the new IdentityProviderType. In your QA request, be sure to include the new setup information as documented by our technical writer and any credentials or sign up steps for QA to obtain a developer account.
6. Determine whether a penetration test is required
If the only code changes required were language updates and adding a new IdentityProviderType this step can be skipped. However, if you needed to update something like the SAML configuration, code in the SSOBackend, or areas where authentication / user verification currently happens, then it might be a good idea to schedule a penetration test with our security firm.
7. Pilot test with the Enterprise Partner on Production
Once QA is complete and our security firm has verified that no vulnerabilities exist (if applicable), it is time to onboard our Enterprise Partner in the production environment. This will involve using the Login Enforcement option and the “SSO Test Users” feature that you will find in the Edit Identity Provider form. When Login Enforcement is set to Test, then only the SSO Test Users listed will be required to login with SSO from the homepage. This is a great way for the Enterprise partner to test their setup and processes without immediately forcing all users under their email domain to sign in with SSO.
