Integrating Auth0 with Slack
You can configure Slack to log in with Auth0. That way, users would be able to log in with any of the identity providers supported by Auth0, such as Active Directory, LDAP, Google Apps, Facebook, Google, Twitter, and so on. It will also provide Single Sign On with other clients configured.
Configuring Your Auth0 Account
Log in to the Auth0 Management Dashboard.
Select SSO Integrations.
Click the Slack box.
Set the name for your SSO Integration. Click Create.
You will be brought to the Slack Configuration Instructions page.
This page contains instructions on configuring your integration with your Slack account, which we will cover in the next section of this document.
Click on the Settings tab.
Provide the following values:
- Name: the name for your SSO integration (if you would like to change the value you provided when first setting up the integration);
- Team Name: the name of your Slack team.
- Use Auth0 instead of the IdP to do single sign on: if you would like Auth0 to handle Single Sign On instead of Slack, set the appropriate slide to green to activate this feature.
Configuring Your Slack Account
When configuring your Slack Account, please refer to the Slack Configuration Instructions page in your Auth0 Management Dashboard for the required parameters.
- Log in to the Slack Authentication Settings page as an administrator.
- Under the SAML Authentication tab, click "Configure."
- Choose Custom SAML 2.0 as the SAML Provider.
- Populate the SAML 2.0 Endpoint (HTTP) with the Auth0-provided URL. Alternatively, you can add a Connection parameter to log in with a specific identity provider. This results in Auth0 redirecting users to the specified Connection and not display the Auth0 log in widget.
- Provide the Identity Provider Issuer (optional);
- Provide the Public Certificate value.
For additional information, please consult Slack's article on enabling SAML-based single sign-on.
