In this document, we'll show you how to use Slack as an Identity provider for Paralus. This will allow your users to login via Slack and access Paralus. Below is the list of items that we will cover in this document:

Creating a Slack SSO Application

Login to your Slack account and Create a new Slack App. Choose a workspace that will be associated with your app.

Creating New Slack App

Leave the Application Redirect URL empty for now and create the application.

Note down the client-id and client-secret as those will be required to configure identity provider for Paralus.

You also need to configure the scopes for your Slack application. Navigate to Features -> OAuth & Permissions and add identity.basic, as scopes.

Note: Ensure that you add scopes for User Token Scopes & not Bot Token Scopes.

Adding an Identity Provider to Paralus

Login to your Paralus dashboard and navigate to System -> Identity Providers and click on New Identity Provider

Provide the name of the identity provider and choose IdP type as Slack from the drop down.

For client identifier & secret, provide the client-id & client-secret of the Slack app created earlier.

Under Scopes provide identity.basic, as scopes

For Issuer URL, provide this url:

Adding new identity provider in Paralus

Click Save & Continue.

From the next screen copy the Callback URL and paste it in the redirect URL for the Slack OAuth app created in the earlier step.

On the Mapper Configuration screen, provide as the mapper url. Click Save & Exit.

At this point, you have successfully added Slack as an identity provider for Paralus.

Verify Login with Slack

To confirm if the setup was correct, logout from Paralus.

On the login screen, you should now see a Sign In With Slack button. Click on it to begin the login process using Slack.

Login using Slack

Enter your Slack credentials and login to Slack. Allow the application to access the respective permissions/scopes and sign in.

Authenticate on Slack

Once authenticated, you'll be redirected to Paralus dashboard.

Congratulations! You've successfully configured Slack as an identity provider for Paralus.

Note: Depending on the permission, the user that logs in using Slack might not see any projects on the dashboard. As an admin, you'll have to configure their group and assign them a project.
