+
+## authentik configuration
+
+### Step 1. Create custom property mappings

+
+1. Log in as admin to your authentik instance and then click **Admin interface**.
+2. Navigate to **Customization -> Property Mappings**.
+3. Create the property mapping for `User.Email`.
+    1. On the **Property Mappings** page, click **Create**.
+    2. On the **New property mapping** modal, select **SAML Property Mapping** and then click **Next**.
+    3. Define the required values. In the **Expression** field, define `User.Email` as `return request.user.email`.
+4. Click **Finish**.
+5. Create the property mapping for `User.Username`.
+    1. On the **Property Mappings** page, click **Create**.
+    2. On the **New property mapping** modal, select **SAML Property Mapping** and then click **Next**.
+    3. Define the required values. In the **Expression** field, define `User.Username` as `return request.user.username`.

+### Step 2. Create a new authentication provider
+
+1. Navigate to **Applications -> Providers** and then click **Create**.
+2. On the **New provider** modal, select **SAML Provider** and then click **Next**.

+    - **Authorization flow**: Authorize Application (`default-provider-authorization-implicit-consent`).
+    - **Protocol settings** define the following values:
+        - **ACS URL**: `https://_workspace-name_.slack.com/sso/saml`
+        - **Issuer**: `https://slack.com`.
+        - **Service Provider Binding**: select **Post**
+    - **Advanced protocol settings**
+        - **Signing Certificate**: select the appproriate certificate for Slack.
+        - **Property mappings**: Select the property mappings that you created in Step 1. You can leave the default property mappings and other settings.
+4. Click **Finish** to create the provider.
+
+### Step 3. Create a new application
+
+1. Navigate to **Applications -> Applications** and then click **Create**.
+2. Provide a name for the new application.
+3. Set the provider to the one you just created.
+4. Click **Create**.

+### Step 4. Configure Slack
+
+1. Log in to the Slack Admin Dashboard.
+2. Navigate to the **Configure SAML Authentication** page.

+    - **SAML 2.0 Endpoint (HTTP)**: copy/paste in the **SSO URL (Redirect)** URL from the provider that you created in authentik. **Example**: `https://_authentik.company_/applications/saml/slack/sso/binding/redirect/`
+    - **Identity Provider Issuer**: set to `https://slack.com`
+    - **Public Certificate**: add the certificate, which you can download from the authentik provider, under **Download signing certificate**.
+4. Optionally, configure the other settings and customize the Sign in button label.
+5. Click **Save**.
