To enable clients to log in through OneLogin in Zluri, you must create Zluri as a SAML app and add an Email parameter. Here are step-by-step instructions to follow:

1. Log in to your OneLogin account and navigate to the SAML app configuration.

2. Locate the Zluri SAML app and click on it. If the Zluri SAML App is unavailable in the Apps Catalog of OneLogin, you can contact the support team or create a custom app for Zluri SAML.

3. To create a Custom app:
   A. Navigate to Applications > Applications > Add Apps in the OneLogin administrator dashboard. Search for SAML Custom Connector (Advanced) and select the first result from the search results.
   
   B. Rename the "Display Name," add the "Icons" & "Description" in the successive field.
    And click save.

4. Look for the "Parameters" section and click on it.

5. Click the plus icon or the "Add Parameter" button to add a new parameter.
   

6. In the "Field Name" section, enter the following value: "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress". This value represents the email address field in the SAML assertion.
   

7. Check the "Include in SAML assertion" box for this parameter.

8. Click "Save" to save the new parameter.

9. Find the newly created parameter in the list and click on it.

10. Set the "Value" field to "email" (without quotes). This value tells the SAML app to include the email address in the SAML assertion.
    
    
    

11. Click "Save" to save the parameter with the assigned value.
    

           The application will now appear in the applications.

After following these steps, it would be advisable to test the SAML app to ensure everything works.
