Tutorial: Azure Active Directory integration with Trello

In this tutorial, you learn how to integrate Trello with Azure Active Directory (Azure AD).

Integrating Trello with Azure AD provides you with the following benefits:

  • You can control in Azure AD who has access to Trello.
  • You can enable your users to automatically get signed-on to Trello (Single Sign-On) with their Azure AD accounts.
  • You can manage your accounts in one central location - the Azure portal.

If you want to know more details about SaaS app integration with Azure AD, see what is application access and single sign-on with Azure Active Directory.

Prerequisites

To configure Azure AD integration with Trello, you need the following items:

  • An Azure AD subscription
  • A Trello single-sign on enabled subscription

Note

To test the steps in this tutorial, we do not recommend using a production environment.

To test the steps in this tutorial, you should follow these recommendations:

  • Do not use your production environment, unless it is necessary.
  • If you don't have an Azure AD trial environment, you can get a one-month trial.

Scenario description

In this tutorial, you test Azure AD single sign-on in a test environment. The scenario outlined in this tutorial consists of two main building blocks:

  1. Adding Trello from the gallery
  2. Configuring and testing Azure AD single sign-on

To configure the integration of Trello into Azure AD, you need to add Trello from the gallery to your list of managed SaaS apps.

To add Trello from the gallery, perform the following steps:

  1. In the Azure portal, on the left navigation panel, click Azure Active Directory icon.

    The Azure Active Directory button

  2. Navigate to Enterprise applications. Then go to All applications.

    The Enterprise applications blade

  3. To add new application, click New application button on the top of dialog.

    The New application button

  4. In the search box, type Trello, select Trello from result panel then click Add button to add the application.

    Trello in the results list

Configure and test Azure AD single sign-on

In this section, you configure and test Azure AD single sign-on with Trello based on a test user called "Britta Simon".

For single sign-on to work, Azure AD needs to know what the counterpart user in Trello is to a user in Azure AD. In other words, a link relationship between an Azure AD user and the related user in Trello needs to be established.

In Trello, assign the value of the user name in Azure AD as the value of the Username to establish the link relationship.

To configure and test Azure AD single sign-on with Trello, you need to complete the following building blocks:

  1. Configure Azure AD Single Sign-On - to enable your users to use this feature.
  2. Create an Azure AD test user - to test Azure AD single sign-on with Britta Simon.
  3. Create a Trello test user - to have a counterpart of Britta Simon in Trello that is linked to the Azure AD representation of user.
  4. Assign the Azure AD test user - to enable Britta Simon to use Azure AD single sign-on.
  5. Test single sign-on - to verify whether the configuration works.

Configure Azure AD single sign-on

In this section, you enable Azure AD single sign-on in the Azure portal and configure single sign-on in your Trello application.

Note

You should get the <enterprise> slug from Trello. If you don't have the slug value, contact Trello support team to get the slug for you enterprise.

To configure Azure AD single sign-on with Trello, perform the following steps:

  1. In the Azure portal, on the Trello application integration page, click Single sign-on.

    Configure single sign-on link

  2. On the Single sign-on dialog, select Mode as SAML-based Sign-on to enable single sign-on.

    Single sign-on dialog box

  3. On the Trello Domain and URLs section, if you wish to configure the application in IDP initiated mode, perform the following steps:

    Trello Domain and URLs single sign-on information

    a. In the Identifier textbox, type the following URL: https://trello.com/auth/saml/metadata

    b. In the Reply URL textbox, type a URL using the following pattern: https://trello.com/auth/saml/consume/<enterprise>

  4. If you wish to configure the application in SP initiated mode, perform the following steps:

    Trello Domain and URLs single sign-on information

    a. Check Show advanced URL settings.

    b. In the Sign-on URL textbox, type a URL using the following pattern: https://trello.com/auth/saml/login/<enterprise>

  5. Trello application expects the SAML assertions to contain specific attributes. Configure the following attributes for this application. You can manage the values of these attributes from the "User Attributes" of the application. The following screenshot shows an example for this.

    Configure Single Sign-On

  6. On the SAML token attributes dialog, for each row shown in the table below, perform the following steps:

    Attribute Name Attribute Value
    User.Email user.mail
    User.FirstName user.givenname
    User.LastName user.surname

    a. Click Add attribute to open the Add Attribute dialog.

    Configure Single Sign-On

    Configure Single Sign-On

    b. In the Name textbox, type the attribute name shown for that row.

    c. From the Value list, type the attribute value shown for that row.

    d. Click Ok.

  7. On the SAML Signing Certificate section, click Certificate (Base64) and then save the metadata file on your computer.

    The Certificate download link

  8. Click Save button.

    Configure Single Sign-On Save button

  9. On the Trello Configuration section, click Configure Trello to open Configure sign-on window. Copy the SAML Single Sign-On Service URL from the Quick Reference section.

    Trello Configuration

  10. To configure single sign-on on Trello side, you need to go to the Trello enterprise SSO configuration page to send the downloaded Certificate (Base64) and SAML Single Sign-On Service URL to Trello support team. They set this setting to have the SAML SSO connection set properly on both sides.

Tip

You can now read a concise version of these instructions inside the Azure portal, while you are setting up the app! After adding this app from the Active Directory > Enterprise Applications section, simply click the Single Sign-On tab and access the embedded documentation through the Configuration section at the bottom. You can read more about the embedded documentation feature here: Azure AD embedded documentation
