Microsoft Entra SSO integration with SecureTransport

In this article, you learn how to integrate SecureTransport with Microsoft Entra ID. SecureTransport is a high scalable and resilient multi-protocol MFT gateway, with fault-tolerance and high availability to meet all critical file transfer needs of any small or large organization. When you integrate SecureTransport with Microsoft Entra ID, you can:

• Control in Microsoft Entra ID who has access to SecureTransport.
• Enable your users to be automatically signed-in to SecureTransport with their Microsoft Entra accounts.
• Manage your accounts in one central location.

You configure and test Microsoft Entra single sign-on for SecureTransport in a test environment. SecureTransport supports SP initiated single sign-on.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

Prerequisites

To integrate Microsoft Entra ID with SecureTransport, you need:

• A Microsoft Entra user account. If you don't already have one, you can Create an account for free.
• One of the following roles: Application Administrator, Cloud Application Administrator, or Application Owner.
• A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
• SecureTransport single sign-on (SSO) enabled subscription.

Add application and assign a test user

Before you begin the process of configuring single sign-on, you need to add the SecureTransport application from the Microsoft Entra gallery. You need a test user account to assign to the application and test the single sign-on configuration.

Add SecureTransport from the Microsoft Entra gallery

Add SecureTransport from the Microsoft Entra application gallery to configure single sign-on with SecureTransport. For more information on how to add application from the gallery, see the Quickstart: Add application from the gallery.

Create and assign Microsoft Entra test user

Follow the guidelines in the create and assign a user account article to create a test user account called B.Simon.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, and assign roles. The wizard also provides a link to the single sign-on configuration pane. Learn more about Microsoft 365 wizards..

Configure Microsoft Entra SSO

Complete the following steps to enable Microsoft Entra single sign-on.

1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

2. Browse to Identity > Applications > Enterprise applications > SecureTransport > Single sign-on.

3. On the Select a single sign-on method page, select SAML.

4. On the Set up single sign-on with SAML page, select the pencil icon for Basic SAML Configuration to edit the settings.

   

5. On the Basic SAML Configuration section, perform the following steps:

   a. In the Identifier textbox, type one of the following values:

   User type	value
   Admin	st.sso.admin
   End-user	st.sso.enduser

   b. In the Reply URL textbox, type a URL using one of the following patterns:

   User type	URL
   Admin	https://<SecureTransport_Address>:<PORT>/saml2/sso/post/j_security_check
   End-user	https://<SecureTransport_Address>:<PORT>/saml2/sso/post

   c. In the Sign on URL textbox, type a URL using one of the following patterns:

   User type	URL
   Admin	https://<SecureTransport_Address>:<PORT>
   End-user	https://<SecureTransport_Address>:<PORT>

   Note

   These values are not real. Update these values with the actual Reply URL and Sign on URL. Contact SecureTransport Client support team to get these values. You can also refer to the patterns shown in the Basic SAML Configuration section.

6. Your SecureTransport application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows an example for this. The default value of Unique User Identifier is user.userprincipalname but SecureTransport expects this to be mapped with the user's display name. For that you can use user.displayname attribute from the list or use the appropriate attribute value based on your organization configuration.

   

7. On the Set-up single sign-on with SAML page, in the SAML Signing Certificate section, find Federation Metadata XML and select Download to download the certificate and save it on your computer.

   

8. On the Set up SecureTransport section, copy the appropriate URL(s) based on your requirement.

   

Configure SecureTransport SSO

To configure single sign-on on SecureTransport side, you need to send the downloaded Federation Metadata XML and appropriate copied URLs from the application configuration to SecureTransport support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create SecureTransport test user

In this section, you create a user called Britta Simon at SecureTransport. Work with SecureTransport support team to add the users in the SecureTransport platform. Users must be created and activated before you use single sign-on.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

• Click on Test this application, this will redirect to SecureTransport Sign-on URL where you can initiate the login flow.

• Go to SecureTransport Sign-on URL directly and initiate the login flow from there.

• You can use Microsoft My Apps. When you click the SecureTransport tile in the My Apps, this will redirect to SecureTransport Sign-on URL. For more information, see Microsoft Entra My Apps.

Next steps

Once you configure SecureTransport you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Cloud App Security.
