Enabling Entra ID SSO Connections with Your OVHcloud Account – Support Guides

Learn how to associate your OVHcloud account with an external Entra ID.

You can use Single Sign-On (SSO) to connect to your OVHcloud account. To enable these connections, your account and your Entra ID have to be configured using SAML (Security Assertion Markup Language) authentications.

Requirements

belong to the Application Administrator and User Administrator roles of an Entra ID service

Instructions

For a service provider (i.e. your OVHcloud account) to establish an SSO connection with an identity provider (i.e. your Entra ID), the essential part is to establish a mutual trust relationship by registering the SSO connection in both services.

Entra ID Users and Groups

Your Entra ID acts as your identity provider. Authentication requests by your OVHcloud account will only be accepted if it is declared as a trusted party first.

Let's focus for a moment on the identities on the identity provider side.

Entra ID Users

To start, go to your Entra ID dashboard.

Then click Users from the left-hand menu.

Create as many users as you need, or you can just check your users by clicking on them.

For this example, the user John Smith will be used.

When an SSO authentication is performed, John Smith's identity will be provided by Entra ID to the OVHcloud account. However, it is necessary that this identity contains at least one group. If no group exists, let's look at how to create one to add John Smith to it.

Entra ID Groups

Click on Groups from the left-hand menu.

Click on New group in the top menu, and fill in all the necessary information.

For this example, the group manager@ovhcloudsaml will be used.

Click on the Create button to display all information about this group.

Now, users who will be used for SSO authentication must be added to a group.

In this example, let's link the user John Smith with the group manager@ovhcloudsaml.

In the selected group interface, click on Members from the left-hand menu, then click Add members in the top menu.

Select the user to be added to this group, then click on the Select button.

Now we have a user assigned to a group.

To perform SSO authentications, an Entra ID application must be created.

SSO must be configured on this application.

Entra ID applications

First of all, it is necessary to create an application if one does not yet exist.

Create an Entra ID application

Click on Enterprise applications from the left-hand menu.

Click on New application in the top menu.

Click on Create your own application in the top menu.

Select the Integrate any other application you don't find in the gallery (Non-gallery) option, and click on the Create button.

The details of the application will then be displayed.

The Entra ID application is now created. Users who want to perform SSO authentications via this application must now be added to it.

Entra ID application - User assignment

In order for a user to perform an SSO authentication from an Entra ID application, it must be added to that application. It is therefore shown here how to add a user to an Entra ID application.

However, it is better to add a user group instead of users if you have Entra ID Premium.

Click on Users and groups from the left-hand menu, then click Add user/group in the top menu.

Click then on the Users section, select the user to add to the application, and click on the Select button.

The application is created, a user has been assigned, and all that remains is to set up the SSO via SAML.

Click Assign to add the user assignment.

Entra ID application SSO

Get back to the overview via the Overview button from the left-hand menu, then click on the Set up single sign on section.

Click on the SAML section.

Click on Upload metadata file in the top menu.

Click on the Select a file icon button, select the OVHcloud Service Provider metadata file, and click on the Add button.

You can obtain the US region metadata file via the following link: https://us.ovhcloud.com/auth/sso/saml/sp/metadata.xml

The SAML configuration will be displayed. The Entity ID and URL are: https://us.ovhcloud.com/auth/

Click Save and close the window.

In the Attributes & Claims section, click on the Edit button.

You now need to add a UPN (User Principal Name) attribute to SAML info, in order to inform OVHcloud about the user's email. This step is mandatory.

Click on Add a new claim in the top menu.

Fill in the Name field with http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn.

Fill in the Source attribute field with user.mail.

Click on Save.

Now let's declare the attribute for the user group.

Click on Add a group claim in the top menu.

Select Security groups, Group ID from the Source attribute, and click on the Save button.

The groups claim should now appear in the list.

Copy and save the Claim name value somewhere (i.e a notepad), it will be necessary later.

In the SAML Certificates section, copy the App Federation Metadata Url field value.

Establishing OVHcloud account trust and configuring the connection

Establish OVHcloud trust

Adding your Entra ID application as a trusted identity provider is done in the OVHcloud Control Panel where you can provide the identity provider metadata.

Click your name and then your initials.
Select Identity and Access Management (IAM) from the left-hand menu.
Click the Identities tab to access local users management.

Click on the SSO connection button.

Fill in the Group attribute name field with the Entra ID application groups Claim name value saved before.

Fill in the XML metadata of your Entra ID application from the file saved before. Click on Confirm.

You can keep local users by ticking the Keep active OVHcloud users box.

The trust of your Entra ID application as the identity provider is thus established but you still have to add groups to your OVHcloud account.

NOTE: If you try to connect at this stage via SSO, you will probably receive a Not in valid groups error message.

That is because your OVHcloud account checks if the authenticating user belongs to a group that actually exists on the account.

To resolve this, check the "Group" attribute that your Entra ID application returns: the Object Id field.

OVHcloud groups declaration

Add it by clicking on the Declare a group.

Fill in the fields, then click on the Confirm button.

The created group should appear on the list.

Connect via SSO

On the OVHcloud login page, enter your customer code followed by /idp without entering a password, and click the Login button.

You are then redirected to your Entra ID application login page. Select Use another account.

Enter the Entra ID application user email and click on the Next button.

Enter the Entra ID application user password and click on the Sign In button.

You are now logged in with the same customer code, but via your Active Directory user and using your Entra ID application SSO.

If your email does not appear below Connected via SSO, you have not configured the UPN attribute properly, and some of the features will not work correctly.
