SAML authentication with Microsoft Entra ID

With SAML (Security Assertion Markup Language) enabled, you can authenticate users in Cube through Microsoft Entra ID (formerly Azure Active Directory), allowing your team to access Cube using single sign-on.

<Note>

Available on Enterprise plan.

Prerequisites

Before proceeding, ensure you have the following:

• Admin permissions in Cube.
• Sufficient permissions in Microsoft Entra to create and configure Enterprise Applications.

Enable SAML in Cube

First, enable SAML authentication in Cube:

1. In Cube, navigate to Admin → Settings.
2. On the Authentication & SSO tab, enable the SAML toggle.
3. Take note of the Single Sign-On URL and Audience values — you'll need them when configuring the Enterprise Application in Entra.

Create an Enterprise Application in Entra

1. Sign in to the Microsoft Entra admin center.
2. Go to Enterprise Applications and click New application.
3. Select Create your own application.
4. Give it a name and choose a non-gallery application, then click Create.

Configure SAML in Entra

1. In your new Enterprise Application, go to the Single sign-on section and select SAML.
2. In the Basic SAML Configuration section, enter the following:
   • Entity ID — Use the Single Sign-On URL value from Cube.
   • Reply URL — Use the Single Sign-On URL value from Cube.
3. Go to Attributes & Claims → Edit → Advanced settings and set the audience claim override to the Audience value from Cube.
4. Go to SAML Certificates → Edit and select Sign SAML response and assertion for the Signing Option.
5. Download the Federation Metadata XML file — you'll need it when completing the Cube configuration.

Configure attribute mappings

Before returning to Cube, configure the SAML claims Entra sends during login. Cube uses these claims to identify the user and map optional attributes such as display name.

Create explicit SAML claims in Entra with the names Cube uses by default.

1. In your Entra Enterprise Application, go to Single sign-on → Attributes & Claims.
2. Add the following claims. Leave Namespace blank for each claim:
   • Email — Set Name to email and Source attribute to user.userprincipalname or user.mail.
   • Display name — Set Name to name and Source attribute to user.displayname.

If you plan to map Cube roles based on Entra group membership (see Map roles by group below), also add a group claim:

1. Still in Attributes & Claims, click Add a group claim.

2. Choose which groups to include (e.g. Security groups or Groups assigned to the application) and pick a Source attribute for the group name. For most setups, select sAMAccountName or Cloud-only group display names so the assertion carries human-readable group names that match the IdP group name values you'll configure in Cube Cloud.

3. Save the claim.

   Cube reads Entra's canonical groups claim URL (http://schemas.microsoft.com/ws/2008/06/identity/claims/groups) automatically, so no further attribute renaming is required on the Entra side.

Complete configuration in Cube

Return to the SAML configuration page in Cube and provide the identity provider details. You can do this in one of two ways:

Option A: Upload metadata file

1. In the Import IdP Metadata section, click Upload Metadata File.
2. Select the Federation Metadata XML file you downloaded from Entra. This will automatically populate the Entity ID / Issuer, SSO (Sign on) URL, and Certificate fields.

Option B: Enter details manually

If you prefer to configure the fields manually, enter the following values from the Entra Single sign-on page:

• Entity ID / Issuer — Use the Microsoft Entra Identifier value.
• SSO (Sign on) URL — Use the Login URL value.
• Certificate — Paste the Base64-encoded certificate from the SAML Certificates section.

In both options, also configure the following setting:

• Auto-provision new users — When enabled, users are automatically created in Cube on their first login via this SAML provider. Enable this if you want to provision users only when they first access Cube and you are not using SCIM provisioning. New users receive the Viewer role by default; see Default role for new users to choose a different role.

Default role for new users

Auto-provisioned users — both via SAML and via SCIM — receive the Viewer role by default. To assign a different role, expand the Advanced section of the SAML configuration form and pick from Default role for new users:

• Developer, Explorer, or Viewer — Cube's default roles.
• Any custom role defined in your account, listed below the divider.

The selected role applies only when a user is first created during provisioning. Existing users are not modified on subsequent SSO logins or SCIM updates.

<Info>

Admin status is not assignable through this picker — Admin is controlled separately. To grant admin permissions, update the user's role manually under Admin → Users.

</Info> <Warning>

If the selected role is later renamed or deleted, new users will fall back to the Viewer role until you pick a valid role here. The Viewer fallback applies whenever the configured default cannot be resolved — whether that's because no default is set or the configured role no longer exists.

</Warning>

Map roles by group

For finer-grained role assignment, enable Map roles by group in the Advanced Settings section to assign Cube roles based on a user's Entra group memberships.

To configure group-based role mapping:

1. Make sure Entra sends a group claim on the SAML assertion. See the group-claim step in Configure attribute mappings.
2. In the SAML configuration form in Cube, expand Advanced Settings.
3. (Optional) Under SAML attribute customization, set the Groups attribute to the simple name of the SAML attribute carrying group memberships. Defaults to groups. Cube also reads Entra's canonical groups claim URL automatically, so the default usually works out of the box.
4. Enable the Map roles by group toggle.
5. Click Add group mapping and create one entry per group you want to map:
   • IdP group name — the group display name as it appears in the assertion (case-insensitive). With Source attribute set to sAMAccountName or Cloud-only group display names, this is the human-readable group name. If you left the default (group object ID), use the GUID instead.
   • Cube role — pick a default or custom role.

For SAML SSO, group mappings are evaluated only when a new user is auto-provisioned on first login. If any matching group resolves to a Cube role, those roles are assigned to the new user instead of the configured default role. The default role is used as a fallback when no IdP group matches (or when the mapped Cube roles no longer exist). Existing users' role assignments are never modified by subsequent logins.

The same mapping is also applied by SCIM when group memberships are pushed, so a single configuration drives both SAML SSO and SCIM group sync.

Assign users

Make sure the new Enterprise Application is assigned to the relevant users or groups in Entra before testing.

Test the integration

1. In the Entra Single sign-on section, click Test to verify the SAML integration works for your Cube account.
2. Alternatively, copy the Single Sign-On URL from Cube, open it in a new browser tab, and verify you are redirected to Entra for authentication and then back to Cube.
