Microsoft Conditional Access Custom Controls integration guide

Microsoft Conditional Access is a feature of their Microsoft Entra ID (formerly Azure AD) service. This feature allows organizations to define and enforce policies that evaluate the conditions under which a user is allowed to access company resources. This ensures that access is only granted under the right conditions and to the right people.

Microsoft has a function to Conditional Access called custom controls. Custom controls allow third-party integration into Conditional Access. This process involves having a registered application by the third party to be allowed globally by Microsoft and then providing OpenID Connect (OIDC) endpoints for use by the Microsoft Entra ID customer to call out to the third party's authorization process.

Note

For the Microsoft External Access Method (EAM) integration in the Identity Platform, see Microsoft Conditional Access External Authentication Method (EAM) integration guide.Microsoft Conditional Access External Authentication Method (EAM) integration guide

Process

To set up a Conditional Access integration in the Identity Platform, the following is an outline of tasks to complete.

Applies to

Applies to the following Identity Platform releases and hotfixes:

  • Identity Platform 24.04

  • Identity Platform 23.07, requires hotfix 23.07-1 or later

  • Identity Platform 22.12, requires hotfix 22.12-4 or later

Have a configured OIDC application

Have an OpenID Connect (OIDC) application for the Conditional Access configuration. See Configure OIDC application.

Contact Support to configure the Conditional Access integration

After you've configured an OIDC application, contact Support and open a support ticket with "Conditional Access" in the subject line. Provide the first two items:

  • Client ID. In the Advanced Settings > Post Authentication tab for the OIDC application, copy and provide the Client ID.

  • Public URL. In the Advanced Settings > Post Authentication tab for the OIDC application, copy and provide the public URL of the OIDC application.

  • Then, you will receive a JSON file from Support. You will need this for the task in Configure Microsoft Custom Control.

Configure OIDC application

In the Identity Platform, have an OIDC application configured for use with Microsoft Conditional Access.

The Identity Platform with this hotfix will retrieve the user ID from Microsoft for this request. Microsoft sends a HTTP POST with the OIDC parameters and an additional parameter called id_token_hint. This parameter includes a JSON web token (JWT) and a number of claims, including the unique ID for the user and their user principal name (UPN). The Identity Platform must obtain that information and validate the JSON Web Token (JWT).

For the OIDC application, configure the settings as described next in each of the sub sections.

Test connection

Make sure that https://login.microsoftonline.com/common/discovery/keys is accessible from the SecureAuth server.

Data tab settings

  1. In Advanced Settings, select the Data tab.

  2. Create a connection based on the data store type, such as Active Directory or SQL Server.

    Make sure the searchFilter field is set to (|(samAccountName=%v)(userPrincipalName=%v)) to allow to allow this application a dual lookup filter to support the UPN format provided by the inbound Microsoft request.

  3. In the Profile Fields section, set the following Aux ID value:

    Aux ID 2

    Set to otherLoginWorkstations.

    You will need this on the Post Authentication tab for the Consent Storage Attribute field.

    ms_conditional_auxid2.png

  4. In the Global Aux Fields section, set the following Global Aux ID value:

    Global Aux ID 1

    Set to Validated.

    You will need to set this Aux ID on the Post Authentication tab for the Custom Claims.

  3. In the User ID Mapping section, set the following values:

    User ID Mapping

    Set to Authenticated User ID.

    Name ID Format

    Set to urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified.

    This must be a public-facing and have a valid SSL certificate.

    Signing Algorithm

    Set to one of the following values:

    • RSA SHA256 (RS256) – An asymmetric algorithm, which means it uses a public/private key pair. SecureAuth uses the private key for signing and provides you with the public key to use to validate the signature.

    • HMAC SHA256 (HS256) – A symmetric algorithm, which means one secret key is shared between SecureAuth and the end-user. The same key is used to create the signature and to validate it. This key must be kept secret at all times.

    Signing Cert

    Set to any certificate that is a private key readable by SecureAuth Identity Platform.

    Do not use wild cards in a certificate.

    Auto Accept User Consent

    Set to True to provide a clean user experience.

    Enable User Consent Storage

    Set to True to provide a clean user experience and to enable check session endpoints.

    Consent Storage Attribute

    Set to the AUX ID 2 value that was mapped earlier on the Data tab to a string attribute.

    For example, otherLoginWorkstations.

    Authorization Code Lifetime

    Access Token Lifetime

    Refresh Token Lifetime

    Leave the default settings as is.
