Single Sign-On Configuration

Ivanti Neurons for MDM enables Extensible Single Sign-On (SSO) with the Extensible SSO and Extensible SSO Kerberos configurations. The implementation requires an app extension, such as Microsoft Authenticator, from the identity provider. With an Extensible SSO implementation, users need to only authenticate once when accessing enterprise resources. Users are not prompted to authenticate for subsequent logins. For information about setup information for the intended identity provider, see Configure Identity Provider.

This section contains the following topics:

Single sign-on account settings

Applicable to:

  • iOS 7.0 through the most recently released version as supported by Ivanti Neurons for MDM.

  • visionOS 1.1 through the most recently released version as supported by by Ivanti Neurons for MDM.

Use the following settings to configure Kerberos-based enterprise SSO for any managed app and Apple Safari browser on iOS devices.

This configuration requires Tunnel and Sentry. For more information, see "Setting up single sign-on with Kerberos" in the Tunnel for iOS Guide.
