One-shot target application configuration for MS-OFBA

This article shows how to configure a one-shot target application for usage with MS-OFBA.

Note that this article covers only part of the MS-OFBA setup. Please refer to MS-OFBA Configuration in Airlock Gateway and Airlock IAM for all configuration steps.

The one-shot target application configuration takes care of handling the MS-OFBA-specific HTTP protocol parts and it redirects the web browser built into MS-Office applications (such as Word) to the login screen.

Prerequisites

  • Airlock Gateway must be configured to redirect the authentication request to IAM.
  • SharePoint must be configured as back-end in Airlock Gateway.

Limited Loginapp features available

Note that the MS-Office applications (e.g. Word) use outdated browser libraries (IE11 or IE8) that are not compatible with the AIrlock IAM Loginapp UI.

The Loginapp UI provides a very limited set of features available for MS-OFBA by offering a separate Loginapp front-end written in JavaScript. Currently, only username password authentication and mTAN as the second factor are supported.

If Microsoft does not update to newer browser libraries, MS-OFBA support may be removed from Airlock IAM in future versions.

    Loginapp >> One-Shot Authentication
