The MS-OFBA protocol provides a mechanism for native MS Office applications (e.g. Word, Excel, etc.) to establish an authenticated HTTP session with an MS-SharePoint server protected by the Airlock Secure Access Hub.

In combination with Airlock Gateway (WAF), Airlock IAM supports HTTP-based authentication via MS-OFBA. The IAM authentication process for MS-OFBA has been designed as a one-shot authentication flow, using the MS-OFBA One-Shot Target Application.
