Pre-Installation Tasks

Before you can install Digipass Authentication for OWA Basic, there are several tasks you need to complete.

Install the authentication server

You need to install an authentication server on the network before Digipass Authentication for OWA Basic is installed. See Software requirements for compatible servers and Configure the authentication server for configuration recommendations.

If the users are Active Directory users on a Windows platform, it is recommended that the Use Windows user name resolution feature on the authentication server is enabled. This uses Windows functions to identify user IDs as Windows user accounts, including the domain to which the account belongs.

This feature is not available on Linux platforms or OneSpan Authentication Server Appliance/OneSpan Authentication Server Virtual Appliance.

If the Use Windows user name resolution feature is disabled, it is essential that users always use the same logon name. If they try to log on with a different form of their Windows account name, their logon will be rejected, unless a second OAS user account has been created.

Administrator privileges

To install Digipass Authentication for OWA Basic you need to be logged on with a user that has local administrator privileges.

Ensure that Internet Information Services (IIS) and Microsoft Exchange are operational

Ensure Microsoft Internet Information Services (IIS) and Microsoft Exchange are installed and working correctly. Digipass Authentication for OWA Basic must be installed on the machine where IIS and Outlook Web Access/Outlook on the web are running.
