Duo Security is a SaaS authentication provider. This document will explain how to use Gluu's Duo interception script to configure the Gluu Server for a two-step authentication process with username and password as the first step, and Duo as the second step.
In order to use this authentication mechanism your organization will need a Duo account and users will need to download the Duo mobile app.
- A Gluu Server (installation instructions);
- Duo interception script (included in the default Gluu Server distribution);
- An account with Duo Security.
There are a few properties in the Duo Security authentication script:
|duo_creds_file||Mandatory||Path to ikey, skey, akey||/etc/certs/duo_creds.json|
|duo_host||Mandatory||URL of the Duo API Server||api-random.duosecurity.com|
|audit_attribute||Optional||Attribute to determine user group||memberOf|
|duo_group||Optional||Attribute to enable Duo for specific user||memberOf|
|audit_group||Optional||Notify administrator via email upon user login||memberOf|
