I’m trying to setup Duo to protect a website using the Web v2 SDK, and pretty much have it working. However, due to the framework that is being used, I have to setup the duo iframe within the JSP and have used the data-host, data-sig-request and data-submit_callback attributes.
Duo Authentication is working correctly, but the callback function is not being called. Debugging the Duo-Web-v2.js code and it looks like the submitCallback variable is only set during the init() function, and then only from the options, not the data- attributes. The data-attributes are being populated within the ready() function, but at no point does it retrieve the data-submit_callback
Am I missing something, or is the data-submit_callback attribute, although documented, not supported?
