    Mixed Authentication Support for Nintex App Studio

    Status: Validated

    QUESTION
    Does Nintex App Studio support Mixed Authentication for SharePoint with Forms Based Authentication (FBA)?
    ANSWER
    Nintex App Studio does not support Mixed Authentication for SharePoint out of the box. When a SharePoint environment has both Windows Authentication and Form Based Authentication configured, Nintex Mobile will only support Windows Authentication by default.

    However, you can use the following steps to put in place an IIS redirect which will allow Nintex App Studio to authenticate through FBA even when Windows Authentication is enabled:
    1. Enable FBA Access within Central Administration > Nintex Forms Management > Manage FBA Mobile Access.
      1. This can be done without Nintex Live being enabled, however to open Manage FBA Mobile Access you must navigate to the explicit URL: http://[CentralAdministrationURL]/_admin/NintexForms/MobileFBAManagement.aspx
    2. Configure a 302 redirect from "http://[SiteURL]/_vti_bin/NintexFormsServices/NfMobileAppService.svc/authenticate" to "http://[SiteURL]"
      1. Nintex Mobile will route to the FBA endpoint and users can sign into the Nintex Mobile app.
        1. Example: 
          http://MyTestingSite.contoso.com/extranet/_vti_bin/NintexFormsServices/NfMobileAppService.svc/authenticate

           redirects to: 
          http://MyTestingSite.contoso.com/extranet/

    The recommended approach to achieve the redirect is through an explicit URL redirect on the IIS Site. This can be done using Microsoft's URL rewrite tool: https://www.iis.net/downloads/microsoft/url-rewrite, and you the following configuration settings:
