How do we get Firefox to use Integrated Authentication the way IE does?

Administration Authentication

Issue

When logging in to WorkflowGen directly on the WorkflowGen server in Firefox using the URL http://localhost/wfgen, there is a security error denying entry to the application.

Cause

WorkflowGen is a web-based application that can use IIS security to authenticate users attempting to log in to it. In some cases, Integrated Authentication is used so that users have a “single sign on” experience (IIS will request the Windows User login information to sign in to WorkflowGen).

IIS can use Integrated Authentication to log in to WorkflowGen, and by default IE has the ability to use these credentials (your Windows user account) However, to activate this feature in Firefox, you will need to make a small configuration change to how Firefox uses your Windows account.

Solution

To set up Firefox to use Integrated Authentication, follow the steps below:

  1. Open Firefox and enter about:config in the address bar.

  2. In the Filter, enter ntlm.

  3. Double-click network.automatic-ntlm-auth.trusted-uris and enter localhost, then press ENTER.
