Steps to reproduce the problem:
1. Windows 10 workstation – MS Edge (default web browser). IE11 and Google Chrome are offered as additional web browsers
2. Configure environment to use Enterprise Mode Site List (schema v2) for IE11 and MS Edge. The configure environment to use Chrome Legacy Browser Support.
3. Legacy web app - URL is https://epf.kp.org supports IE11 only.
Add “epf.kp.org” to Enterprise Mode Site List to open in IE11 in “default” document mode.
4. Legacy web app is setup to use Federated Access Management (FAM), SAML based, for authentication service. URL is https://signon.kp.org/.
“signon.kp.org” supports legacy and modern web browsers. Therefore, it is NOT added to the Enterprise Mode Site List.
5. Web apps that use FAM for authentication are setup to redirect (HTTP 302) the browser to FAM website for authentication purposes and on successful authentication to redirect (HTTP 302) back to requesting site.

A user opens Chrome to navigate to https://epf.kp.org.
1 Chrome performs a GET successfully. Then using LBS it sees that this URL is listed in EMIE Site List. Executes “iexplore.exe process to start IE11.
2. IE11 performs a GET successfully. The server responds an HTTP 302 with Location: https://signon.kp.org
3. IE11 performs a GET https://signon.kp.org successfully.
4. IE11 renders the login page where the user needs to enter username and password.
The user enters login credentials and clicks on “Sign On” button.

What is the expected behavior?
The site should continue to load in IE11 since primary site “epf.kp.org” is listed in EMIE Site List to open IE11

What went wrong?
IE11 closes and launches Chrome. Chrome performs a GET operation to https://signon.kp.org. 

Possible cause: LBS BHO launches Chrome because “signon.kp.org” doesn’t exist in the Enterprise Mode Site List to open in IE11

Did this work before? No
