Switch the CA SSO Authentication Scheme Type to HTML Form Template :


Vapp 14.0.x is Working as Designed. 

Identity Portal uses the wildly built in security to allow access to the Portal Admin UI. 

When sending basic auth credentials to the Portal wildfly, the application server will always try to validate these credentials against its internal file based user repository (where only the Portal Admin user is configured). 

This behavior cannot be changed in the Portal.

To support customer’s requirement, allowing end users to login into the Identity Portal via SSO with Radius Authentication 

(with basic authentication popup in a web browser) there is a workaround :


Setup a “Portal Radius Redirect page” on the SSO webagent and direct end users to browse to it (the page will auto redirect the users to the Portal after successful login with Radius). 

This redirect page will receive the basic auth headers, ignore them and redirect the user to the Portal page, this time without the headers. 


You will need to involve a SSO Administrator to accomplish this configuration. 

Here are the highlights of a setup used to achieve this: 


1. Under the SSO domain protecting the Portal realm define a new Realm (/Radius) for Radius authentication. 


2. Update Portal Domain Policy to have a new rule for the Radius Realm. 


3. Create an HTML page to act as an auto redirect (portal.html) – you would need to change the redirect URLs to fit your environment. 


Example : 



<html lang="en-US"> 


<meta charset="UTF-8"> 

<meta http-equiv="refresh" content="1; url="> 

<script type="text/javascript"> 

window.location.href= ""
