The customer needs to use Radius Authentication Scheme instead of HTML Form with CA SSO (Aka CA SiteMinder).
CA Identity Suite documentation customer is guided to Switch the CA SSO Authentication Scheme Type to the HTML Form Template.
How can the customer do this?
Switch the CA SSO Authentication Scheme Type to HTML Form Template
VApp 14.0.x is Working as Designed.
Identity Portal uses the Wildfly, built -n security to allow access to the Portal Admin user interface.
When sending basic auth credentials to the Portal wildfly, the application server always tries 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 the Portal.
To allow end users to log into the CA Identity Portal via CA SSO with Radius Authentication
(with basic authentication popup in a web browser) there is a workaround.
You will need to involve a SSO Administrator to accomplish this configuration.
Here are the highlights of a setup used to achieve this configuration:
1. Under the CA 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.
For example :
<meta http-equiv="refresh" content="1; url=https://sso126.ca.com/sigma/">
<title>Page Redirection </title>
