Tech Tip : CA Single Sign-On : IWA authchain not working with domain joined machine when not in network

Discussion created by Patrick-Dussault Employee on Sep 5, 2018

Issue:


We're running CA Access Gateway (SPS), when resource is protected with
"authentication chain" Authentication Scheme, if the first IWA
Authentication fails, the browser doesn't get the HTML Form
Authentication Scheme, but the popup to login. If we cancel this
Pop-Up, then the browser receives return code 403.

But reading the documentation, if the IWA fails, then the browser
should receive the HTML Form to authenticate instead :

IWA Fallback to Forms

 

If IWA/Windows authentication scheme fails, CA SSO falls back to
Forms-based authentication scheme. This fallback process helps you
combine an IWA authentication scheme and a form/HTML authentication
scheme as the new authentication chain.

 

How can we fix this ?

 

Environment:

 

CA Access Gateway (SPS) 12.7

 

Resolution:

 

Upgrade CA Access Gateway (SPS) to the next CR of 12.7
