Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty - Security * **************************************************************** * PROBLEM DESCRIPTION: Liberty AdminCenter login panel does * * not show logos, images, etc, when a TAI * * with invokeForUnprotectedURI=true is * * used * **************************************************************** * RECOMMENDATION: * **************************************************************** When a custom trust association interceptor (TAI) is configured with the invokeForUnprotectedURI=true flag, Liberty is supposed to call the custom TAI when an unprotected URI is requested. Instead, Liberty incorrectly went on to call system TAIs such as Saml, Oauth, and OIDC. As a result, AdminCenter login panel GUI elements were denied access by the system TAI, preventing them from rendering on the page.
Problem conclusion
The authentication logic has been updated to perform the expected behavior. The fix for this APAR is currently targeted for inclusion in fix pack 19.0.0.4. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
If custom TAI allows, AdminCenter would show a simple userid and password entry fields so user can perform login. After successful login, the user may need to type in the desired URI in the browser to get to the panel.
