IAC : authentication not being executed
SA-24864
Summary
User has two different applications on one server and those two applications are not dependent on each other. With their latest release, in Application1, they are trying to load a screen from Application2 using IAC. They observed that during this the IAC authentication is not being executed at all. They are facing display error in the Application 1 screen.
Error Messages
- IAC authentication is not being executed at all
- In application 1 screen, we are seeing display error message.
Steps to Reproduce
From Application 1 screen, try to load a screen from Application 2 using IAC gadget code.
Root Cause
User was not using the gateway in their setup. They are usingthe gateway url as pega.web.config.gatewayURL= "/prweb/IAC/";
However in their gadget code they are setting the systemid parameter as pega.web.config.systemID = <Gateway system id name>
Note: If both of the applications reside on the same server and the user first logs into the server and launches application 1 which displays Application 2 through IAC gadget code, then the authentication won't be triggered. Because the session id is generated and remains same when user first logs into the server. This is expected behavior.
Resolution
Remove the parameterr "pega.web.config.systemID" from the gadget code when not using the gateway.
