Issue:

After configuring Identity Manager on multiple JBoss/Wildfly nodes behind a webserver using the Jakarta plug in logged in users will get the following error:

08:29:20,681 DEBUG [ims.ui] (ajp-/0.0.0.0:8009-2) Creating task session for not public task without valid User DN
: com.netegrity.ims.exception.IMSException:
Creating task session for not public task without valid User DN

Environment:
Identity Manager on JBoss or WildflyIIS or Apache WebServer using Jakarta to connect to the application server
Cause:

This error is indicative of the session being lost bouncing between the JBoss/Wildfly nodes.

Resolution:

Modify the workers.properties file to set the sticky session. This forces Jakarta to keep sessions on the same node for all requests for a particular client.

worker.router.sticky_session=true
