Hi,
I am new to JBPM and I am using JBPM 5.1 for building an Application for Workflow. I am trying to use my own User Management like LDAP for the application. For that, I have downloaded SNAPSHOT of jBPM human-task 5.2 module (jbpm-human-task-5.2.0-20111010.064239-423.jar) and I have implemented Interface UserGroupCallback and I have also set the System property "jbpm.usergroup.callback" with the Implemented class.
However, I was not able to assign a user/human task to non-existing user in jBPM server (i.e., I was trying to assign a task to user who existing in LDAP but not in jBPM). I got the following error in jBPM server:

I am using Java 1.6 and OS is Ubuntu 10.10. Could someone please tell me what I am missing here? Do I need to wait for stable version of jBPM 5.2 for implementing my own User Management like LDAP?
Any help is much appreciated.
Thanks,
Hemaraj
