There seems to be an error with getting the process image:

java.lang.NullPointerException
at org.activiti.image.impl.DefaultProcessDiagramCanvas.drawTask(DefaultProcessDiagramCanvas.java:659)

Can you upload your process xml so we can try and fix?

The behavior is same for all process XML. Same issue is shown for all process XML whether process is simple or complex.

Hmm that's odd .. cause the stacktrace clearly shows

java.lang.NullPointerException
at org.activiti.image.impl.DefaultProcessDiagramCanvas.drawTask(DefaultProcessDiagramCanvas.java:659)

And it doesn't happen without ldap?
