      1. Configure LDAP integration with PAM (https://access.redhat.com/solutions/4033931)
      2. Configure the LDAP base DN incorrectly intentionally - so later it will not return correct user data
      2. Create some process instances with human tasks
      3. In "Task Inbox" page in business-central, trigger the LDAP search operation via changing the "Status" filter on left side , receive the error message (attaching screenshot)
      4. Go to kie-server and check the server.log, find stacktraces like below

      NullPointerException will be thrown in line#127 in LDAPUserGroupCallbackImpl.java when LDAP search return unexpected data .

      A proper error message is preferred (rather than 500 error code with "unexpected error: null" message)
