Users & Groups links in activit explorer throwing error

[penusila611621]

I have integrated Activit 5.13 with LDAP and able to login into activiti explorer and also able to use the roles & users defined in the ldap to assign tasks in activiti.

I am getting following error when I click the links Users & Groups under Manage tab within Activiti Explorer.

Do I need to customize something here.
