The Turnitin Blackboard Direct V2.5 integration is not currently compatible with the LRNSI-18971 Blackboard security patch. If your Blackboard environment has this patch installed a "java.net.SocketException:Unconnected sockets not implemented" message may be encountered when attempting to access Turnitin assignment points.
If you encounter this error, you can contact BlackBoard directly who have now released a new LDAP plugin which will fix the error. The Blackboard support team can help you get and install this new plugin. Once this LDAP plugin is successfully installed the plugin error will be resolved.
Please accept our apologies for any inconvenience that this issue may have caused.
