Security Certificate Multiple DMPs http://developer.cisco.com/c/message_boards/find_recent_posts?p_l_id= 2013-05-20T14:46:32Z 2013-05-20T14:46:32Z Stephanie McQuown http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5377381 2012-03-29T20:02:46Z 2012-03-29T20:02:46Z

We are a control system software developer with a customer with about 30 DMPs. All DMPs were not communicating properly, so we thought we would need to update the security certificates. After updating one certificate, about 10 of the DMPs started working. Updating a second unique certificate fixed about another 5. We have read here in the forums that each DMP would need a unique certificate. Any idea why several DMPs would start working when a single certificate was updated? Also is there a way to install a root certificate that would update all the DMPs?
