Environment

Identity Manager 14.5 Standalone

Cause

This is due to CA directory problem.   impd-main failed to start.   impd-trusted.pem in ssld has changed to a newer version after the upgrade, and the dxmanaged service was expecting old certs.

Resolution

Replace new cert with old cert and restart DXserver.
