Changes

OVD LDAPS (LDAP SSL) listener is configured to use a certificate from a specific commercial certificate authority.
In order to collect related metrics, EM Agent  is searching to OVD LDAPS.
Trusted Root Certicates for CA (CA's) that OVD uses is missing from EM Agent monwallet.
Hence, EM Agent does not know about these certificates to complete the SSL handshake to access the OVD resource and it fails to collect metrics.

Please note that it is not required to use SSL in order to see the above graphs. This document explains the configuration changes when the SSL is used. If SSL is NOT used in the environment, then the above graphs are available without any additional change.
