Our ZCM has suddenly stopped communicating with its User Source for no apparent reason. Our authenticating Username is valid and functional within eDir, but its communication with the LDAP directory has supposedly failed according to ZCC. LDAP seems to be functional however, although I can't guarantee that yet. I'm wondering if it can be another underlying issue instead of the purported LDAP failure.

Reason being, the only changes prior to its ceasing to function are a reboot of this ZCM server and subsequent move of it Virtual Machine within VMware vCenter to its newly-upgraded ESXi host. Hasn't worked since. Could this possibly play in? I'd welcome any insight and advice.
