I have install exchange 2010 hub/cas/mailbox in two servers and edge role in one server. I did the synchronization file from edge, imported in HUB server. When I make "Test- Edgesynchronization" I got the following error:
FailureDetails : The LDAP server is unavailable
DNS working fine between all servers, windows firewall is off in all servers.
I don't know, I read something related to the certificate in exchange edge!?
