> When running syncrepl client (ReplicationConsumerImpl) with startTLS enabled the first connection attempt fails with the the exception below. This occurs because there is no TCP connection established when the LDAP Start TLS extended request is attempted.

> Subsequent connection attempts fail if confidentiality is enabled as the ReplicationConsumerImpl connect() code bypasses the startTLS if the LdapNetworkConnection has already been created. This results in the following exception.

> A fix to both exceptions is to ensure that the LDAPNetworkConnection startTls() call is preceeded with a call to LDAPNetworkConnection connect() and and also ensure that if startTLS is enabled, the calls to connect() and startTls() are made for each ReplicationConsumerImpl connection attempt.
> I will attach an svn diff of the fix that works within my development environment.
