        return JiveGlobals.getBooleanProperty(ConnectionSettings.Server.TLS_ACCEPT_SELFSIGNED_CERTS, false);
    }
Returns true if server dialback can be used when the remote server presented a self-signed
certificate. During TLS the remote server can present a self-signed certificate, if this
setting is enabled then the self-signed certificate will be accepted and if SASL EXTERNAL
is not offered then server dialback will be used for verifying the remote server.<p>

If self-signed certificates are accepted then server dialback over TLS is enabled.

@return true if server dialback can be used when the remote server presented a self-signed
certificate.
