Hi Bob,
There is no way to enable Identity Awareness globally.
This should be enabled on the gateway object on CMA level.
As for the questions raised in this thread regarding sharing identities between MDS domains, although Identity Collector is not assigned to specific domain and therefore it can overcome this issue, we do not recommend configuring it as the sharing method.
There is a customer release of "Identity Broker" which is PDP to PDP sharing over MDS domains.
In case this is relevant for your environment, I suggest contacting your local SE and open RFE.
Thanks,
