We have SDP free version installed on a linux machine. we also have paid for versions of ADmanager and ADselfservice on another windows machine. I have been able to do the integration for ADselfservice, connection works both ways. but for ADmanager the connection from SDP to ADmanager gets a "ME integrations not updated" error. it connects the other way around ADmanager to SDP.
I have tried by IP address and hostname
ADmanager is https while the others don't.
