We have a customer who is looking for a greenfield AD installation for 700-800 users. It is a rather straightforward AD implementation - but they are requesting AD authentication for some externally hosted services also. The main service they are looking to integrate at the moment is Blackboard. We have verified that this supports AD integration.
From what I have seen, AD integration is usually only used for internal services - how would we (securely) allow these remote services to authenticate back to the local domain from the internet? I am not sure where to begin with this one.
Thanks in advance.
