Who Can Subscribe?
Any Integration Server can subscribe to a package on another server if both servers allow it from a security perspective. Security for package replication is accomplished a number of ways:
*Userid and password. In order to send a package to a subscriber, the publisher must login to the subscriber by specifying a userid and password that exist on the subscriber.
*ACLs. The userid the publisher uses to log on to the subscriber must be a member of a group that is assigned to the Replicators ACL or higher on the subscriber.
*SSL.You can specify that the servers involved in package replication connect to each other using SSL.
The publisher maintains a list of subscribing servers for each package.
Subscriptions can be added by the publisher or the subscriber:
*Publisher. The administrator of a publishing server can use the publisher functions to add (or remove) subscribers to any package that originates on the publishing server (i.e., one to which you do not subscribe).
*Subscriber. The administrator of a remote Integration Server (the subscriber) can submit a subscription request to the publisher. When the publisher receives this request, it automatically adds that server to the subscription list for the requested package as long as authentication was successful. Subscribers can also issue cancellation requests (i.e., cancel their subscriptions) for packages to which they subscribe.
