About User Groups and Package Replication
Although Integration Server is distributed with a predefined Replicator account, you can use a different account for package replication. As long as the subscription requester specifies an account that is a member of a group that is assigned to the Replicators ACL, that user can perform replication.
When publishing a package to another server, the publishing server uses the account specified by the subscription requester. For example, if the subscription requester (either the publisher or the subscriber) specified account DEPT01, the publisher will log into the subscriber server as DEPT01. DEPT01 must be a member of a group that is assigned to the Replicators ACL on the subscriber server.
