Mediator exposes several Web service operations to allow CentraSite to manage deployed assets. This Web service is invoked by CentraSite any time a user deploys or undeploys a virtual service or consumer application to Mediator. A Mediator's configuration details page includes the User Name and Password fields which identify an Integration Server user who is permitted to execute the Integration Server services associated with Mediator's deployer service. After installation, only members of the Integration Server “Administrators” group are allowed to invoke these services. However, administrators have the flexibility to allow their own users or groups to invoke them. Access to these services is controlled by an ACL, called MediatorDeployer. Initially, only the predefined “Administrators” group is assigned to this ACL. An Integration Server administrator can remove this group and add other groups or individual users. For example, you can create your own deployer group, (for example, “MyDeployers”) and add Integration Server user IDs to this group. Then, the user must update the MediatorDeployer ACL by removing the “Administrators” group and adding the “MyDeployers” group. Now, on the target's configuration detail page, you can specify any user ID that belongs to “MyDeployers” group.
