Assigning and Managing Permissions for Elements
You can limit access to elements to groups of users by using access control lists (ACLs). Typically created by a system administrator, ACLs allow you to restrict access on a broader level. For example, if you have a production package and a development package on the Integration Server, you can restrict access to the production package to users in an Administrators ACL, and restrict access to the development package to users in a Developers ACL.
Within ACLs, you can also assign different levels of access, depending on the access that you want different groups of users to have. For example, you may want a “Tester” ACL to only have Read and Execute access to elements. Or, you may want a “Contractor” ACL that denies List access to sensitive packages on the Integration Server, so that contractors never see them in Designer.
