Environment Admin
To use an IMS organization or Experience Platform sandbox in Demo System Next, a user must be granted access. This access is managed separately from the underlying provisioning and permissions in Adobe CX Enterprise. In practice, that means the user must be assigned both the relevant IMS organization and the relevant AEP sandbox in Demo System Next, even if access has already been configured elsewhere, such as in Quick Setup. There are two primary self-service tools:
- IMS Org Admin - allowing admins to add or update IMS Orgs and integration details
- Environment Admin - allowing users to assign users to orgs and sandboxes.
Environment Admin

This view allows you to assign others to orgs as both users and admins, and specify which sandboxes should be visible for them in DSN. This affects which environments (org/sandbox) they can select in Quick Setup or view in the Environment list.
Removing a user (or self) from an org in this view unassigns them from the org altogether, so be careful not to remove yourself from an administered org by accident.
