Short Description

The Delegated Administration Service PowerShell snap-in provides administrative functions for the Delegated Administration Service.

Command Prefix

All commands in this snap-in have the noun prefixed with 'Admin'.

Long Description

The Delegated Administration Service PowerShell snap-in enables both local and remote administration of the Delegated Administration Service.

The Delegated Administration Service (or DAS for short) stores information about Citrix administrators and the rights they have. Services in the XenDesktop deployment use the DAS to determine whether a particular user has the privilege to perform an operation or not.

The snap-in provides storage and configuration of these entities:

Administrators Each administrator object represents an individual person or a group of people identified by their Active Directory account. Administrators can be enabled and disabled.

The effective rights that a user has is the union of any rights that they have by looking at their Active Directory group membership. Disabled administrator entries are ignored for this calculation.

Once a site is setup, there must always be a full administrator and the Delegated Administration snap-in rejects requests to remove or disable the last full administrator.

Roles A role represents a job function. That is, anyone with a given role is expected to be able to use or perform the tasks, wizards, and actions associated with that role. Administrators may have multiple roles for a particular site.

Some roles are built-in, and some editions of the product allow custom roles to be created with different combinations of permissions.

Scopes Scopes represent a collection of objects, and are used to group objects for administrative purposes in a way that is relevant to the organisation. They can be used to represent both hierarchical and non-hierarchical relationships.

Objects can exist in multiple scopes at once. You may find it easier to think of scopes as labels, or a non-exclusive grouping such as a play-list.

All objects are implicitly in the built-in 'All' scope.

Some objects are not scoped, and access to them is through either the 'All' scope or indirectly through a scoped object. For example sessions are not directly scoped but can be accessed using the scope of the desktop group.

The DAS stores information about scopes, but the mapping between scopes and objects is stored and updated using the PowerShell snap-ins of each corresponding service. For example, Delivery Group scopes are managed using the Broker PowerShell snap-in.

Rights Rights determine what an administrator can do and where they can do it. They are expressed as a number of <role, scope> pairs associated with each administrator.

To gain access to any particular object, a person must match an administrator object that has an appropriate right that allows the required operation in a scope that the object is a member of.

Permissions Each task, wizard or action in the Citrix Studio or Director consoles represents a unit of functionality that an administrator can perform. Permissions are expressed at a high level and generally correspond directly to the labels in the consoles. For example: "Edit catalog", or "Create delivery group".

Permission groups: Permissions are grouped into related functionality when displayed by the console.

Operations Operations are the indivisible unit of functionality that each XenDesktop service can perform, and usually correspond to individual cmdlets. Internally, each permission requires a number of operations to be performed, possibly by different services.
