The DirectoryEntry and DirectorySearcher, which use the Active Directory Services Interfaces (ADSI) technology. ADSI is the set of interfaces that Microsoft provides as a flexible tool for working with a variety of network providers. ADSI gives the administrator the ability to locate and manage resources on a network with relative ease, regardless of the size of the network.namespace provides easy access to Active Directory Domain Services from managed code. The namespace contains two component classes,
The ActiveDirectoryAccessRule class is used to represent an access control entry (ACE) in the discretionary access control list (DACL) of an Active Directory Domain Services object.
The ActiveDirectoryAuditRule is used to set an access control entry (ACE) on a system access control list (SACL). The ActiveDirectoryAccessRule contains the trustee, which is represented as an IdentityReference object. It also contains information about the access control type, access mask, and other properties such as inheritance flags. This rule is set on an ActiveDirectorySecurity object. After the ActiveDirectorySecurity is committed to the directory store, it will modify the security descriptor object according to the rules that are set on ActiveDirectoryAuditRule.
Uses the object security layer of the managed ACL library to wrap access control functionality for directory objects.
The CreateChildAccessRule class represents a specific type of access rule that is used to allow or deny an Active Directory Domain Services object the right to create child objects.
The DeleteChildAccessRule class represents a specific type of access rule that is used to allow or deny an Active Directory Domain Services object the right to delete child objects.
The DeleteTreeAccessRule class represents a specific type of access rule that is used to allow or deny an Active Directory Domain Services object the right to delete all child objects, regardless of the permissions that the child objects have.
Contains a collection of DirectoryEntry objects.
The DirectoryEntry class encapsulates a node or object in the Active Directory Domain Services hierarchy.
The DirectoryEntryConfiguration class provides a direct way to specify and obtain provider-specific options for manipulating a directory object. Typically, the options apply to search operations of the underlying directory store. The supported options are provider-specific.
Performs queries against Active Directory Domain Services.
Contains extended error information about an error that occurred when the Invoke method is called.
The DirectoryServicesPermission class allows you to control code access security permissions for .
Allows declarativepermission checks.
The DirectoryServicesPermissionEntry class defines the smallest unit of a code access security permission set for .
Contains a strongly-typed collection of DirectoryServicesPermissionEntry objects.
Specifies how to synchronize a directory within a domain.
The DirectoryVirtualListView class specifies how to conduct a virtual list view search. A virtual list view search enables users to view search results as address-book style virtual list views. It is specifically designed for very large result sets. Search data is retrieved in contiguous subsets of a sorted directory search.
Specifies how to construct directory virtual list view response.
Supports the .NET Framework infrastructure and is not intended to be used directly from code.
Represents a specific type of access rule that is used to allow or deny an Active Directory object an extended right. Extended rights are special operations that are not covered by the standard set of access rights. An example of an extended right is Send-As, which gives a user the right to send e-mail for another user. For a list of possible extended rights, see the topic Extended Rights in the MSDN Library at http://msdn.microsoft.com/library. For more information about extended rights, see the topic Control Access Rights, also in the MSDN Library.
The ListChildrenAccessRule class represents a specific type of access rule that is used to allow or deny an Active Directory Domain Services object the right to list child objects.
The PropertyAccessRule class represents a specific type of access rule that is used to allow or deny access to an Active Directory Domain Services property.
The PropertySetAccessRule class represents a specific type of access rule that is used to allow or deny access to an Active Directory Domain Services property set. For a list of property sets that are defined for Active Directory Domain Services, see the topic Property Sets in the MSDN Library at http://msdn.microsoft.com/library.
Contains the values of a DirectoryEntry property.
Contains the properties of a SearchResult instance.
Contains the values of a SearchResult property.
Specifies how to sort the results of a search.
The ActiveDirectoryRights enumeration specifies the access rights that are assigned to an Active Directory Domain Services object.
The ActiveDirectorySecurityInheritance enumeration specifies if, and how, ACE information is applied to an object and its descendents.
Contains flags that determine how directories within a domain will be synchronized. These options can be set for the DirectorySynchronization.Option property.
Specifies whether SSL is used when you set or change a password. This enumeration is used with the DirectoryEntryConfiguration.PasswordEncoding property.
The ReferralChasingOption enumeration specifies if and how referral chasing is pursued.
Specifies the possible scopes for a directory search that is performed using the DirectorySearcher object.
The SortDirection enumeration specifies how to sort the results of an Active Directory Domain Services query.
The classes in this namespace can be used with any of the Active Directory Domain Services service providers. The current providers are: Internet Information Services (IIS), Lightweight Directory Access Protocol (LDAP), Novell NetWare Directory Service (NDS), and WinNT.
ADSI is a programmatic interface for Microsoft Active Directory Domain Services that enables your applications to interact with diverse directories on a network using a single interface. Using ADSI, you can create applications that perform common tasks, such as backing up databases, accessing printers, and administering user accounts.
It is assumed that you have a general understanding of Active Directory Domain Services before using these classes. For more information on Active Directory Domain Services, see the topics Introduction to Active Directory Objects and Active Directory Technology Backgrounder, as well as the following topics in the MSDN library at http://msdn.microsoft.com/library:
Active Directory Domain Services use a tree structure. Each node in the tree contains a set of properties. Use this namespace to traverse, search, and modify the tree, and read and write to the properties of a node.
The DirectoryEntry class encapsulates a node or object in the Active Directory Domain Services hierarchy. Use this class for binding to objects, reading properties, and updating attributes. Together with helper classes, DirectoryEntry provides support for life-cycle management and navigation methods, including creating, deleting, renaming, moving a child node, and enumerating children.
Use the DirectorySearcher class to perform queries against the Active Directory Domain Services hierarchy. LDAP is the only system-supplied Active Directory Service Interfaces (ADSI) provider that supports searching.
Note: Many of the classes, methods, and properties in the LinkDemand code access security option. This means that the code access security demand only occurs during just-in-time compilation and that the demand is performed only on the calling assembly and not up the entire call stack. Because of this, callers should not pass objects that are created from this namespace at runtime to code that is not trusted.namespace use the
