Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services . [ 1 ] [ 2 ] Originally, only centralized domain management used Active Directory.
Ambiguous Name Resolution (ANR) is a feature available in Microsoft's Active Directory which allows resolution of multiple objects on a computer network based on limited input. The user will be able to select the correct entry from these results. To allow this feature to operate, attributes need to be ANR enabled in the directory schema.
Attribute values can be set-valued or atomic-valued. Set-valued attributes contain more than one atomic value. Examples are role and project. Atomic-valued attributes contain only one atomic value. Examples are clearance and sensitivity. Attributes can be compared to static values or to one another, thus enabling relation-based access control.
AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource ...
In computing, a directory service or name service maps the names of network resources to their respective network addresses.It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects.
An attribute has a name (an attribute type or attribute description) and one or more values. The attributes are defined in a schema (see below). Each entry has a unique identifier: its Distinguished Name (DN). This consists of its Relative Distinguished Name (RDN), constructed from some attribute(s) in the entry, followed by the parent entry's DN.
Active Directory extends the LDAP specification by adding the same type of access-control list mechanism as Windows NT uses for the NTFS filesystem. Windows 2000 then extended the syntax for access-control entries such that they could not only grant or deny access to entire LDAP objects, but also to individual attributes within these objects.

Attribute-based access control or ABAC is a model which evolves from RBAC to consider additional attributes in addition to roles and groups. In ABAC, it is possible to use attributes of: the user e.g. citizenship, clearance, the resource e.g. classification, department, owner, the action, and; the context e.g. time, location, IP.
