ACTIVE DIRECTORY (AD)
Active Directory serves as a single data store for quick data access to all users
iStreet offers Active Directory (AD) a Windows OS directory service that facilitates working with interconnected, complex and different network resources in a unified manner.
Active Directory provides a common interface for organizing and maintaining information related to resources connected to a variety of network directories. The directories may be systems-based (like Windows OS), application-specific or network resources. Active Directory serves as a single data store for quick data access to all users and controls access to users based on the directory's security policy. 
Active Directory provides the following network services:
- Lightweight Directory Access Protocol (LDAP) - An open standard used to access other directory services
- Security service using the principles of Secure Sockets Layer (SSL) and Kerberos-based authentication
- Hierarchical and internal storage of organizational data in a centralized location for faster access and better network administration
- Data availability in multiple servers with concurrent updates to provide better scalability
