Active Directory Services Features
Active Directory in the Windows Server 2003 family is a significant enhancement over the flat domain model provided in Windows NT
. Active Directory is integrated within the Windows Server 2003 family and offers the following features:
Replication of information Active Directory provides multimaster replication MCSE Certification(http://www.mcse-70-294.com) technology to ensure information availability, fault tolerance, load balancing, and other performance benefits. Multimaster replication enables you to update the directory at any domain controller and replicates directory changes to any other domain controller. Because multiple domain controllers are employed, replication continues, even if any single domain controller stops working.
Flexible, secure authentication and authorization Active Directory authentication and authorization services provide protection for data while minimizing barriers to doing business over the Internet. Active Directory supports multiple authentication protocols, such as the Kerberos version 5 protocol, Secure Sockets
Layer (SSL) version 3, and Transport Layer Security (TLS) using X.509 version 3 certificates. In addition, Active Directory provides security groups that span domains.
Security integration Active Directory is integrated with Windows Server 2003 security MCSE Exam(http://www.mcse-70-294.com) access control can be defined for each object in the directory and on each property of each object. Security policies can be applied locally, or to a specified site, domain, or organizational unit.
Directory-enabled applications and infrastructure Features within Active
Directory make it easier for you to configure and manage applications and other directory-enabled network components. In addition, Active Directory provides a powerful development environment through Active Directory Service Interfaces
(ADSI).
Interoperability with other directory services Active Directory is based on standard directory access protocols, including Lightweight Directory Access Protocol (WAP) version 3, and the Name Service Provider Interface (NSPI), and can interoperate with other directory services employing these protocols. Because the
LDAP directory access protocol is an industry-standard directory IT Exams(http://www.buyitexam.com) service protocol,programs can be developed using LDAP to share Active Directory information with other directory services that also support LDAP. The NSPI protocol, which is used by Microsoft Exchange Server 4 and 5.x clients, is supported by Active Directory to provide compatibility with the Exchange directory.
Signed and encrypted LDAP traffic By default, Active Directory tools in Windows Server 2003 sign and encrypt all LDAP traffic by default. Signing LDAP traffic guarantees that the packaged data comes from a known source and that it has not been tampered with.
