NDS (Novell Directory Services) is a feature in NetWare 4.x that implements a distributed directory service similar to the X.500 specification. Novell has adapted NDS for use on Windows NT and UNIX platforms. A special e-commerce version of NDS is also available. Active Directory combines features of the internet's DNS locator service and X.500 naming. LDAP is the core access protocol for the service. LDAP will allow Microsoft's Active Directory to work across operating system boundaries and integrate multiple name spaces, thus allowing administrators to manage other vendors' directory services. Differences 1)
Active Directory Based on TCPIP
DNS Server Resource Records ( MX-Record)
LDAP for internal searches, each object has a unique GUID example on following page
All Domain Controllers are native LDAP Servers
Integrates with DNS NDS
Originally based on IPX/SPX
Service Advertising Protocol (SAP) to advertise Services
Implemented in TCPIP with
Service Location Protocol (SLIP) also advertisement based
SLIP does not integrate with DNS proprietary
When implemented together reduces network performance because routers must support RIP that allows for both SLIP and SAP protocols
Not a native LDAP Server - it has a LDAP interface that translates LDAP request to native NDAP protocols
2)Internet Standards Support Active Directory
Native LDAP server
Full namespace integration with DNS
Integrated support for PKI technologies
NDS
LDAP requests are translated
No Namespace Integration with DNS
Limited Integration with PKI

The Active Directory administrative tools can only be used from a computer with access to a domain. The following Active Directory administrative tools are available on the Administrative Tools menu: Active Directory Users and Computers (dsa.msc) Active Directory Domains and Trusts (domain.msc) Active Directory Sites and Services (dssite.msc)
Active Directory service is used to store information about the network resources across a domain and also centralize the network.

Active Directory Federation Services was developed by Microsoft. It is a software component that can be installed on Windows. It is designed to maintain application security and implement federal identity.
Active Directory Services is included with most Windows systems as it is a product of Microsoft. It is often used with Windows domain networks, authorizing computers within the network.
Active Directory Recycle Bin is a feature that helps minimize directory service downtime by enhancing your ability to preserve and restore accidentally deleted Active Directory objects without restoring Active Directory data from backups, restarting Active Directory Domain Services (AD DS), or rebooting domain controllers. When you enable Active Directory Recycle Bin feature, all link-valued and non-link-valued attributes of the deleted Active Directory objects are preserved and the objects are restored in their entirety to the same consistent logical state that they were in immediately before deletion. For example, restored user accounts automatically regain all group memberships and corresponding access rights that they had immediately before deletion, within and across domains. Active Directory Recycle Bin is functional for both AD DS and Active Directory Lightweight Directory Services (AD LDS) environments. Mohannad Hamid
