Novells Directory Service and Microsofts Active Directory both are based on X.500 or a subset of it. Novell has been the leader for years, and Microsoft seeks to unseat
the leader. X.500 The X.500 standard was ratified in 1988, and updated in 1993 and 1997. Seemingly ancient by todays pace of
change, X.500 still is the leading directory protocol. X.500 originally was intended to provide a directory mechanism for the existing X.400. X.500 since has expanded "to include many
other objects, and some even see it as the best method to uniquely identify every object in all networks" (Chacon, 1999; p. 46).
"The core of the X.500 model is a distributed database, which contains useful information about an object" (Chacon, 1999; p. 46), including information about its attributes. With proper permission,
people and programs "can read or modify information in the database ... The X.500 term for the entire distributed database is the Directory Information Base (DIB), and its distributed components
are Directory System Agents (DSA)" (Chacon, 1999; p. 46). X.500 is complex and resource-intensive, features that likely have prevented it from becoming the
world leader in directory protocol. "A subset of X.500, called Lightweight Directory Access Protocol (LDAP), is helping to break through this impasse. Ultimately, X.500s greatest role may be that
it was responsible for the implementation and character of LDAP" (Chacon, 1999; p. 46). Novell Directory Services Chacon (1999) reports that, at the
time of writing, Novell Directory Services (NDS) was "probably the most widely used directory service in terms of number of seats, due to the proliferation of NetWare on the LAN"
