NDS - NetWare Directory Services
This is the most important feature of NetWare 4.x.  Directory Services
allows each user to have a single login to the entire network, regardless of
it's size and the number of servers.

ROOT - NDS is often explained as an upside down tree, the leaves of the tree
being the user accounts.
The root is the topmost level of the directory tree.

Leaf Object - In the tree,  objects called containers (like Organization,
Country, or Organizational Unit) can hold other objects.  Leaf objects are
not containers, they are the actual managed objects.  They include user
accounts, print queues, fileservers, etc.

Context - When a user logs into the network, they will have a pointer to
some location in the tree, whether it's the ROOT (top level), or more
likely, some container level.  This is their current context, and when they
browse for servers, printers, volumes, etc, the leaf objects that are in the
context they are
pointed to will be seen.  If they want to access another container, they
change context to that location.

Replication - NDS is a loosely consistent database, spread across one or
more servers, depending on the skill of the network staff and the size of
the network.  As the NDS tree gets larger,  it's often better to split off
portions of the tree into partitions.  These partitions can be placed on
specific servers in the tree, so these servers don't have to maintain a copy
of the entire tree.  A replica is a copy of a partition ( or a copy of the
ROOT partition, since it is automatically a partition) on a specific server.
This replica can be the master replica (all other replicas of the partition
get their updates from it), a read-write replica, or a read-only replica.
In a global WAN, it would be foolish for a site on the other side of the
world to have a copy of the users in your local office.  Partitions allow
you to define what portions of the tree are kept at specific locations, and
replicas allow you to keep more than just one (the master) copy of a
replica.  Thus, if a server fails, that portion of the tree can still be
read from any other server on the net with a replica of the specific
partition.

Bottom line - NDS allows for global networks with central administration.
Much better solution than Microsoft's domain structure for managing the
network.
