2. To enable a method currently in the Disabled methods list, select the method and
press the left arrow to the left of the list. The methods include:
NIS (Network
Information
System)
A network naming and administration system developed by Sun
Microsystems for smaller networks. Each host client or server
computer in the system has knowledge about the entire system. A user
at any host can access files or applications on any host in the network
with a single user identification and password.
NIS uses the client/server model and the Remote Procedure Call
(RPC) interface for communication between hosts. NIS consists of a
server, a library of client programs, and some administrative tools. NIS
is often used with the Network File System (NFS).
LDAP (Lightweight
Directory Access
Protocol)
A set of protocols for accessing information directories, specifically
X.500-based directory services. LDAP runs over TCP/IP or other
connection-oriented transfer services.
RADIUS (Remote
Authentication
Dial-In User
Service)
An authentication and accounting system used by many Internet
Service Providers (ISPs). A client/server protocol, it enables remote
access servers to authenticate dial-in users and authorize their access
to the requested system or service.
RADIUS allows a company to maintain user profiles in a central
database that all remote servers can share. It increases security,
allowing a company to set up a policy that can be applied at a single
administered network point.
Kerberos
Kerberos is a network authentication protocol that enables two parties
to exchange private information across an unprotected network.
It works by assigning a unique electronic credential, called a ticket, to
each user who logs on to the network. The ticket is embedded in
messages to identify the sender.
