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.
