234Chapter 6 Configuring authentication

Overview

The Nortel SNAS 4050 controls authentication of clients when they log on to the network.

The Nortel SNA solution supports the following authentication methods in Nortel Secure Network Access Switch Software Release 1.0:

•external database

—Remote Authentication Dial-In User Service (RADIUS)

—Lightweight Directory Access Protocol (LDAP)

•local database on the Nortel SNAS 4050

Note: If you ran the quick setup wizard during initial setup, the Local database authentication method has been created as Authentication 1.

You can configure more than one authentication method within a Nortel

SNAS 4050 domain. You determine the order in which the methods are applied by default. Client credentials are checked against the various authentication databases until the first match is found.

You can configure the methods so that their names display on the portal login page (see “Configuring authentication methods using the CLI” on page 239 or “Configuring authentication methods using the SREM” on page 270). You can then direct clients to select a specific authentication server (for example, for direction to a specific Windows domain). If the client selects a Login Service name, the authentication request is directed immediately to the specified service. Otherwise, authentication defaults to being carried out according to the authentication order you have configured (see “Specifying authentication fallback order using the CLI” on page 267 or “Specifying authentication fallback order using the SREM” on page 314).
