Nortel Networks 4050 User Manual

492 Chapter 10 Configuring system settings

You can configure the Nortel SNAS 4050 cluster to use an external RADIUS 
server to authenticate system users. Authentication applies to both CLI and SREM 
users.

The user name and password defined on the RADIUS server must be the same as 
the user name and password defined on the Nortel SNAS 4050. When the user 
logs on, the RADIUS server authenticates the password. The user group (admin, 
oper, or certadmin) is picked up from the local definition of the user.

For more information about specifying user names, passwords, and group 
assignments for Nortel SNAS 4050 system users, see 

.

When you add an external RADIUS authentication server to the configuration, the 
server is automatically assigned an index number. You can add several RADIUS 
authentication servers, for backup purposes. Nortel SNAS 4050 authentication 
will be performed by an available server with the lowest index number. You can 
control authentication server usage by reassigning index numbers (see 

).

To configure the Nortel SNAS 4050 to support RADIUS authentication of system 
users, use the following command:
