314 Chapter 6 Configuring authentication
320818-A
Specifying authentication fallback order using the SREM
Authentication in the Nortel SNAS 4050 solution is performed by checking client
credentials against available authentication databases until the first match is
found. You specify the order in which the Nortel SNAS 4050 applies the methods
configured for the Nortel SNAS 4050 domain.
Perform this step even if there is only one method defined on the Nortel
SNAS 4050.
Note: For best performance, set the authentication order so that the
method that supports the biggest proportion of users is applied first.
However, if you use the Nortel SNAS 4050 local database as one of the
authentication methods, Nortel recommends that you set the Local
method to be first in the authentication order. The Local method is
performed extremely fast, regardless of the number of users in the
database. Response times for the other methods depend on such factors
as current network load, server performance, and number of users in the
database.
