Authentication Methods for User Login

The security appliance supports the following authentication methods for user
login.
• Local Database: Allows you to use the local database for authentication if
the number of users is relatively small. Only the local users in local database
are allowed to access the network resources. See
for Authentication, page
• RADIUS: Allows you to use the RADIUS server for authentication if you
have more than 100 users. See
page 279.
• RADIUS + Local Database: Allows you to use both the RADIUS server and
local database for authentication. See
Server for Authentication, page
• LDAP: Allows you to use the LDAP for authentication if you use an AAA
server such as LDAP and AD to maintain the user and user group
information. See
• LDAP + Local Database: Allows you to use both the LDAP and local
database for authentication. See
Authentication, page
