D-Link NetDefendOS User Manual page 651

Some points to note about setting up multi factor authentication with NetDefendOS are the
following:
• The same NetDefendOS setup is used if the challenge code is generated by a local code
generating device such as the RSA SecureID™ product or if a RADIUS server causes it to be
sent to the user.
• No extra configuration is required in NetDefendOS. However, if the banner file
LoginChallenge is used in the challenge process, it may need to be edited to display the
appropriate text. This is discussed further in Section 8.4, "Customizing Authentication HTML".
• The administrator must configure the RADIUS server appropriately and the server's
documentation should be consulted on how to do this.
• If the RADIUS server causes a code to be sent to the user, this is independent of
NetDefendOS. Various third party solutions are available to generate this code.
