RSA SecurID external authentication service
When an RSA SecurID external authentication service is added, the DSView 3 software obtains
user authentication information and relays it to the RSA Authentication Manager. The RSA
Authentication Manager’s validation results are then relayed to the user. The DSView 3 software
also supports new PIN operations, next tokencode operations, RSA Authentication Manager
Replica functionality and name locking. The DSView 3 software is the agent type Net OS Agent.
See RSA SecurID login on page 17 for information about the login process when an RSA SecurID
external authentication service is used. Consult the RSA Authentication Manager documentation
for additional details.
