RADIUS

RADIUS (Remote Authentication Dial-In User Service) is a client/server security protocol most widely known for enabling remote authentication and access. You can enable your network to use any authentication method that supports the RADIUS standard.-including token cards and smartcards-simply by installing and configuring the RADIUS adapter. The RADIUS authentication adapter requires you to set the following parameters:

Host Name
The host name of your primary RADIUS server.
Default = localhost
Port Number
The listening port number of your primary RADIUS server.
Default = 1645
Timeout (seconds)
The number of seconds the Oracle server will wait for a response from the primary RADIUS server.
Default = 15 seconds
Number of Retries
The number of times the Oracle server should send messages to the primary RADIUS server.
Default = 3
Secret File
The file location of the secret key on the Oracle server. For security reasons, Oracle recommends that you change this file to root access only.
Send Accounting
RADIUS Accounting logs Oracle server access information and stores this information in a file on the RADIIUS accounting server. You can use this feature only when both your RADIUS authentication servers support this feature.
Values = ON or OFF.
Challenge Response
The value of this field is ON when you want to present the user with a challenge-response GUI.

Default = challenge.
Interface Class Name
