User authentication
Remote Authentication Dial-In User Service (RADIUS)
Your AnywhereUSB Plus device supports Remote Authentication Dial-In User Service (RADIUS), a
networking protocol that provides centralized authentication and authorization management for
users who connect to the device. With RADIUS support, the AnywhereUSB Plus device acts as a
RADIUS client, which sends user credentials and connection parameters to a RADIUS server over
UDP. The RADIUS server then authenticates the RADIUS client requests and sends back a response
message to the device.
When you are using RADIUS authentication, you can have both local users and RADIUS users able to
log in to the device. To use RADIUS authentication, you must set up a RADIUS server that is
accessible by the AnywhereUSB Plus device prior to configuration. The process of setting up a
RADIUS server varies by the server environment. An example of a RADIUS server is FreeRADIUS.
