4.4.5 RADIUS Authentication
RADIUS authentication provides a means to use an external RADIUS server for
authentication purposes when logging in to VersaSync. RADIUS allows the login
password for user-created accounts to be stored and maintained in a central
RADIUS server on the network.
This function greatly simplifies password management: Instead of having to
change a password in many network appliances, it is changed on the RADIUS
server only.
In order to use RADIUS authentication with VersaSync, RADIUS and the RADIUS
network server first need to be configured. Currently, http/https/ssh/telnet/ftp
protocols are supported, i.e. you can login to a VersaSync unit using RADIUS
authentication via applications using any of these protocols.
Caution: In order to utilize RADIUS authentication, the account user-
name on the RADIUS server must NOT be used with a local user
account.
E x a m p l e :
A user with the username user3 on the RADIUS server will not be able to login to a Ver-
saSync unit, if on that unit a local user account with the username user3 exists.
However, once the user deleted the local user3 account, she will be able to login with
the RADIUS user3 account.
