RADIUS user configuration
When configured to use RADIUS support, the IX10 device uses a remote RADIUS server for user
authentication (password verification) and authorization (assigning the access level of the user).
Additional RADIUS servers can be configured as backup servers for user authentication.
This section outlines how to configure a RADIUS server to be used for user authentication on your IX10
device.
Example FreeRADIUS configuration
With FreeRADIUS, users are defined in the users file in your FreeRADIUS installation. To define users:
1. Open the FreeRadius user file in a text editor. For example:
$ sudo gedit /etc/freeradius/3.0/users
2. Add users to the file using the following format:
user1 Cleartext-Password := "user1"
Unix-FTP-Group-Names := "admin"
user2 Cleartext-Password := "user2"
Unix-FTP-Group-Names := "serial"
The Unix-FTP-Group-Names attribute is optional. If used, the value must correspond to
authentication groups configured on your IX10. Alternatively, if the user is also configured as a
local user on the IX10 device and the RADIUS server authenticates the user but does not return
any groups, the local configuration determines the list of groups. See
more information about authentication groups. The Unix-FTP-Group-Names attribute can
contain one group or multiple groups in a comma-separated list.
3. Save and close the file.
4. Verify that your changes did not introduce any syntax errors:
$ sudo freeradius -CX
This should return a message that completes similar to:
...
Configuration appears to be OK
5. Restart the FreeRADIUS server:
$ sudo /etc/init.d/freeradius restart
RADIUS server failover and fallback to local configuration
In addition to the primary RADIUS server, you can also configure your IX10 device to use backup
RADIUS servers. Backup RADIUS servers are used for authentication requests when the primary
RADIUS server is unavailable.
Falling back to local authentication
With user authentication methods, you can configure your IX10 device to use multiple types of
authentication. For example, you can configure both RADIUS authentication and local authentication,
so that local authentication can be used as a fallback mechanism if the primary and backup RADIUS
