Applies to Barracuda SSL VPN.



Aladdin eToken PRO makes use of SSL Client certificate authentication to present a digital

certificate to the Barracuda SSL VPN server. The only real difference from the perspective of

the administrator is that the eToken software itself that requires installing manually on the

client PCs.

The following are the steps to set up the Barracuda SSL VPN to use a standard Aladdin

eToken PRO device that uses SSL client certificate authentication:

  1. Configure SSL client certificate authentication.
  2. Create SSL client certificates. Use one of the following methods:
    • Generate SSL client for your users using the built-in CA.
    • Import existing SSL client certificates purchased from an existing CA.
  3. Configure an authentication scheme that uses SSL client certificates.
  4. Import these certificates into each device using the eToken Properties tool.
  5. Issue devices to your users.

Aladdin eTokens can be managed quite easily using a software tool named eToken

Properties. This tool can detect Aladdin devices that can be connected using the USB port

and is used to initialize, set passwords and import certificates onto the devices.


The first thing you should do is to set a password on your devices. The standard password

that is set on factory-initialized devices is 0123456789. Click Change Password to set the

password to something more secure.

A password complexity meter is provided to give you an indicator of how secure your

password is. Use a combination of upper and lower case letters, numerals and punctuation

marks to create stronger passwords.


Next, import the SSL client certificate onto the device. On the Certificates & Keys tab, select

Import Certificate and then choose Import Certificate from File.


Select the P12 file and open it. You will then be prompted for the passphrase.


When the passphrase is entered successfully, the certificate is imported onto the device.
