Two-Factor Authentication For Google Apps For Your Domain Using SSO/SAML And WiKID Strong Authentication Server
Everybody loves GMail. With Google Apps for you Domain, you can use GMail with your own domain, allowing organizations to outsource their email - and the requisite anti-spam filtering to Google. Webmail is very convenient, but for frequent travelers and those who use public wifi, it can be quite dangerous. Logging in from a kiosk or shared computer is a sure way to get your username and password stolen by a keystroke logger. While cloud services are great, maintaining security is tough.
In this document, we will add two-factor authentication to Google Apps for Your Domain using their SSO/SAML protocol and the open-source version of the WiKID Strong Authentication server.
Configuring the WiKID Strong Authentication Server
On the WiKID server, through the WiKIDAdmin web interface, enable the GoogleSSO protocol under Configuration, Enable Protocols:
Click on GoogleSSO
Click on Initialize.
Don't restart the server just yet.
WiKID two-factor authentication users are grouped into Domains. If you haven't done so, please create a WiKID Domain. The domain identifier is the zero-padded ip address of the server. So, 126.96.36.199 becomes 072044047107. Here we are using an internal LAN address which is fine for testing, but external clients will not be able to route to it.
Click on Create a New Domain
The required domain configuration options are:
Domain Name – This is a descriptive label for this domain visible only in the administration system.
Device Domain Name – This is the domain label that will appear in the menu option on the client device. This label should be relatively short to facilitate viewing on a mobile device.
Registered URL - This URL is for mutual https authentication and is not applicable here.
Server Code – This is the zero-padded IP address of the server or the pre-registered prefix in the wikidsystems.net domain. This value must be exactly 12 digits in length.
Minimum PIN Length - This is the minimum allowable PIN length for this domain. Any attempt to set a pin shorter than this value will generate an error on the client device.
Passcode Lifetime – This parameter specifies the maximum lifetime of the one-time passcode generated in this domain. After N elapsed seconds, the one-time passcode will automatically be invalidated.
Max Bad PIN Attempts – The maximum number of bad PINs attempted by a device in this domain before the device is disabled.
Max Bad Passcode Attempts – The maximum number of bad passcodes entered for a userid registered in this domain before the userid is disabled.
Max Sequential Offlines – The maximum number of times a device may use the offline challenge/response authentication before being required to authenticate online. This feature is used in the Enterprise version for the wireless clients when they are out-of-network coverage.
Require Locked Tokens - "Locked" software tokens are PC tokens that are tied to a particular PC by certain data from that PC such as the CPU identifier or the MAC address.
Require Wireless Tokens - If you prefer to use only wireless software tokens, check this box.
Use TACACS+ This for a TACACS+ only domain. Leave it unchecked.
Once, complete, click Create Domain.
For an external service, such as Google Apps for your Domain in this case, to talk to the WiKID server it needs to be configured as a Network Client on the WiKID Strong Authentication Server. Click on the Network Clients Tab of the WiKIDAdmin.
