Free SMS Token solution for Web Interface

Saturday, 30 June 2007 by Michel Roth

Thomas Koetzing mentions a really cool addition to the Citrix Web Interface. This addition makes it possible to do two factor authentication with the Citrix Web Interface (4.0 and 4.5).

The solution consists of two parts. First part adds a new Tab to the User properties in Active Directory (it's not a schema extension). Setting the mobile phone number and a token PIN is all that has to be done in the User properties. Second part is the modification of Web Interface to add the SMS Token authentication and is quite easy. After setting the SMS properties for the used SMS Gateway (designed to use an online SMS Gateway - sending HTML request) your done to use SMS Tokens.

Really cool stuff and it's free too! You do have to pay for sending the SMS messages of course but that is still a modest price to pay for this kind of two factor authentication. You can download the software from the beautiful website of it's creator, Claus Isager.
