Lab Objectives

In this lab, you will learn how to perform the following tasks:

  • Enable a Microsoft Office InfoPath 2007 form to be signed in a Web browser

  • Sign an InfoPath form in Microsoft Internet Explorer

Lab Setup and Requirements

To complete this lab, you must have the following items on the client computer:

  • A digital certificate with which to sign the form. You can obtain a 60-day trial Class 1 Digital ID from VeriSign. In this case, VeriSign is the certification authority.

  • Access to a Microsoft Office SharePoint Server site on a server that is running InfoPath Forms Services.

For the user’s certificate to be trusted, the certificate of the certification authority must be installed in the Trusted Root certificate folder on the server. When you use a VeriSign certificate, it is installed with Windows Server 2003. If you are using a different certification authority, install the certificate in the Trusted Root folder on the server.


You can use different Web browsers to open InfoPath forms from a server running InfoPath Forms Services; however, you can only use Internet Explorer to digitally sign InfoPath forms.


The IT Department at Contoso Corporation has been asked to add support for digital signatures to the employee performance review form. Because many of the Contoso employees travel and work remotely, the forms must be available to be completed and signed in a Web browser.
