Problem in using Code Signing Certificate

[ss]

Hi,

I have an issue in using the certificate created by Enterprise CA.

I have some infopath forms that contains managed code behind them. In order
to publish them to sharepoint server with 'Full Trust' as security level, we
have created a Code Signing Certificate using Certification Server of Windows
server 2003.

I have copied that Certificate on to the machine on which InfoPath forms
exists and I have installed this certificate in the 'Personal ' folder using
mmc.

Now, I am trying to sign the form with this certificate by going into Form
Tools-->Form Options-->Security and Trust-->Selected Full Trust Radio button

When I am selecting the checkbox 'Sign this form template' and clicking the
'Select Certificate' button, it is not showing me the code signing
certificate. How can I use this certificate to sign my infopath forms?

(I have also added the certificate into Trusted publishers folder using mmc).

Environment:InfoPath 2007, Moss 2007

'Personal' folder of which store? The "Current User" store or the "Local
Computer" store? And did the certificates you installed contain a private
key? More information can be found in this article

I tried testing it by adding at both places, 'Personal' folder of "Current
User" and also "Local Computer". No, this Certifcate doesn't contains a
Private key.

TIA

If you did not install a certificate that contained a private key, you will
not be able to use it for signing. See the characteristics listed under
"Valid Digital Certificates for Signing Data in InfoPath Forms" in the
article I previously mentioned.
