certificate error in browser but not InfoPath

Question

We have created a form in Infopath 2010 for use with SharePoint 2010. The form contains digital signatures. If I open the form in InfoPath the DS loads with no problem. However, if I open the form from the browser, IE9, I get a "Revocation Status cannot be verified" error. How can I troubleshoot/fix/supress the error?

Thanks

Answer 1

Maybe you need to add the cert's root certs into central admin. You do this under security and manage trust.

Answer 2

Usually one gets such error when the Infopath itself is used for generating a certificate instead of getting it from a Certificate Authority but it was not exported from development machine where it was generated and imported into computer store on Sharepoint server as Trusted Root CA.

Note also that:

• List Templates, in contrast to Form Library Templates, do not support that digital signing - cf. Table 3 of Building SharePoint Applications with InfoPath 2010 (Part 1 of 2)
• If a form template was designed based on an XML Schema, you can enable digital signatures for that form template only if the XML Schema has a node that is in the World Wide Web Consortium (W3C) XML digital signature namespace. Read Digital Signatures in InfoPath 2010
• The Signature Line control is only available in InfoPath 2010 client (Filler) form but unsupported in Web browser form. Read Digital Signatures in InfoPath 2010
