We are using certificates created by Active Directory Certificate Services, and stored within AD. We can sign documents with the certificates, but would like the added layer of security to have Acrobat prompt the user to enter their AD password again to apply the signature. The reasoning...if a user walks away from their computer and does not lock it, anyone can come up and create and sign a document with the other person's signature. If we can prompt the user for authentication again when they click Sign, this problem would be avoided.
Thanks
