Lock pdf with multiple digital signatures when certify is grayed out.

The document will contain multiple signatures. Once one individual signs, the certify digital signature grays out. We have tried certifying first. Then, no signatures can be added even though it was specified in security to allow additional signatures. Also, signatures can be deleted by other individuals besides the signee which is why the document needs to be locked or protected.

Each digital signature that is applied is changing the PDF. If you need multiple signatures, use Signature fields and not lock the other signature fields. The digital signature also validates if the PDF has been modified in any way since the PDF was signed.

Also if any of the users will be using Adobe Reader, then you need to apply Extended Reader Rights to the form.
