Digitally Sign option is disabled when document is certified (even if the DocMPD allows signatures)

Question

We are facing a issue when trying to implement certification signatures to avoid modifications after the first signature. Whenever we set the DocMDP transform with the value 2 (that should enable new signatures), adobe reader disables the option to digitalloy sign the document (Althoug in secutity properties signatures are supposedly allowed. Is it a bug on Adobe Reader? How can we sign certified documents in adobe reader?

Hi Tiago29933161s5dt,

Thank you for reaching out.

If I understand your issue correctly, one Digital Signature is added to the document, and you are trying to add a new digital signature on the same document. Please confirm if the first signer has changed the options provided under "Permitted Actions after Certifying" when adding the digital signature.

If not, would you mind sharing the complete workflow used to send the document for signature?

Please refer to the following document for information on creating and distributing PDF forms in Acrobat: https://helpx.adobe.com/acrobat/using/creating-distributing-pdf-forms.html.

Let us know if you have any questions.

Thanks,

Meenakshi
