When I apply my certificate-based signature to a pdf and send it to another user for signature (via Adobe Sign for example), that user cannot apply their certificate-based signature on the document. They can only sign with the "Fill & Sign" tool.
Is there a way to enable having multiple users apply their certificate-based signature to a document after one another?
We are sorry for the trouble. As described, you want multiple certificate based signatures on the document.
Would you mind sharing the workflow/steps you are doing to send the document for signature? Are yoiu placing the signature fields for the other recipients or digital signature fields?
Also, what is the workflow/steps the user are doing to sign the PDF? Are they opening the form in web browser? if yes ask them to download the form to the computer and then open with Adobe Acrobat/Reader DC application and try to sign.
This is the workflow:
1. User 1 applies his certificate-based signature using the Certificates tool (Digitally Sign function).
2. User 1 uses the Adobe Sign tool, adding a signature field for user 2 to sign the document.
3. User 2 follows link received from Adobe Sign and opens document in Adobe Sign online.
This is where user 2 cannot apply his certificate-based signature. Same if he downloads the document, as the document is encrypted once user 1 has applied his own certificate-based signature.
You mentionned placing digital signature fields in the document, can you please indicate how to do this once user 1 has already applied his digital signature? I could not find instructions online.
Thanks in advance for your help.
We are sorry for the delay in response.
For more information about sending the documents for signature please refer to the steps provided in the help article https://helpx.adobe.com/in/acrobat/using/send-for-signature.html
Thank you. But it this link is not about certificate-based signatures. So far I was not able to find a solution to my problem. Will keep looking!
I am sorry for the delay in response and for the confusion.
A digital signature always concerns the whole document. And that's the reason why the document must be saved when it is applied. Any subsequent modifications "invalidate" (which is not really the correct term; it would be better to say they make the signature no longer current) the signature, and applying another digital signature "invalidates" the previous one(s).

Hope it will help
All the signatures need to be applied via Adobe Sign. So you create digital signature fields for yourself and the other user, then let Adobe Sign send the document to you for signing, and to the other user for signing. Adobe Sign needs to modify the PDF in a number of ways, so pre-signing doesn't work.
