When a user is signing a form, the digital certificates that are installed (in Acrobat) on the computer being used to sign the PDF will be available to be used to create the signature. If only the "bosses" certificate is on the machine, this will be the only on available. Make sure all certificate that could be used to sign are installed on the machine being used to sign.
This screen shot is from the security settings in Acrobat, it shows multiple certifcates are installed.
And here is the signature dialog with the option to use one of the installed certificates on the machine...
Hope this helps.
Thank you, Steve. Your instructions seem to be for electronic IDs that
have a third-party certificate. Ours don't. However, I'll see if we
can edit to create the necessary additional signatures.
It doesn't matter if the certificates are issued by a third party or if they are "self-signed". The same concept applys for "self-signed" certificates that you can create with Acrobat.
Thank you again, Steve. I was just about to let you know that I tried
it, and it worked. I easily created three different signatures myself.
Now I know how to instruct our administrative assistants to do the same.
I really appreciate your help.
