How can signserver CE support LTV-enabled when signed pdf-file being opened with Adobe after signing with PDFSigner?

[tommy-inteluck]

I have arleady used CA cetificate with AATL and configured TSA_URL when signing with PDFSigner.
After that, when I opened the file with Adobe, and the signature can pass AATL validation and secure timestamp validation.
But still showed 'LTV not enabled'.

Can signserver CE support that. If so , what am I missing while signing whith PDFSigner?

I think for the PDF to be considered LTV-enabled, the signature needs to include revocation information. I.e. the signing certificate needs to include revocation information (either a URL for an OCSP responder providing revocation lookup for the issuing CA, or a link to a CRL download for revocation list).

Hi nicoveiguela,
You can check this AATL members in this link: https://helpx.adobe.com/acrobat/kb/approved-trust-list1.html
You can buy the certificate from any provider in this member list. Maybe you would like to chose a provider in your country.

Thank you Tommy,

I was wondering which one you bought and if you got it online? Im asking because it has been hard to find a certificate with out hardware device.

I use WoTrus, you can check it in the CN section of AATL list.
I don't know if it has English version website for its products.

Hi Tommy,

To LTV enabled you need to timestamp signed pdf content and include into pdf signature with pdf, then Adobe can check LTV enabled or not.
