I have a signed PDF that is failing validation, the error ‘At least one signature has problems’ is appearing. The error details, “There were errors encountered while building the certificate chain to certifcate designated as a trusted anchor. Revocation checks were therefore not performed on this certificate. See the message at the bottom of this dialog for an explanation.” appear in the Revocation Tab. The signer’s cert has expired, but has not been revoked. I have other singed documents where the signing cert has expired, but I do not get the same errors. Any idea what the issue is or where to look?
Anyone in Adobe willing to look into this, I can send on the PDF in question if you want?
