I have done few days ago.
The webapp shows some information of the file, 2 diferents revisions.
The signer CN, issuer, etc, of each revision.
But the signatures are not being validated against keystore obviously
because in this keystore, there is not installed the same CA certificate
that is needed to validate the signatures.
Anyway, I have upgraded thr adobe reader version of linux and now both
signatures are being correctly validated.
Thank you.
