Sorry that it took me that long to answer. I just got the green marks without much trouble, both in Adobe Acrobat 9.5.5 and in Adobe Reader XI 11.0.3. In case of your latest document, signed_Technical_data_TS_OCSP.pdf <http://itext-general.2136553.n4.nabble.com/file/n4658540/signed_Technical_data_TS_OCSP.pdf> I only needed to trust the root certificate in the viewer. I tried it both ways: 1. Using "Manage Trusted Identities" (or so I assume as I'm using the software with German localization) I added the root certificate ( RootCA5_DER.cer <http://itext-general.2136553.n4.nabble.com/file/n4658540/RootCA5_DER.cer> ) to the certificates known to Adobe Acrobat / Reader and checked the checkbox for the use of the certificate as trusted root. 2. Using the certificate details view from the signature properties dialog I selected the root certificate and chose to trust it. (This was only possible because you included the whole certificate chain in the signature container.) Either way I got: <http://itext-general.2136553.n4.nabble.com/file/n4658599/signed_Technical_data_TS_OCSP.png> In case of your older documents, e.g. signed_Technical_data_new_TS_OCSP.pdf <http://itext-general.2136553.n4.nabble.com/file/n4658514/signed_Technical_data_new_TS_OCSP.pdf> I additionally had to add the intermediate certificate ( OperCA5QES_DER.cer <http://itext-general.2136553.n4.nabble.com/file/n4658540/OperCA5QES_DER.cer> ) using "Manage Trusted Identities", but ONLY add, no need to set any special trust. <http://itext-general.2136553.n4.nabble.com/file/n4658599/signed_Technical_data_new_TS_OCSP.png> Valentin Ivanov wrote > I did it in both places.

After adding the certificates to the Adobe Reader store, have you checked the "trusted root" checkbox?
