From now on, PDFs signed by our certificates will be recognized in your Adobe Acrobat Reader.

(Note: in Acrobat Reader 7, non-derived Adobe root certificates do not inherit trust settings. It may be necessary to set permissions on each root generating end-entity certificates).

Error message: "The selected certificate has errors: invalid policy constraint".

This error occurs when a document is signed with a certificate issued under TBS X509 CA Persona 3 (RSA) and recent versions of Adobe that recognize the USERTrust root as AATL. Our certificate does not have AATL recognition, so the error appears.

For the signature to appear as valid by Adobe, a RGS certificate is required **: see our comparison table
