USING ACROBAT 9 STANDARD 224 Security 4 In the Trust tab, select any of the following items to trust this certificate for: Use This Certificate As A Trusted Root Trusts signatures created directly by this certificate. The root certificate is the originating authority in a chain of certificate authorities that issued the certificate. By trusting the root certificate, you trust all certificates issued by that certificate authority. Signed Documents Or Data Acknowledges the identity of the signer. Certified Documents Trusts documents in which the author has certified the document with a signature. You trust the signer for certifying documents, and you accept actions that the certified document takes. When Certified Documents is selected, the following options are available: Dynamic Content Allows movies, sound, and other dynamic elements to play in a certified document. Embedded High Privilege JavaScript Allows privileged JavaScript embedded in PDF files to run. JavaScript files can be used in malicious ways. It is prudent to select this option only when necessary on certificates you trust.

Use directory servers to store user certificates Directory servers are commonly used as centralized repositories of identities within an organization. As such, the server acts as an ideal location to store user certificates in enterprises that use certificate encryption. Directory servers help you locate certificates from network servers, including LDAP (Lightweight Directory Access Protocol) servers. After you locate a certificate, you can add it to your list of trusted identities so that you don't have to look it up again. By developing a storage area for trusted certificates, you or a member of your workgroup can facilitate the use of encryption in the workgroup. For more information about directory servers, see Digital Signature User Guide for Adobe Acrobat and Adobe Reader (PDF) at www.adobe.com/go/learn_acr_security_en.
