![]() The required elements for establishing the validity of a signature include the signing certificate chain, certificate revocation status, and possibly a timestamp. Embedding these elements can occur when the document is signed, or after signature creation. LTV requires embedding signature validation in the signed PDF. Long-term signature validation (LTV) allows you to check the validity of a signature long after the document was signed. Without conforming revocation status, the signature cannot be validated. Once a certificate expires, the issuing authority is no longer responsible for providing revocation status on that certificate. This limitation occurs because certificates related to the signature eventually expire or are revoked. Without certain information added to the PDF, a signature can be validated for only a limited time. Select Directory Servers in the left-hand list.Ĭonfigure the LDAP server settings in the Edit Directory Server dialog: For 11.0, choose Preferences > Security > Configure Server Settings > More. To configure a directory server manually: Post-installation instruction distribution: Tell users how to configure the server manually. This method is useful for configuration of an existing installation. Users can automatically import the settings by double clicking on the file. Post-installation setting distribution: Export server configuration details in an acrobatsecuritysettings or FDF file and distribute it across the organization. The process involves configuring a directory server in your template installation and using the Wizard to copy the directories.acrodata file to the tuned installer. Pre-installation (Recommended): Tune the installer with the Adobe Customization Wizard prior to application deployment. Search the Preference Reference for LDAP for a complete list of registry-level options.Īdministrators can configure directory servers in several ways: While the product ships with the VeriSign Internet Directory Service as the default server (viewable in the Security Settings console), admins typically set an internal server as the default. End users leverage these certificates in certificate-based security workflows when they encrypt a document as wellas when validating a signature. Acrobat products can use LDAP servers as x.509 public key certificate repositories. Many organizations use Lightweight Directory Access Protocol (LDAP) directory servers to enable LDAP-aware clients to retrieve email addresses, network services, software directories, and so on. Review the application security preferences to secure your application, data, and network. Review the Preference Reference for additional other signature-related preferences you may need. Tune Certificate Revocation Checks for OCSP, CRL, and the interaction of each. You may also want to create enterprise signature appearances as described in Custom Signature Appearances.Ĭonfigure the Timestamp Servers list, defaults, and usage.Ĭonfigure Signature Validation logging, revocation checking, service providers, and so on. ![]() Set up the Signing Environment requirements, workflow, and method. Additional settings and details appear in the Preference ReferenceĮstablish PKI Trust via CDS, AATL, EUTL, or local trust lists. Review this list to craft the installation you need. The product ships with default settings, and all of these steps are optional. For example, an application has a default timestamp server configured, a certificate contains an OID that specifies a different timestamp server, and a seed value specifies a third timestamp server for a particular signature field in this case, the seed value timestamp server is used. ![]() In general, the smaller the scope of the variable, the more controlling it is. Understand how workflow behavior is determined by registry configuration, certificate extensions, and seed values. For example, use its Files and Folders feature to deploy signature-related acrodata files.ĭeploy the application as described in the Administration Guide. Use the Wizard’s UI to set additional preferences. This is the easiest way to create new settings as well as leverage existing installs. Use the Wizard to copy the registry settings and files from your installed application to the new installer. Set the preferences in the Security and Signatures categories. Install the application and configure it via the UI. Learn about setting registry and plist preferences, including feature locking, paths, the relationship between the UI and the registry, and other topics. To leverage Acrobat’s rich digital signature capabilities, follow these best practices:įamiliarize yourself with this guide, the Preference Reference, and the Customization Wizard.
