- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Enterprise deployment and centralized management of PDF security certificates.
- Observed behavior
- Administrators must import trusted certificates from issuing authorities and configure centralized security settings for mass distribution.
Ensure you have the trusted root certificates downloaded from your organization's Certificate Authority (CA) and consult with your IT department regarding specific LDAP integration policies.
Import Trusted Certificates via Acrobat Preferences
Manually add trusted root certificates provided by your issuing authority to validate employee signatures.
For individual users or manual setups, trusted certificates must be imported directly into the application's signature preferences so that signed documents can be properly verified.
Open Adobe Acrobat, go to the 'Edit' menu at the top, and select 'Preferences' from the dropdown list (or press Ctrl+K).
In the Preferences dialog box, select 'Signatures' from the Categories list on the left pane.
Locate the 'Identities & Trusted Certificates' section and click the 'More' button to open the management window.
Select 'Trusted Certificates' on the left side, then click the 'Import' button to browse your computer and add the root certificates downloaded from your issuing authority.

Configure Centralized Security and LDAP Integration
Use Acrobat enterprise administration tools to mass-deploy security settings across the organization.

Frequently Asked Questions
Can Adobe Acrobat generate an enterprise certificate infrastructure independently?
No, Acrobat does not create a centralized certificate infrastructure on its own. It relies entirely on your organization's existing directory, Certificate Authority (CA), and LDAP integration.
Where can I find the Trusted Certificates section in Acrobat?
You can find it by navigating to Edit > Preferences > Signatures. Under the 'Identities & Trusted Certificates' section, click 'More' to manage your public keys and certificates.
How do I deploy certificate settings across multiple employee computers?
For mass distribution, IT administrators should use the Acrobat Enterprise Toolkit (ETK) and configure the necessary registry settings as specified in the official Acrobat Preference Reference guide.
