How to Implement a Server for Roaming Digital IDs in PDF Editors
Question details
The user is looking for guidance on implementing a roaming digital ID server, specifically asking how to configure a non-preferred Cloud Signature Consortium (CSC) compliant service within Adobe Acrobat Reader.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Deploying an enterprise-level digital signature system where employees need to access their certificate credentials from various locations using roaming IDs.
- Observed behavior
- Integrating a CSC-compliant provider that is not on the default preferred trust list lacks clear implementation steps for server setup and application configuration.
Ensure you have administrative access to your organization's identity infrastructure and verify whether your chosen certificate provider fully supports the Cloud Signature Consortium (CSC) protocol.
Verify Architecture and CSC Requirements
Determine the required integration methods and trust configurations for your specific certificate provider before server implementation.
Deploying a roaming digital ID server requires strict alignment with supported protocols. If you are using a Cloud Signature Consortium (CSC) service, the PDF reader must support the provider's integration method natively or through a plugin.
Consult Adobe's enterprise deployment guidelines for roaming digital ID server implementation specific to your version of Acrobat or Reader.
Contact your certificate provider to verify if their CSC protocol implementation requires any custom plugins or specific API endpoints to communicate with PDF software.
Establish strict server-side policies outlining how digital certificates, private keys, user authentication, permissions, backups, and certificate revocation lists (CRLs) will be managed.
If your provider is not on the Adobe Approved Trust List (AATL), manually configure the PDF reader to trust the provider's root certificate by importing it into the Trusted Identities settings.

Add a Roaming ID Account Manually
Configure the PDF reader to connect to your custom roaming ID server using the software's identity management settings.
Sign PDFs Securely with WPS Office
While configuring enterprise roaming ID servers can be complex, WPS Office offers a straightforward, built-in solution for applying digital signatures and certificates to your PDF documents locally.
- 1. Open the Document: Launch WPS Office and open the PDF document you need to sign.
- 2. Navigate to the Protect Tab: Click on the 'Protect' tab located in the top ribbon.
- 3. Select Digital Signature: Click the 'Sign Document' or 'Digital Signature' button.
- 4. Apply Certificate: Import your digital certificate file, enter your secure password, and place the signature field on the document.

Frequently Asked Questions
What is a roaming digital ID?
A roaming digital ID is a secure digital certificate stored on a centralized server rather than locally on a user's computer. This allows users to access their digital signatures from multiple locations and devices.
Can I use a CSC-compliant provider that is not on the preferred list?
Yes, but it requires manual configuration. The root certificate of the non-preferred provider must be manually imported and set to trusted within the application's Trusted Identities settings so that signatures validate correctly.
Why are my roaming digital signatures showing as invalid?
This typically occurs if the server connection fails, the certificate has expired, or the certificate authority (CA) issuing the roaming ID is not included in the PDF reader's list of trusted identities.
What infrastructure is required for a roaming ID server?
A roaming ID server requires secure user authentication mechanisms, encrypted storage for private keys, automated backup systems, and support for standard integration protocols such as the Cloud Signature Consortium (CSC).
