If users of your AEM forms installation use the data capture functionality of Content Services (Deprecated), it is recommended that you create a role with read-only access for these users.
*note: Adobe® LiveCycle® Content Services ES (Deprecated) is a content management system installed with LiveCycle. It enables users to design, manage, monitor, and optimize human-centric processes. Content Services (Deprecated) support ends on 12/31/2014.
Data capture requires that you assign a user role to access the SampleReaderExtensionsCredential. You may assign the standard Trust Administrator role, but consider that this role gives general, non-administrative users the powerful administrator privileges that control the PKI Trust settings and manage PKI Credentials, which could compromise the security of your AEM forms installation in a production environment. It is recommended that the AEM forms system administrator create a role that grants only read-only access to the Trust Store, and assign this new role to non-administrator users who use data capture.
