In Adobe Reader, under Digital ID and Trusted Certificate Settings, I have a Digital ID issued by my domain's CA, with the storage mechanism of Windows Certificate Store.
The trust settings for this certificate have all options with a Green tick, and the CA is listed under Trusted Certificates
This Digital ID is intended usage: Digital Signature, Encrypt Keys and Client Authentication
For some reason, when i try to Sign with Certificate, the option to use this Digital ID does not appear, Adobe Reader prompts me to create a new Digital ID
If i create a new Digital ID using Windows Certificate Store, then i am able to use it to sign my document
Why can i not use the certificate generated by my domains CA to sign a PDF document? Is there a group policy setting that needs to be enabled?
Please note that the Microsoft Word digital signature works perfectly, and I am able to use the certificate assigned by my domain CA (the same one showing in Adobe) to verify and sign documents in Word
