How to sign a file using a certificate allocated in Active Directo

Hi All,

We are trying to manage certificates wich are allocated in the Active
Directory from any computer.

We can access the certificate, but when trying to sign with it, the system
shows the message:

"The signer's certificate is not valid for signing"

When using that same certificate locally, there's not a problem.

Any comment would be appreciated,

You do not sign with certificate, you sign with corresponding *private key*. The
private key is stored locally, and protected either by DPAPI or by some other
mechanism (smart card for example).
