How can I add private key to the distribution certificate?
Well, I've got my Developer Certificate linked with it's private key. Works Fine. I've downloaded my iOS Profile of distributor, but it says Valid signing identity not found. So I checked my certificates, and exactly, my developer certificate it's linked with its private key but not my distribution certificate. How can I link/add my private keys to this certificate!? Will this solve the problem "Valid Signing identity not found"? Yes, the error you are getting means that there is not a private key on your Mac associated with the distribution certificate you are trying to use to sign the app.
