Certificate Services Question

Hi,

When certificate services has been installed as either enterprise or
standalone what is actually held in the database.

If a user is issued a cert for example, in his profile I presume he will
have a cert containing his public key & will also have corresponding a
private key in his profile.

However, what's contained in the ca database regards keys & certs for the
user? Is it just the users cert & public key that's held in the ca database
?

Cheers,
