Use directory servers to store user certificates
Directory servers are commonly used as centralized repositories of identities within an organization. As such, the
server acts as an ideal location to store user certificates in enterprises that use certificate encryption. Directory servers

After you locate a certificate, you can add it to your list of trusted identities so that you don't have to look it up again.
By developing a storage area for trusted certificates, you or a member of your workgroup can facilitate the use of
encryption in the workgroup.
