Status of certificate requests

Requests for certificates are kept in a request database while they are active. This is from the moment they are created until an event occurs that causes them to be deleted. The following table summarizes possible statuses. During the time period when a certificate request is active, it can have only one of the following statuses at a time:

Table 1. Statuses of certificate requests
Status	Meaning
`Pending Approval`	The request requires administrative approval. No action has been taken on the request yet.
`Approved`	The administrator explicitly approved the request or it was submitted as an auto-approved certificate request. The actual certificate might or might not have been created at this point.
`Completed`	The certificate has been issued and the requestor has retrieved it. This is a final state.
`Preregistered`	The certificate request is from a preregistered Simple Certificate Enrollment Protocol (SCEP) client.
`Rejected`	The administrator rejected the request, and the requestor has not been informed of this action (because the user has not tried to retrieve the certificate).
`Rejected, User notified`	The administrator rejected the request and the requestor has been informed of this action when attempting to retrieve the certificate. This is a final state.

A request is deleted from the request database when the administrator explicitly deletes it or when the request expires. This expiration time period is configurable and varies depending on whether the request was finalized or not.
