/*
 * Test Name: request_key02
 *
 * Description:
 * 1) request_key(2) fails if no matching key was found.
 * 2) request_key(2) fails if A revoked key was found.
 * 3) request_key(2) fails if An expired key was found.
 *
 * Expected Result:
 * 1) request_key(2) should return -1 and set errno to ENOKEY.
 * 2) request_key(2) should return -1 and set errno to EKEYREVOKED.
 * 3) request_key(2) should return -1 and set errno to EKEYEXPIRED.
