 // Test for bug 58437.
 // This certificate will expire on 2011-12-21. The test will still
 // pass if error == ERR_CERT_DATE_INVALID.
 // This test is DISABLED because it appears that we cannot do
 // certificate revocation checking when running all of the net unit tests.
 // This test passes when run individually, but when run with all of the net
 // unit tests, the call to PKIXVerifyCert returns the NSS error -8180, which is
 // SEC_ERROR_REVOKED_CERTIFICATE. This indicates a lack of revocation
 // status, i.e. that the revocation check is failing for some reason.
