### No OCSP support, yet
Vault's architecture does not currently allow for a binary protocol such as
OCSP to be supported by a backend. As such, you should configure your software
to use CRLs for revocation information, with a caching lifetime that feels good
to you. Since you are following the advice above about keeping lifetimes short
(right?), CRLs should not grow too large, however, you can configure alternate
CRL and/or OCSP servers using `config/urls` if you wish.
If you are using issued certificates for client authentication to Vault, note
that as of 0.4, the `cert` authentication endpoint supports being pushed CRLs,
but it cannot read CRLs directly from this backend.

This sets the allowed key usage constraint on issued certificates. This
