Remote means that there is a PKCS#11 library that can be loaded into a

and always talk to a local service like SSSD rather than have a remote
interface. In this case SSSD on the server can talk to the vault or
IPA LDAP directly and all consumers would use PKCS#11 interface
exposed by SSSD
Something like this...
Yes this is the setting we are discussing, the actual specific
discussion is how SSSD gets the information.
Honza proposed to use a PKCS#11-like schema to store data in LDAP given
DNS will need something similar, however the more we wandered into the
discussion the more I got convinced the Vault is probably a better place
to store this material than the LDAP tree itself at least for prvate
keys.
I only proposed something that would work for my needs (i.e. storing
certificates and associated trust policy) and would be ready for 4.0.
Can you say the same thing about the vault?
For public key material only though I am not sure a pkcs#11 schema will
necessarily be useful. It might, but we do not use it for public SSH
keys. And we also already have schema for public User or Servers X509
certs.
Support for SSH public keys was implemented like 2 years ago, way before
any talk about the vault or PKCS#11 even started. As for certs, the
proposed schema works on top of RFC 4523, which is the cert schema you
mention.
We need to define something for DNS public keys, but they are already
published in DNS Records too if I am not wrong, would that be sufficient
as a storage for the public part ? I am assuming the private keys are
stored in the Vault and they can be files in the format used by bind ?
So the information would be scattered in different places, using
different formats and accessed using different protocols? I'm fine with
that, but it is way beyond my original idea, so please let whoever is in
charge of the vault implement the PKCS#11 module themselves.
Simo.
