[SSSD-users] Can I have sssd manage known_hosts with LDAP?

Hello all, I've been trying (and failing) to configure sssd to use LDAP to retrieve hosts' public SSH keys. I'd like to ask if this is possible with LDAP at all, or this feature is only supported with FreeIPA. If yes, what search filter does sssd use to lookup keys in LDAP? I'm using the sshPublicKey attribute for both people and machines in my LDAP schema, but I can't figure out what attribute is checked to determine the hostname. User ssh public key retrieval works fine in my configuration. I'm using sssd 1.15 which ships with debian stretch. Thanks! BR, George
