<div>we are going to have a use case of diskless HPC clients
that will use the IPA for lookups, I was wondering if i can
get rid of the state-fulness of the client configuration as
much as possible as it is more of a cattle than pets use case.
that is i do not need to know that the client is part of the
domain, no need to enroll a node with a certificate. and
services will be mostly hpc mpi and ssh, not required to have
an SSL certificate for secure communication. is it possible to
get rid of the client certificate and the requirements for
clients to enroll? or there are other uses for the certificate
that i am not aware of ?</div>

I think the main problem is making sure that the client can connect
to IPA server.<br>
You can elect to not use ipa-client and just copy configuration
files. The problem is that SSSD requires some type of the
authentication to get to IPA as a host to do the lookups.<br>
So this connection must be authenticated. Since you want it to be
stateless you do not want to manage keys or certs the only option
(which I really do not like) is to use bind password in a file for
LDAP connection. You would probably use the same unprivileged
account for this bind. However when we get to 4.x you would need to
adjust permissions on the server side to make sure that proper read
permissions are granted. Having a password in a file is a security
risk so make sure it is not leaked.<br>
