You are almost right, the box only needs to lookup users/groups from
another IPA server for environment admins. The "LDAP Only" on this IPA
server (and client) won't do anything on the whole network layer, only
some webapp is talking to it and use users don't have anything todo
with the network at all but I think it's nice when I don't have to
maintain my local users there to login to the box for maintenance so I
thought it would be nice when SSSD checked my default IPA-environment
server for that.
