We have _many_ hosts in a cluster, so this is not practical on a per host basis. I single line command we could bulk execute on each of them to retrieve the key would be preferred.

In the freeIPA git repo there is, in the spec file, a variable that allows you to compile only the client bits IIRC. You should be able to compile that for SLES.
