FreeIPA and Confd

How we can interact with FreeIPA , through Confd

That depends a lot on what you mean by “interact with”. In any case you will need to start with a data model for the part that you want to “interact with”, followed by some code that implements the actual interaction. But before all that, you should probably have a look at the documentation and examples that are distributed with ConfD, especially at parts dedicated to CDB and CDB subscribers - I would assume you will need that.

Thanks a lot for the insight and guidance, I am reviewing those videos, Right now I am trying to test ssh authentication from a client (centos) machine through confd , and then later with PAM.
Again greatly appreciated
