"""
I also do believe that this PR breaks what was fixed by https://pagure.io/SSSD/sssd/c/cf4f5e0

I think we can either introduce an option to specify how SSSD should work in this particular case or explain in some  document (maybe ipa man pages about override or knowledge base article?) how SSSD behaves. I do not think this is described anywhere currently.
