I think there was an attempt to implement this.
I found this ticket.
Are you saying it is not working?
This ticket was implemented early on, but as the SSSD grew in
complexity, we removed this functionality because it was causing issues.
There's some ongoing discussion about how to properly handle this going
forward, but it's a complicated problem. Most notably because each
different data provider backend has to be able to reload its own
configuration, and this can't necessarily be done live in some cases.
One suggestion that's been proposed is that on reload, we have the
monitor reload its configuration and then just kill and restart all of
the responders and providers. This would accomplish the goal, but it
would also interrupt any requests that are occurring at the same time.
Making the SSSD reload all its configurations without interrupting
in-progress requests is a fairly complicated undertaking. And no matter
what, we still have to be able to account for the [sssd] section
changing values for the "services" and "domains" entries, which will
force a shutdown and/or startup of some of the helper processes anyway.
Delivering value year after year.
