I *think* the OP can go here,
http://koji.fedoraproject.org/koji/packageinfo?packageID=7925
and pull an f22 binary rpm needed for a previous release, even if it is
no longer in the repositories.  Once it is downloaded, from the
directory where the downloaded package is located, running
dnf -C downgrade sssd-ipa
should downgrade the installed system package with the locally
downloaded package.  I haven't tried this, so it might not work, but is
probably worth a shot.

You'll have to click on an earlier sssd version for f22, and then
download the binary rpm of the package you need, sssd-ipa.  It seems
that sssd is some sort of combination package, containing a bunch of
component packages.
