I believe this is known already, but wanted a bug # to track it (so I can link to the issue from openQA). FreeIPA cannot be properly installed in current Fedora Rawhide due to dependency issues with Samba, e.g. freeipa-server-trust-ad depending on libsmbldap.so.0 (the soname was bumped to libsmbldap.so.2 in Samba 4.7). It seems an attempt to rebuild against Samba 4.7 was made, but failed on ppc64le: https://koji.fedoraproject.org/koji/buildinfo?buildID=916829 This very likely constitutes an Alpha blocker as it will probably result in FreeIPA not being installable (can't tell for sure right now as the test fails earlier, due to a bug in rolekit).
All patches are committed to freeipa package git already. We are waiting for gcc/glibc fixes to be done with ifunc crashes on ppc64le. Without that there is no way to rebuild FreeIPA in rawhide. However, even when that rebuild completes, FreeIPA will still be non-functioning on Rawhide, thanks to curl dropping support for NSS. See https://bugzilla.redhat.com/show_bug.cgi?id=1455561#c5 for details.
I was successful in completing Rawhide build after bug 1470115 was solved. I'm closing this bug as the package is rebuilt. However, my comment #1 stands but there is another bug for that.
