Since 389-ds-base-1.4.4.6-1 landed in Rawhide, and when testing it as an update for F33 (and when testing 1.4.3.14-1 as an update for F32), FreeIPA server deployment fails with dirsrv errors like this:

mreynolds says he knows what this is, but I'm filing a bug for tracking. I believe from context that https://github.com/389ds/389-ds-base/commit/67c8b8702a249cb0ef1ebf49b6e87056cd5339f6 is intended to fix this; I'm currently testing an F33 scratch build with that fix backported. So far it seems like it may fix server deployment, but there is still a problem with replica deployment. ipa-replica-install fails with this error:

and the dirsrv logs show this error around the same time:
