[Freeipa-users] Freeipa 4.3.0 replica installation fails with DuplicateEntry: This entry already exists

Wow, strange stuff, the search I linked in the last email for our non working dev environment seems short some entries.

For comparison, here is the same search run against our currently working prod environment.

As you can see, our prod environment has a huge aci on the config tree.

 For reference, our prod and dev environments were identical (FreeIPA 4.1.4/CentOS7.1) before I updated our dev environment to CentOS7.2/FreeIPA4.2.0 -> Fedora23/FreeIPA4.2.3 -> Fedora23/FreeIPA4.3.0.  So at some point during this upgrade process I assume maybe one of the installers deleted acis on our tree?  That sounds like the kind of thing that would happen when introducing the new domain level functionality in 4.3, like if someone accidentally thought "oh this replica branch is now in a globally replicated section, we can remove these acis for this local stuff..." and then put that logic into the installer or something...

The real question is, is there some good way of getting those aci's back, like a fixaci command?

Prod aci's that do work for comparison

You almost got it.  You left out the most important part, at the end of the command, specifying the "aci" attribute:
