Thanks! Everything works now, I just found two issues in error reporting.

I set up three masters like this:

$ ipa-replica-manage dnarange-show
vm-084.idm.lab.eng.brq.redhat.com: 1109050002-1109099999
vm-081.idm.lab.eng.brq.redhat.com: 1109012501-1109024999
vm-079.idm.lab.eng.brq.redhat.com: 1109025001-1109049999
$ ipa-replica-manage dnanextrange-show
vm-084.idm.lab.eng.brq.redhat.com: 1109000000-1109012499
vm-081.idm.lab.eng.brq.redhat.com: 1109190000-1109190001
vm-079.idm.lab.eng.brq.redhat.com: No on-deck range set

vm-079 is git master, the other two have the patch applied.

Now when I deleted vm-081, there was no indication which ranges I lost:

vm-084$ ipa-replica-manage del vm-081.idm.lab.eng.brq.redhat.com
Deleting a master is irreversible.
To reconnect to the remote master you will need to prepare a new replica 
file
and re-install.
Continue to delete? [no]: y

One more detail: Ranges where start==end are invalid. We should fail the 
same way as for start>end.
