Comment 1 Noriko Hosoi 2014-07-09 23:24:24 UTC

Hard to reproduce the problem.
IPA + MMR + replication conflict, then running consumer initialization makes the server crash.
Fix was verified at the customer site.
Sanity check only?

Comment 3 Amita Sharma 2014-12-18 14:05:14 UTC

Based on comment https://bugzilla.redhat.com/show_bug.cgi?id=1118069#c1
I have verified MMR functions well with latest build.
Marking bug as VERIFIED.
