Verification steps:

[1]  Create an instance using "dc=example,dc=com"
[2]  import the attached LDIF file:  repl-init-100.ldif
[3]  Create another instance and setup MMR replication 
[4]  Copy the mod-emp.sh and doit.sh scripts to the same location.
[5]  Run the doit.sh script
[6]  Check if the server is still running

I repeated steps mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1083272#c2
Server didn't crash, hence marking as VERIFIED.

Looks good from ipa-replica-install side too:
