Description of problem:
Created replica package on master, installed replica. But because of a bug in
bind-dyndb-ldap, replica install failed when using setup-dns (bug 748901). So
using same replica package, or after generating new package, replica install
still failed when not using setup-dns (avoid this option to workaround bug
748901). This time with error that it "Failed to start replication"

Had to run:
ipa-replica-manage del ipa-replica.testrelm --force
to delete/clean any replication agreement, and then was able to install
successfully.

Would be nice to have an error that specifically suggested to delete the
replication agreement to be able to install successfully.

ipareplica-install.log had:
