In cases where replication is effected by latency, we need to have a better means of handling the replication conversion to gssapi.

Otherwise the code errors out during a replica-install at line 550 of /usr/lib/python2.7/site-packages/ipaserver/install/replication.py

I've verified that inserting time.sleep(300) seems to work around the problem, I suspect a loop may be necessary to verify that the modification was replicated before attempting to move forward in the code.
