[Freeipa-users] IPA Replica Issues (Total update abortedLDAP error: Can't contact LDAP server)

I've had a replica working with FreeIPA 3.2.1 for awhile. After upgrading
to 3.3.4, the replica wouldn't recognize my admin login anymore. After much
troubleshooting, I decided to try to redo the replica since it was quite
straightforward when I first set it up (what could go wrong, right?)

Unfortunately, I've spent most of my day trying to get the replica to work
this time. I've tried turning off all firewalls on both machines, rebooting
both machines, upgrading all packages on both machines (both are running
Fedora 19), reinstalling FreeIPA packages, and several other things, but I
keep getting stuck at the same step (see output below).

Failed to start replication
=================================================================

I've confirmed that I can do ldapsearch from each machine to the other one
for the replica status records (through ldap and ldaps), so I know that
they can communicate. Trouble is, something behind the scenes is throwing
the status error (as seen in the nsds5ReplicaLastInitStatus attribute).

I'd really love for someone to help out with this, as I can't afford
another entire night trying to figure this out. Thanks in advance!
