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

replica since it was quite straightforward when I first set it up
(what could go wrong, right?)
What is your version of 389-ds-base? rpm -q 389-ds-base
What is in your dirsrv errors log? /var/log/dirsrv/slapd-DOMAIN-TLD/errors
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).

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!
