Hello all :)
On the whole we are loving FreeIPA, Many thanks and much respect to
all involved, we've had a great 12-18 months hassle free use out of it
- it is a fantastically stable trouble free solution... however now
we've run into a small issue we (as mere mortals) are finding it hard
to resolve :-/
We upgraded our ipa servers (3.0.0-42) to Centos 6.6. everything seems
to go well, but one server is behaving oddly. It's likely not an IPA
issue, it also reset it's hostname somehow after the upgrade (it's an
image in an openstack environment)
If anyone has any pointers as to how to debug I'd be hugely
appreciative :)
Two servers, server1.domain.com and server2.domain.com
Server1 can't push data to server2, there are updates and new records
on server1 that do not exist on server2.
from the logs on server1:
[07/Nov/2014:01:33:42 +0000] NSMMReplicationPlugin -
agmt="cn=meToserver2.domain.com" (server2:389): Warning: unable to
send endReplication extended operation (Can't contact LDAP server)

replicate schema: rc=2
[07/Nov/2014:01:33:48 +0000] NSMMReplicationPlugin -
agmt="cn=meToserver2.domain.com" (server2:389): Consumer failed to
replay change (uniqueid (null), CSN (null)): Can't contact LDAP
server(-1). Will retry later.
Try to see
a) Server 1 properly resolves server 2
b) You can connect from server 1 to server 2 using ldapsearch
c) your firewall has proper ports open
d) dirserver on server 2 is actually running
Check logs on server 2 to see whether it actually sees an attempt to
connect, I suspect not, so it is most likely a DNS/FW issue or dir
server is not running on 2.
and the servers:
[root@server1 ~]# ipa-replica-manage list -v `hostname`
Directory Manager password:
server2.domain.com: replica
last init status: None
last init ended: None
last update status: 0 Replica acquired successfully: Incremental
update started
last update ended: 2014-11-07 01:35:58+00:00
[root@server1 ~]#
[root@server2 ~]# ipa-replica-manage list -v `hostname`
Directory Manager password:
server1.domain.com: replica
last init status: None
last init ended: None
last update status: 0 Replica acquired successfully: Incremental
update succeeded
last update ended: 2014-11-07 01:35:43+00:00
[root@server2 ~]#
