Hi Martin, thanks for the help.
Yes, I already did that test. Created a user on ipa01 (master), then he
appeared on ipa02 (replica), in the replica, I modified his email address, it
appeared back on master. Still, I cannot create a brand new user (or POSIX
group) on ipa02.
[root@ipa01 ~]# ipactl status

[root@ipa02 ~]# ipactl status

DNS is OK, resolving FQDN of both master and replica forward and reverse.

Hello Bruno,
I saw the logs you sent to Dmitri. It seems to me that the replication link is
broken, thus replica DNA plugin cannot acquire DNA ranges from master, thus it
has no available range, thus adding users fails as DS cannot allocate UID and
GID.
I think your replication will be broken as well, did you verify that users you
delete/modify on replica are also deleted/modified on master?
I think the root cause is this log:
[13/Feb/2014:15:31:11 -0200] set_krb5_creds - Could not get initial credentials
for principal [ldap/[email protected]] in keytab
[FILE:/etc/dirsrv/ds.keytab]: -1765328228 (Cannot contact any KDC for requested
realm)
Is your KDC running?
[replica] # ipactl status
You can also try to kinit manually to debug:
[replica] # kinit -kt /etc/dirsrv/ds.keytab ldap/[email protected]
If it does not succeed, neither it'd succeed for the DS.
I would also recommend checking that DNS is sane. You can find some pointers
here:

Martin
