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/ipa02.example.com at EXAMPLE.COM] 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/ipa02.example.com at EXAMPLE.COM

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:
http://www.freeipa.org/page/Troubleshooting#DNS_Issues

HTH,
Martin
