Hi,
During the installation of one of our FreeIPA replica (with ipa-replica-install), the
process hangs on "No status yet".
Our domain is in domain level 1.
It seems that the script is waiting for an attribute nsds5ReplicaLastInitStatus.
The master server is up & running and we want to have a multimaster environment.
We don't find any error related to the replication process in the log.
The version installed: 4.6.5-11.0.1.el7_7.3
First, the ipa client is correctly installed on the server. Then we use the comment
ipa-replica-install to promote it as IPA server with:
ipa-replica-install -U --principal admin --admin-password $admin_password --domain
domain.com --server server2.domain.com --setup-ca --setup-dns --no-forwarders
--forward-policy=first --no-dnssec-validation --allow-zone-overlap
--reverse-zone=xx.xx.in-addr.arpa --mkhomedir --force-join
In the ipareplica-install.log we just have this:

On the live master, there is a strange behavior also:
It seems the ldap is like in read only mode. For exemple, if I reset the password of an
account, I don’t have any error but nothing happened.
I have also those errors on this server:

But we don’t have any replication because no other servers:

I really don’t know what happened here. Could you help us on that ?
