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:

# ipa-replica-manage list

server2.domain.com: master

# ipa-replica-manage list-ruv

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