Hi all
I have two centos 8 servers. One is installed and configured as master and AD trust controller. The second one, I'm trying to configure it as a replica, but what ever I do, the replica server fails to start.
Environment : OS - CentOS Linux release 8.1.1911 (Core) ipa-server: ipa-server-4.8.0-13.module_el8.1.0+265+e1e65be4.x86_64
Replica install is started with : #ipa-replica-install -v --principal admin -p XXXXX --domain ipamaster01.example.com --server ipamaster01.example.com --setup-ca --setup-adtrust
The client install goes well, but the server stops at :
Starting replication, please wait until this has completed. Update in progress, 15 seconds elapsed [ldap://ipamaster01.example.com:389] reports: Update failed! Status: [Error (-2) - LDAP error: Local error - no response received]
On the ipareplica-install.log, last entries are:

I can query both ldap servers on the master and replica with :
ldapsearch -h ldap://ipamaster01.example.com -p 389 -Y GSSAPI -b "" -s base -W ldapsearch -h ldap://ipareplica01.example.com -p 389 -Y GSSAPI -b "" -s base -W
in this point, I'm really run out of options. Could someone tell me what I'm doing wrong?
Cheers Alex
