had issues in the past with a password storage scheme used by the replica that was not
supported on the master and caused the bind to fail,
https://bugzilla.redhat.com/show_bug.cgi?id=2151071). The list of supported password
storage schemes is available with the following command:

probably hitting the above BZ. There were fixes for multiple versions of 389-ds, we would
need to know your exact versions on the replica and the master to point you to the right
advisory.

Your ipa-ca-install command failed at 2024-03-11T15:05:24Z. Can you check on the master
around this date if there is a connection from replica to master with a BIND attempt that
would be failing? The logs are in /var/log/dirsrv/slapd-YOURDOMAIN/access. Look for
something similar to BIND dn="uid=admin-freeipa-4.xerces.lan,ou=people,o=ipaca".
Then note the conn number and op number and look for the RESULT with the same conn and op,
for instance:
[13/Mar/2024:09:10:01.331583308 +0000] conn=106 op=2 BIND
dn="uid=admin-replica0.ipa.test,ou=people,o=ipaca" method=128 version=3
[13/Mar/2024:09:10:01.355201520 +0000] conn=106 op=2 RESULT err=0 tag=97 nentries=0
wtime=0.000106547 optime=0.023642452 etime=0.023744831
dn="uid=admin-replica0.ipa.test,ou=people,o=ipaca"
The lines may be separated by other logs, and the err=xxx will show if the bind is
successful or failed. err=0 means success, err=49 means invalid credentials.
Yes, it does fail with invalid credentials...
[11/Mar/2024:15:25:34.887970467 +0100] conn=118429 op=2 BIND
dn="uid=admin-freeipa-4.xerces.lan,ou=people,o=ipaca" method=128
version=3
[11/Mar/2024:15:25:34.888893033 +0100] conn=118429 op=2 RESULT err=49
tag=97 nentries=0 wtime=0.000265028 optime=0.000950489
etime=0.001212411 - Invalid credentials
Latest test, states
[13/Mar/2024:10:41:45.063122671 +0100] conn=192008 op=2 RESULT err=49
tag=97 nentries=0 wtime=0.000244892 optime=0.001078282
etime=0.001320065 - No such entry
I did remove it. as in uninstalled freeipa-4 removed the server and
removed that account, just to make sure it was replicated properly...:
