Thanks!

Hi!

I run IPA on CentOS 7. I have two servers (Leader and Replica, though they changed roles couple times because of reinstalls), had ca and domain services on both of them, replication set up and working. I had to switch off Replica for 6 months. When I turned it on recently, I found expired certificates, couldn't fix them easily and lost the old Replica - at least I concluded it was easier to reinstate the Replica than to detangle the mess I made while was trying to back out of outdated certs. I hit the same error as I do now though - Invalid Credentials (49).

So I did the following:

1) on Replica - ipa-server-install --uninstall.
2) on Leader - ipa-replica-manage del --force --clean Replica.
3) removed obsolete replication agreement meToReplica from Leader.
4) removed all traces of Replica from DNS.

Then I started to install Replica from scratch:

1) ipa-client-install
2) ipa-replica-install --setup-ca --setup-dns --forwarder X --forwarder Y

Installation consistently fails with:

'''
Run connection check to master
Connection check OK
Configuring directory server (dirsrv). Estimated time: 30 seconds
<...>
  [29/42]: setting up initial replication
Starting replication, please wait until this has completed.
Update in progress, 16 seconds elapsed
[ldap://Leader:389] reports: Update failed! Status: [Error (49)  - LDAP error: Invalid credentials]

  [error] RuntimeError: Failed to start replication
'''

Logs from Leader, /var/log/dirsrv/slapd-DOMAIN/errors:

'''
[<DATE>] - ERR - NSMMReplicationPlugin - bind_and_check_pwp - agmt="cn=meToReplica.domain" (Replica:389) - Replication bind with GSSAPI auth failed: LDAP error 49 (Invalid credentials) ()
"""

I verified clocks on both Replica and Leader - they show the same time (within 1-2 seconds diff window). In fact, at some point I had Replica taking time straight from Leader, before they were set up to use the other common source. I dumped traffic between Leader and Replica - indeed, Leader tried to authenticate on Replica and Replica replies "Invalid credentials".

I googled this error and read multiple email threads but nothing helped so far. Replica works fine as IPA client but can't get promoted to a replica. 

What am I missing?

Thanks!
