this looks like a database/index corruption. There are traces for theldapprincipal for auth02in the database, but teh index and the databaseare inconsistent. you can try to reindex teh database and see if this helps:

db2index.pl -D ... -w .. -Z <instance> -t entryrdn  #only this index
or
db2index.pl -D ... -w .. -Z <instance> # full reindex

Hello Rob,

thanks for your explanations. I followed your hints and did a complete 
uninstall and started over with a fresh installation. I ended up with exactly 
the same error as the first time...

I did the following steps:


auth01$ ipa-replica-manage del auth02

auth02$ ipa-server-install --uninstall

auth01$ ipa-replica-prepare --ip-address 192.168.210.181 auth02.intern.eu

auth02$ ipa-replica-install --setup-dns --setup-ca --forwarder 192.168.210.40 
/root/replica-info-auth02.intern.eu.gpg


Are there other logfiles i can check for more specific errors?

you should have a look to the DS error logs in /var/log/dirsrv on both
instances

Does nobody have an idea whats the problem here?

TL;DR you are best off deleting this failed replica install and trying
again.

Initial replication is done over TLS. When replication is completed both
sides of the agreement are converted to using GSSAPI and both ldap
principals are needed to do this. Given that replication just completed
both principals should be available but rarely one is not (hence the
vague-ish error message).

In this case the new ldap principal for the new replica wasn't found on
the remote master so things blew up.

There is no continuing the installation after this type of failure so
you'll need to remove the failed install as a master on auth01
(ipa-replica-manage del auth02...) and then run ipa-server-install
--uninstall on autho02 and try again.

Thanks

Hello,


i have an existing FreeIPA installation (4.2.0) on CentOS 7.2 and i'm
trying to add an replication partner.


During the installation i got the following error:


###

     [6/8]: enable GSSAPI for replication

     [error] RuntimeError: One of the ldap service principals is missing.
Replication agreement cannot be converted.

Your system may be partly configured.

Run /usr/sbin/ipa-server-install --uninstall to clean up.


ipa.ipapython.install.cli.install_tool(Replica): ERROR    One of the
ldap service principals is missing. Replication agreement cannot be
converted.

The installation Log shows the following:
