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.
