That's because your authz-regexp is wrong. You mapped "cn=localhost" but when
using SASL EXTERNAL, the user's DN is the complete certificate DN. In your
The reason this didn't break replication is because in this test, everything
has anonymous read access so the consumer was able to pull what it needed.

I didn't get this far because your test certificate is now expired. I guess I
can substitute some other certs and look at it again, but I think the core
issue is your misconfigured authz-regexp.

Better to rename your scripts when you modify one of our existing ones. E.g.
test999-xxxxxx and just create new data files instead of modifying ours.
