Interesting ... yeah, it's totally possible that those combinations of
features may not play nicely with eachother, because the
DocExpirationUpdateProcessor initiates it's own solr requests under the
covers - it has no "original request" to copy authentication credentials

Can you please file a jira about this?

The obvious workaround is to use your own externally scheduled cronjob to
just send a deleteByQuery (with the neccessary credentials) using a date
range on the timestamp field (that's all DocExpirationUpdateProcessor does
under the covers)

I suspect that we need to add a standard way for plugins that want to
"initiate" cluster requests to ask Solr to pre-populate it with required
info (like credentials) and then DocExpirationUpdateProcessor could use
that ...

(i wonder if something like that was already added when authentication was
introduced but folks forgot to updated DocExpirationUpdateProcessor to use
it? ... i wonder how things like autoCommit and overseer initiated core
admin commands get correct auth credentials today?)

: All,
: I'm facing some difficulties utilizing both document expiration and the
: security plug-ins in Solr 5.5.0. Looking at the log file for the shard1
: leader, I can see it initiate the delete process. Unfortunately, it
: rapidly emits errors for all of the other nodes, as those requests get
: rejected for lack of credentials (note that I've replaced collection name,
: hostnames, ports):
