Review Comment:
I tried it and got a stack overflow. Here is what happens:
`EmbeddedSolrServer#request ` uses `SolrRequestParsers#buildRequestFrom` to
obtain a`SolrQueryRequest req`. It then calls
`SolrRequestInfo.setRequestInfo(new SolrRequestInfo(req, rsp))` to designate
that request as the current one (see
[here](https://github.com/apache/solr/blob/9ad70743a218665254f8aff15952ab4859e65b75/solr/core/src/java/org/apache/solr/client/solrj/embedded/EmbeddedSolrServer.java#L224)).
The `getUserPrincipal` method that I'm changing here belongs to an anonymous
inner class that extends `SolrQueryRequestBase`. At the time this
`getUserPrincipal` method is actually called, `SolrRequestInfo.getRequestInfo`
would return a `SolrRequestInfo` containing the same `SolrQueryRequest`
instance that this `getUserPrincipal` method is being called on in the first
place.
Another way to say this is that when we try to call
`SolrRequestInfo#getUserPrincipal` in this scenario, we don't interact with
original or enclosing request that included the original user query and the
auth info. Instead, we interact with the new request that is being created as
part of the subquery execution process.
I haven't noticed a way around this but am certainly eager for suggestions.
