Jan Høydahl commented on SOLR-12526:
------------------------------------
Ok, the reason seems to be that your auth plugin implements
{{HttpClientBuilderPlugin}}, and that effectively disables
{{PKIAuthenticationPlugin}}, see [GitHub
link|https://github.com/apache/lucene-solr/blob/1d85cd783863f75cea133fb9c452302214165a4d/solr/core/src/java/org/apache/solr/security/PKIAuthenticationPlugin.java#L287].
So in your HttpHeaderClientInterceptor#process you can delegate to PKI plugin
if it is an internal request, using e.g.:
{code:java}
coreContainer.getPkiAuthenticationPlugin().setHeader(request);
{code}
I'll close this as not a bug.
