Jan Høydahl commented on SOLR-12526:
------------------------------------
Try to place your plugin in the same package org.apache.solr.security and it
should work. I'm planning to make that method public in some other issue I'm
working on, or change the logic so that you instead can override a method in
your AuthPlugin if you want to handle inter-node requests, otherwise PKI will
handle it by default. The last way would be a more clean impl.
