Created attachment 26648 [details] I made a patch. When Tomcat registers an authenticated Principal and authentication Type with current session, only authenticated Principal is replicated, and authentication Type is not replicated. Therefore, Request#getAuthType() returns null though the request is authenticated when the node changed. Best Regards.
Fixed in 7.0.x and will be in 7.0.9 onwards. Proposed for 6.0.x and 5.5.x
