An updated secure library mode quickstart should be created which demonstrates node security using callbackhandlers for authenticating new entrants to a jgroups cluster.

There should be a quickstart that demonstrates callbackhandler usage, while enabling inter-node authentication in library mode. I have a working build, and am working to migrate this work into a quickstart, such as "secure-embedded-cache" or a uniquely named similar quickstart. (This is a duplicate of ISPN-7037 since the actual quick-starts being referenced exist under JDG's quickstarts on github.)
