Pivotal GemFire 9.0 or later
Pivotal GemFire 7.0.2.x and 8.x provided sample codes and security modules in the SampleCode and templates directories (or, as compiled modules, in lib/gfSecurityImpl.jar). Where are equivalent sample code and security modules for Pivotal GemFire 9.0 or later?
You can find the ode for sample security modules on GitHub (linked below). Note, however, that these are totally different from the Pivotal GemFire 7.0.2.x and 8.x's modules because the underlying security implementations have been changed in Pivotal GemFire 9.0.
The compiled security modules are included in lib/geode-core-*.jar.
