* This realm populates a number of special login module options for the

* JaasLoginModuleUse.KERNEL_LM_OPTION String (Kernel name) Yes
* JaasLoginModuleUse.SERVERINFO_LM_OPTION ServerInfo No
* JaasLoginModuleUse.CLASSLOADER_LM_OPTION ClassLoader No

* These options can be safely ignored by login modules that don't need them
* (such as any custom LoginModules you may already have lying around).
