/*
 * The Security QuickStart Example.
 *
 * This example takes the following steps:
 *
 * 1. Sets the authinit property and the other security properties.
 * 2. Connect to a Geode Distributed System.
 * 3. Does all operations. ( for which it has all permissions)
 * 4. Does a put and get. ( for which it have put permission. )
 * 5. Does a get and put. ( for which it have get permission. )
 * 5. Close the Cache with keepalive options as true.
 * 6. Disconnect from the Distributed System.
