> AuthManager::Init() is not idempotent. This generally isn't a problem since 
> we call it only once per daemon, however, if we want to test with different 
> security configurations as a part of the BE tests, this causes unnecessary 
> failures.
> This is because we use a global variable to track the completion of the 
> kerberos environment setup which shouldn't be the case since we would want to 
> re-setup the environment if we call AuthManager::Init() with a different 
> configuration.
