  - attemptAuthentication
```
java.util.Collection<? extends GrantedAuthority> attemptAuthentication(java.lang.String username,
                                                                       java.lang.String password)
                                                                throws RemoteAuthenticationException
```
    Attempts to authenticate the remote client using the presented username and password. If authentication is successful, a collection of GrantedAuthority objects will be returned.
    In order to maximise remoting protocol compatibility, a design decision was taken to operate with minimal arguments and return only the minimal amount of information required for remote clients to enable/disable relevant user interface commands etc. There is nothing preventing users from implementing their own equivalent package that works with more complex object types.
    
    Parameters:
    
    username - the username the remote client wishes to authenticate with.
    
    password - the password the remote client wishes to authenticate with.
    
    Returns:
    
    all of the granted authorities the specified username and password have access to.
    
    Throws:
    
    RemoteAuthenticationException - if the authentication failed.
