    Pluggable Remote User
    
    Select the code to handle REMOTE_USER based on a config file option
    
    Fixes the REMOTE_USER logic to get the domain name from
    REALM, which is the least surprise option.
    
    Disregards the auth_data passed in, as we should be using REMOTE_USER
    to get the user name.
    
    External Plugin is now executed in conjunction with the auth methods,
    as opposed to in place of them.
