NFSv4: Change the default setting of the nfs4_disable_idmapping parameter
Now that the use of numeric uids/gids is officially sanctioned in RFC3530bis, it is time to change the default here to 'enabled'. By doing so, we ensure that NFSv4 copies the behaviour of NFSv3 when we're using the default AUTH_SYS authentication (i.e. when the client uses the numeric uids/gids as authentication tokens), so that when new files are created, they will appear to have the correct user/group. It also fixes a number of backward compatibility issues when migrating from NFSv3 to NFSv4 on a platform where the server uses different uid/gid mappings than the client. Note also that this setting has been successfully tested against servers that do not support numeric uids/gids at several Connectathon/Bakeathon events at this point, and the fall back to using string names/groups has been shown to work well in all those test cases.
