Um, yes, that's entirely what I meant. EXTERNAL doesn't work at all over
TCP, AFAIK (the only implementation is SO_PASS_CRED on Unix sockets,
which clearly doesn't work on either TCP or Windows), I don't know why
it is trying that.

I don't know either, neither do I know of any way to access this from
Java. I see no reason not to use a file as with the Unix TCP solution.
This would work with shared SMB directories as with shared NFS home
directories (maybe).
