terminal not sending auth requests

The thing that doesn't get configured is a way to call the auth
server when the boot method is tcp.  It doesn't need the auth
server to talk to u9fs since u9fs uses ruser() to accept or
reject.  However, if you log in as anything either than 'none'
then the kernel tries to check whether your key/password works.

If you want to use u9fs as your main file system and have an auth
server you can call up via il, you could change in
/sys/src/9/boot/ip.c:

int
authtcp(void)
{
	return -1;
}

to

int
authtcp(void)
{
	return authil();
}

I'ld assumed using tcp for file service implied no auth server, i.e.,
that you were logging in as 'none' to get Plan 9 installed and would
never really run that way (u9fs isn't the worlds fastest file server
by a long shot).  Bad assumption especially not that there's a Unix
auth server.
