RFC-3530, which has not yet been replaced as the RFC for NFSv4.0 does not recommend this. A requirement for client support of this is in an internet draft called rfc3530bis, but this has not become an RFC yet. I think the Linux folks "jumped the gun" when they made this the default. You can change this using a sysctl on the server, so that it uses the <username>@<domain> format recommended by RFC-3530 or you can upgrade to stable/9, which does have client support for the uid in a string. (The "uid in a string" was added mainly to support NFSv4 root mounts for diskless clients.) This PR will be closed when I get home next week and can do so. rick > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
