Author: araujo (ports committer) Date: Thu Oct 16 02:24:19 2014 New Revision: 273159 URL: https://svnweb.freebsd.org/changeset/base/273159 Log: Add two sysctl(8) to enable/disable NFSv4 server to check when setting user nobody and/or setting group nogroup as owner of a file or directory. Usually at the client side, if there is an username that is not in the client's passwd database, some clients will send 'nobody@<your.dns.domain>' in the wire and the NFSv4 server will treat it as an ERROR. However, if you have a valid user nobody in your passwd database, the NFSv4 server will treat it as a NFSERR_BADOWNER as its believes the client doesn't has the username mapped.
