This is also broken with a FreeBSD-current client and server. The problem seems to be that nfsrv_access() pretends that the permissions are 777 for the owner of the file. nfsV2 clients apparently understand this, but nfsrv_access() is used internally by V3 parts of the server, and the server doesn't understand itself. This seems to be fixed in NetBSD by passing an `override' arg to nfsrv_access() to tell it when to fudge the permissions. Bruce
