According to testparm, this line (force unknown acl user = yes) has no affect on the configuration. Testparm always returns force unknown acl user = 00 Is this config option only for Samba 3.0? (I have 2.2.8a). I'm wondering because it sounds like it fixes a problem I'm having: (from man 5 smb.conf) Try using this parameter when XCOPY /O gives an ACCESS_DENIED error. But it doesn't seem to have an affect. I can set (force unknown acl user = 01) and change what testparm reports, but it doesn't seem to do anything. -Tom
