On my linux box I can see acls on a windows share using smbcalcs. Invoking as: "smbcacls <share_name> <file_name>" I get output that contains a number of lines that look like: "ACL:BUILTIN\Administrators:ALLOWED/I/FULL". So far so good. However I have yet to find an invocation of smbmount that allows me to mount the same share and then see the acls with getfacl. Is it possible to do this?
