Whenever I try to add or remove a user for access to a file I get the following error: "Unable to save permission change on <filename>. Access is denied". I took a look at my smbd log file and found this: [2002/08/29 10:40:00, 5] smbd/posix_acls.c:unpack_nt_owners(433) unpack_nt_owners: validating owner_sids.

Any ideas?
