Well, sadly, that may not be the whole story. As a temporary fix, I just
put some code into "smb_acl_to_posix" to check for duplicate USER_OBJs,
and skip adding them to the ACL when it finds any. Windows gives me the
same error, when I try to set an ACL.
Interestingly (to me), "smb_acl_to_posix" seems to be called twice, when
attempting to set an ACL. The first time it's called, I get this ACL:
which passes the "acl_valid" check. The second time through, I get this:
which fails the "acl_valid" check. To me, that ACL looks fine (though I
do find it odd that Samba removed my group permissions, when I was adding
access for a user), but as I've said before, I'm no expert on ACLs.
Should I add this to my bug report, or create a new bug report, or is
this an unrelated issue?
