Re: [Samba] ACL not set from Microsoft

Here's what I was looking for.

On Tue Mar 22 08:19:42 UTC 2016 Uri Simchoni posted the following to the samba-technical mailing list:

"Attached patch avoids setting the POSIX ACLs to match the NT ACLs, if "ignore system acls" is set. I believe this new behavior is more consistent with the vfs_acl_xattr man page. It also has the following benefits: - Avoid unnecessary sid->xid translations - Better compatibility with Windows, since by default Windows does not enforce existence of "traverse folder" right on parent folders, and modifying POSIX ACLs on parent folders could cause the kernel to deny access (dunno how RichACLs would handle this one :( )."

A discussion about the subject can be found on the archives after this post.

Version 4.4.3 of Samba was the first one to receive this change of behavior, as can be seen by its Release Notes:

o Uri Simchoni <uri@xxxxxxxxx>

* BUG 11806: vfs_acl_common: Avoid setting POSIX ACLs if "ignore system acls" is set.
