Package: cifs-utils
Version: 2:6.8-2
Severity: normal

Dear Maintainer,

on a remote samba server we have set up some permissions using windows ACLs.
Shares on clients are mounted with multiuser,cifsacl via autofs.
(fstype=cifs,rw,multiuser,cifsacl,username=cifsmount,soft,sec=krb5i,vers=3.0)

When copying a file to a share the permissions set on the folder on the server
are not inherited by the copied files.
However, when creating files directly on the share the permissions are
inherited.

Workaround: The permissions are set up on copy as anticipated when not using
the mount option cifsacl.

PLease fix this.
If you need any more information feel free to ask.

Best regards
Jens
