Description Felix Botner

2014-06-17 13:19:24 CEST

+++ This bug was initially created as a clone of Bug #33785 +++

Samba 3.6 and earlier allowed open for execution when execute permissions are not present on a file. This has been fixed in Samba 4.0. This change caused an issue e.g. on Ticket#: 2013072221002032.

Starting with Samba 4.0.10 there is a new share option "acl allow execute always", which instructs smbd to skip the execute bit from the ACL check, re-establishing the old behaviour in this case.

Maybe we should make this configurable per share.

Added samba/acl/allow/execute/always (default yes) to univention-samba4 to configure samba option "acl allow execute always" (global).

YAML: 2014-06-17-univention-samba4.yaml

Verified:
 * UCR variable is documented and set on update
 * smb.conf template default is yes
 * A user logged on to a windows client can execute files without x-bit
 * setting the variable to no restores the old behaviour
 * Advisory ok
