Bug ID: 37103
           Summary: Wine incorrectly handles UNIX group permissions
           Product: Wine
           Version: 1.7.24
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]

Here's a very simple testcase.

You've got (userid/groupid = me) a directory which belongs to a different user
(userid/groupid = otheruser). This directory user is "otheruser". This
directory group is "me". Permissions are 770.

$ ls -la
drwxrwx---   2 otheruser  me 4096 Aug 14 00:30 TestFolder

When I'm using native UNIX applications, I can create new files and erase any
files from this folder (the sticky bit is not set).

$ cd TestFolder
$ touch testfile
$ echo $?
0

$ ls -la anotherfile
-rw-r--r-- 1 otheruser otheruser 1111 May  1 11:11 anotherfile
$ rm anotherfile
$ echo $?
0

When I'm using Wine applications, I cannNOT create new files or erase existing
files in this folder. The error is "Permission denied".
