A user is attempting to use Windows Powershell get-childitem command to
copy files from one SMB directory to another.

*****************
Get-ChildItem -Path "W:\z_TestFiles\source1" -Recurse -File |
ForEach-Object {
    Copy-Item -Path $_.FullName -Destination "X:\dest1"
}
*****************

When the command is run it creates the files as 0 byte files and then
errors.

*****************
Copy-Item : Element not found.
At line:2 char:5
+     Copy-Item -Path $_.FullName -Destination "X:\dest1 ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Copy-Item], IOException
    + FullyQualifiedErrorId :
System.IO.IOException,Microsoft.PowerShell.Commands.CopyItemCommand
*****************

When I look at the zero byte files in Unix
drwxrwxr-x   2 ourapp    digicol        6 Mar  1 14:02 .
drwxrwx---   8 user digicol       11 Mar  1 14:02 ..
-rwxrw-r--   1 ourapp    digicol        0 Mar  1 14:03 2022-02-15

When I set the owner of the directory to the user.  This works fine.
drwxrwxr-x   2 user    digicol        6 Mar  1 14:02 .
drwxrwx---   8 user digicol       11 Mar  1 14:02 ..
-rwxrw-r--   1 user    digicol  14321 Mar  1 14:03 2022-02-15

Cutting and pasting using Windows Explorer and Teracopy, usually but not
every time, works properly.    I haven't figured out what causes this to
work sometimes and not others.

>From what I have seen the problem is the inheriting of the owner, which is
necessary for our application and outside of my control.

In our smb.conf file
[global]
   allow insecure wide links = yes
   unix extensions = no
   log level = 1
   load printers = no
   printing = bsd
   printcap name = /dev/null
   disable spoolss = yes
   min protocol = SMB2
   workgroup = MYGROUP
   server role = standalone server

[application]
        path = /application
        comment = Application Shared Folder
        follow symlinks = yes
        wide links = yes
        writable = yes
        inherit permissions = yes
        inherit owner = yes
        inherit acls = yes
        valid users = @application


Solaris 11.4
Samba 4.13.17

In advice on what I need to look at to make this behave properly.

Thank You in advance.
