[Samba] Windows 7 to Samba 4.1.4 in complete copies from CD/DVD

Wed Feb 19 14:32:32 MST 2014

I have a test server setup with Samba 4.1.4.   All file interactions test
work except when copying files from a CD or DVD to the samba share on
Windows 7.

I have a CD with a folder that contains 324 files and 22 sub-folders.
Consistently if I drag/drop or copy/paste the folder in Windows Explorer
directly from the CD to the samba share only 53 files and 4 folders get
copied.  No error dialogs appear in Windows.  Sometimes the copy dialog
appears other times it does not.

If copy the same folder from the CD to the local machine all files/folders
copy.   If I copy again from the local machine to the samba share, again
all files/folders copy.

I've increase logging verbosity to 6 and it appears Windows is only trying
the small subset of files/folders.   There are entries of looking up each
file that is missing, but never copying them

Here is the relevant log entries for some files and a directory that did
not copy:

The only error I see in the logs is:

If I launch a Samba 3.6.20 with the same smb.conf it works as expected.
I'm not sure if this is bug or a config change I need to make for Samba
4.

This is running on OmniOS with Samba 4.1.4 compiled from source.

The smb.conf is:
