[Samba] Windows C# unable to access Samba directories.

[PC]

We have written a program which queries Windows mounted drives (including
Samba mounts) for files and directories.

 

The program cannot find folders which are not owned by the user who spawned
the application.  The user belongs to the group (owner - group - others)
with rw permissions and can locate all files and folders via Windows
Explorer.

 

It appears that Samba is unable to resolve the group permission for some
windows applications.

 

A similar problem can also be demonstrated when using Windows Offline files
/ folder capability on a Samba mounted drive.  Synchronizing offline file
will fail unless all files and folders are owned by  the user who spawned
the application.

 

Any clues?
