Reading a file in an smbfs-mounted directory with "tail -f" or a custom test application that just uses fopen(filename, "r"), the file should show as being opened in "Read" mode on the file server (Computer Management->System Tools- >Shared Folders->Open Files). Instead (Windows 2000 SP4 in this case) shows the file is opened in "Write+Read" mode. The clent in this test case is Fedora Core 2 and samba/smbmount Version 3.0.7- 2.FC2.

This bug is *not* a duplicate of 1902. <sigh> Bug 1902 has to do with files being left-open on the file server even when closed on the client.
