smb.conf used on a slackware 64 server

File in Root directory can not be deleted using the MS DOS Client 3.0. 

For example:

Typing on the DOS Console
mkdir ADIR             ENTER KEY
CD ADIR                ENTER KEY
copy con A             ENTER KEY
Some garbage Text^Z    F6 KEY Followed by ENTER KEY

del *.*                ENTER KEY
This is followed by Are you sure (Y/N)?y

Pressing Y and enter is then followed by 
File not Found

del A

works fine.

I tested this on a slackware 64 bit as well as a 32 bit.

Repeating the same operations using a windows 7 client on a mapped drive work.

Please upload wireshark trace and debug level 10 log between client and server.

Thanks !

Wire Shark Capture

I mounted \\server\drived

created a file with copy con A

tried deleting it with del *.*

Finally deleted it using del A

OK, I think I've spotted the bug. Missing map of dtype from zero -> FILE_ATTRIBUTE_NORMAL in the wildcard delete case.

Patch to follow.

Fixed patch for mater (fixes samba3.raw.unlink error).

Ah - fails on source4/torture/raw/unlink.c,
but that test code is incorrect anyway (it adds
a special return check for NT_STATUS_NO_SUCH_FILE
if the server is Samba3 - Samba should return
NT_STATUS_OK here as Windows does).

That's kind of funny - as it means we already
had a proper test for this but instead of
noticing and fixing the bug in the server,
we hacked in a "if Samba3" workaround for
our incorrect response :-) :-).

Updated patch attached. Andreas if you
could just review the samba3.raw.unlink
fixup (last hunk of the patch) it's
good to go !

Cheers (and sorry about the error),
