Description Walter Laub 2012-08-23 11:55:31 UTC 
samba 3.5.17 on AIX 5.3

Scenario: try to delete a file without permissions, will give no warning or message and ERRORLEVEL is zero:

DEL [SHARE]\test.txt
IF ERRORLEVEL 1 ECHO Error

(the file is not deleted)
Comment 1 Jeremy Allison 2012-08-23 16:55:36 UTC 
Debug level 10 log from smbd please. We should be returning a NT_STATUS_ACCESS_DENIED on file open. If we return it on close (when we actually are requested to do the delete - as to delete a file the client requests and open with "delete-on-close" set and then closes the file - then the client ignores the error on the close :-(. ). Windows is very sad :-(.

Jeremy.

samba.log, log level = 10

In the log file you will find 2 delete from Windows Explorer (GUI) and 1 from cmd.
No message or errorlevel > 0 (cmd) is returned.

is this still an issue with recent samba 4 versions?
Comment 4 Walter Laub 2018-03-28 08:24:53 UTC 
Oh, an old issue :-)

I tested again, now on Linux, no AIX with samba 4 available:
smbd -V
Version 4.6.3-git.25.0c154becb132.1-SUSE-oS13.1-x86_64

Client is Winodws 10, 1709:
del [SMB-SHARE-Folder]\test.txt
[SMB-SHARE-Folder]\test.txt
Zugriff verweigert ("Access denied")

But ERRORLEVEL is still 0. Not sure, but possible, this is client (Windows) related?
Comment 5 Björn Jacke 2018-03-28 08:46:15 UTC 
well, looks like windows relates, "del thisfiledoesnotexist" even results in ERRORLEVEL 0 on local storage. Closing this bug accrdingly now.
