Cifs connection failure, Cifs delete on close denial, Cifs file access denied – Dell PowerVault NX3600 User Manual
Page 73: Cifs file sharing conflict

CIFS Connection Failure
Description
CIFS client share access denied.
Cause
The user is unknown in the Active Directory server, and
the NAS system mapped this user to a guest user. If the
share does not allow guest access, the user receives an
access denied alert.
Workaround
Ensure that the user is listed in the Active Directory server
the NAS is using. Alternatively, you can remove the guest
limitation for the share. If the user can now access the
share as guest, the newly created files are owned by the
nobody/guest user.
CIFS Delete On Close Denial
Description
Files are deleted while they are in use.
Cause
If a file is deleted when it is open, it is marked for deletion,
and is deleted after it is closed. Until then, the file appears
in its original location but the system denies any attempt
to open it.
Workaround
Notify the user who tried to open the file that the file has
been deleted.
CIFS File Access Denied
Description
CIFS file access denied.
Cause
Client has insufficient privileges to perform the requested
operation on the file.
Workaround
This is an informative event. The user may request to
modify the file ACL to allow access.
CIFS File Sharing Conflict
Description
CIFS file sharing conflict.
Cause
When a file is opened using the CIFS protocol, the opening
application communicates the sharing mode that must be
used while this file is open.
This sharing mode describes what other users' activities
are allowed on this file, while it is open.
This definition is sent by the application and the user
cannot control/configure it.
Once there is a violation of the sharing definition, the user
receives an access denied error and this event is issued.
Workaround
This is an informative event, the admin may contact the
locking user and request to close the application
referencing this file.
