<para>
Creating a new directory for an SMB client is a very complex task!
It includes things like inheriting permissions from the parent directory
and storing DOS attributes.
</para>
<para>
Other clients should not see the existence of the directory that
is in progress of being created!
</para>
<para>
This option is an enumerated type that controls the usage of a temporary directory name.
When this is set to <constant>yes</constant>,
the directory name will be prefixed with '.::TMPNAME:D:$SERVERID:' (where $SERVERID is
a unique identifier for the current process).
</para>
<para>
When this option is set to Auto (the default), the server uses a temporary directory name
if, at least, one of the following options
is effectively not set to <constant>no</constant>:
<smbconfoption name="inherit acls"/>,
<smbconfoption name="inherit owner"/>,
<smbconfoption name="inherit permissions"/>,
<smbconfoption name="nt acl support"/> or
<smbconfoption name="store dos attributes"/>.
</para>
<para>
A re-export of an SMB/CIFS mount might one rare case where
<command moreinfo="none">vfs mkdir use tmp name = no</command> could be useful.
</para>
<para>
In most cases <command moreinfo="none">vfs mkdir use tmp name = Auto</command> should be kept.
</para>

<value type="default">Auto</value>
