This will be used to in order to pass down the impersonation magic from the SMB layer through the SMB_VFS layer. This includes the following options: smbd:force sync user path safe threadpool smbd:force sync user chdir safe threadpool smbd:force sync root path safe threadpool smbd:force sync root chdir safe threadpool They can be used in order to test the non linux code path on linux, once we get code that makes full use of the new infrastructure.

/*
|
|
This module performs a read-only limitation for specified share
|
|
(or all of them if it is loaded in a [global] section) based on period
|
|
definition in smb.conf. You can stack this module multiple times under
|
|
different names to get multiple limit intervals.
|
|
|
|
The module uses get_date() function from coreutils' date utility to parse
|
|
specified dates according to date(1) rules. Look into info page for date(1)
|
|
to understand the syntax.
|
|
|
|
The module accepts one parameter:
|
|
|
|
readonly: period = "begin date","end date"
|
|
|
|
where "begin date" and "end date" are mandatory and should comply with date(1)
|
|
syntax for date strings.
|
|
|
|
Example:
|
|
|
|
readonly: period = "today 14:00","today 15:00"
|
|
|
|
Default:
|
|
|
|
readonly: period = "today 0:0:0","tomorrow 0:0:0"
|
|
|
|
The default covers whole day thus making the share readonly
|
