= Including opaque data in scheduler request messages =

If the file '''client_opaque.txt''' exists in the client data directory,
it will be included in scheduler request messages as follows:
{{{
<client_opaque>
<![CDATA[
(contents of client_opaque.txt)
]]>
</client_opaque>
}}}
and will be read into the string '''SCHEDULER_REQUEST::client_opaque''' on the server,
where it can be accessed by customizable scheduler functions.

This mechanism lets you, for example, designate particular hosts as
being trusted, having some software resource installed, and so on.

This is implemented in version [24586] of the server code.
It will work with client versions 6.13.11+.
