The current CVS snapshot is now doing this. Would you happen to have any
useful examples of SDDL strings for this kind of use? Like I mentioned
earlier, I'm not really familiar with Windows security descriptors (and
don't have much interest in becoming familiar ;-). I tested this with an
empty DACL and that seemed to reject all connections, so at least the
base functionality seems to be working properly.
The format for setting SDDL string is as follows (with the silly deny
Anyway, this seems to be much better mechanism for the control interface
on Windows than UDP socket, so I will likely change the example
makefiles and projects to use this and build the binary releases with
