A second-level cache next to SHM would require the data to be dumped on 
and read from disk at start time. I'm not sure what the security 
implications of that would be.

Anyway, what are you trying achieve? Are you seeing performance issues 
with user authentication when restarting? The fact that is option is 
(AFAIK) not available indicates that this isn't a problem for other 

With kind regards,
