Hmm, hadn't tried that, but flipped it on to see how it might work out.
The only tradeoff is a potential delay between when an account is
disabled and when it can stop authenticating. I set the timeout to 10
minutes for now, with an hour timeout for negative caching.

That page says you can send a USR2 signal to the auth process for cache
stats? That doesn't seem to work. OTOH, that page is for version 1, not
2; is there some other way to generate cache stats in version 2?

Thanks...
