INN Scalability

[Forrest Aldrich]

It's been a number of years since I've used INN, so it's been fairly 
interesting catching up with all the changes and the myriad of 
configuration files.

I'm looking for some information about scaling INN to Enterprise 
levels.  One obvious question is how to provide authentication for a 
large userbase (1,000 - 100,000 users).   Plain text won't work :-)   
Radius might...  anyone else have anything to add to that equation.

I was surprised that even O'Reilly doesn't appear to have an updated 
"Managing Usenet" book - I actually have a copy, and found that it's 
really dated (in a lot of ways), so am left to peruse the Internet for 
reference material.   Anyone know of other published guides, etc.


Thanks.
