Need help

[David J. Orman]

Hi,

  Working on a project that is going to require some pretty nifty 
setups. I'm not too familiar with things on this scale so I need some 
input, if at all possible.

I'm looking at setting up thousands of accounts, across multiple 
servers. Most will require: email and webhosting. Some database 
accounts, but not nearly as many as email/hosting.

Well, I need a solution that would allow me to create users in some 
centralized location, and have the servers access that. It would start 
off as just two servers, one for mail one for web, and then maybe 
another server for whatever method the user accounts are stored/used.

So, pretty much, virtual accounts on the servers for both mail/web. I 
really don't know how to go about this, any suggestions would be 
welcomed! I looked at CPanel and H-Sphere and DirectAdmin and etc, but 
it's not for me. 

Cheers,
David
