One-Time authentificaton for multiple servers

Hello,

I have a couple of servers (currently 42 Web-Servers et a redunant
PostgreSQL for AUTH) and I am trying to get a One-Time authentification
running.

Exactly:

It should not mather on which Web-Server the $USER authenticate and if
she/he change the website dynamicly...  The AUTH should be done on the
PostgreSQL and then the Web-Server should ask the PostgreSQL whether
the AUTH is valid or not.

I need a variable timeout (per $USER) and it should be refreshed each
time the user klick a link or such...  After the timeout, the $USER need
to re-authenticate again on one of the Web-Servers.

In general, I prefer to use PAM auth because the infrastructure is there
and more easier on Debian-Systems.

Can anyone tell me how to do this?

Note:  I will have over 700.000 $USER if the whole thing is running and 
       we will use at least 200 Web-Servers and 8 PostgreSQL world wide.

Thanks, Greetings and nice Day
