Re: How to configure Cisco ACS 4 to work with Microsoft ISA 2004
Should all be possible. Inside the ACS help docs you need to look for
"Max Sessions" to control how many concurrent sessions a user may have.
"Quotas" are also available to limit the number of sessions during any period.
There also time-of-day/day-of-week restrictions too.
These are advanced features configured in group setup - however you will need to enable them under interface config first.
Max session/quota's require that RADIUS accounting is enabled. There are a whole load of caveats with max sessions that revolve around the NAS-Port attribute.
Basically ACS tracks session by NAS-IP & NAS-Port - if the RADIUS client doesnt include these in every packet ACS can struggle to track the sessions correctly. The RADIUS client should also support the Class attribute (ie echo the Class from the access-accept back in all accounting packets)
Provided ISA 2004 can do that you should be fine.
If you run CSRadius -z -p from the command line you'll get an attr-by-attr dump of inbound & outbound packets which is very useful.
