We are a sort of service provider network for schools, and use a Cisco ACS and its internal user database to authenticate users onto the remote access VPN which we provide. Every school we support has a separate Windows domain.
We would like to be able to use the ACS to connect to the different school ADs to be able to allow them to authenticate using their local network credentials.
Can this be done, and if so is there a specific software version of the Cisco ACS that is required? We are currently running 3.3 and I don't seem to be able to find a way of making this work.
