Wireless newbie here and hopefully someone can help me answer this.
Currently, we use Cisco wireless 1130 AP with EAP-FAST to Cisco ACS 3.2 with username and password authentication. All is working well. We have another Cisco ACS 4.2 on a separate server and want to move the wireless 1130 AP to use the new Cisco ACS 4.2. All settings and profiles have been migrated over to the new ACS 4.2. If we change the RADIUS setting on the wireless 1130 AP to point to the new Cisco ACS 4.2, will the user authenticate automatically or will there be some type of manual intervention by the user? The environment has hundreds of laptop users. So anyone with gotchas or has gone through this, can you please share your experiences?
