topic ACS Authentication in Network Access Control https://community.cisco.com/t5/network-access-control/acs-authentication/m-p/436599#M428898 <P>We have ACS up and running with no problems. We have a special VLAN for a public kiosk that customers can use to surf the internet. The kiosk is wireless and is configured to auto-login with a specific account. The access-point is using vlan 1 and vlan 40 for the wireless kiosk. When the kiosk machine authenticates to ACS running on our domain controller (which resides on vlan 10) - is the kiosk machine communicating with the domain controller or is the kiosk machine communicating with the access-point, which in turns communicates with the ACS server? I would like to block vlan 40 from accessing vlan 10 but if the kiosk machine needs to communicate with the domain controller I don't think I can. Any help is appreciated. Thanks.</P> Sun, 10 Mar 2019 21:12:45 GMT unionbancorpit 2019-03-10T21:12:45Z ACS Authentication https://community.cisco.com/t5/network-access-control/acs-authentication/m-p/436599#M428898 <P>We have ACS up and running with no problems.

The AP will forward the credentials onto the ACS server which in turn will try to authenticate them to the Windows DC. </P></BODY></HTML> Tue, 05 Jul 2005 22:24:06 GMT https://community.cisco.com/t5/network-access-control/acs-authentication/m-p/436600#M428900 gfullage 2005-07-05T22:24:06Z Re: ACS Authentication https://community.cisco.com/t5/network-access-control/acs-authentication/m-p/436601#M428902 <HTML><HEAD></HEAD><BODY><P>Thanks for the information.</P></BODY></HTML> Thu, 07 Jul 2005 13:16:45 GMT https://community.cisco.com/t5/network-access-control/acs-authentication/m-p/436601#M428902 unionbancorpit 2005-07-07T13:16:45Z
