EAP Authentication using Autonomous AP and ACS Server

We have configured our AP for EAP authentication. What we want to achieve is for our clients to first be asked for a username and password before they can associate with the AP. However all we see is a prompt for WEP key, then the wireless client (laptop) starts acquiring an IP Address which it doesn't finally succeed in getting from our dhcp server. Any ideas why this is so? Can I get a detailed documentation on how to configure EAP using only an Aironet Access Point and ACS Server without a WLC. Thanks in advance.

Re: EAP Authentication using Autonomous AP and ACS Server

EAP Authentication option enables 802.1X authentication (such as LEAP, PEAP, EAP-TLS, EAP-FAST, EAP-TTLS, EAP-GTC, EAP-SIM, and other 802.1X/EAP based products) This setting uses mandatory encryption, WEP, open authentication + EAP, network EAP authentication, no key management, RADIUS server authentication port 1645. You are required to enter the IP address and shared secret for an authentication server on your network (server authentication port 1645). Because 802.1X authentication provides dynamic encryption keys, you do not need to enter a WEP key.

For the configuration for the EAP following guide may help you :
