I am working to integrate Web Authentication with my WLC. The idea is that when anyone connects to my WLAN, before gaining access, they will be redirected to a login web auth page. After the user enters the username and password, this information will then be authenticated with my LDAP server. I have found the following link as a configuration guide, however my question/problem is: under the "security" dropdown menu, I am not seeing any LDAP selection. Is this do to the fact my WLC is running version 4.2.110?? Do I need to upgrade the WLC before I am able to authenticate with my LDAP sever? Is there something I am missing?
