Configuring Web Portal WebAAA 461

3The user opens a Web browser. The Web browser sends a DNS request for the IP address of the home page or a URL requested by the user.

4MSS does the following:

„Intercepts the DNS request, uses the MSS DNS proxy to obtain the URL IP address from the network DNS server, and sends the address to the user’s browser.

„Serves a login page to the WebAAA user. (Also see “Display of the Login Page” on page 461.)

5The user enters their username and password in the WebAAA login page.

6MSS authenticates the user by checking RADIUS or the switch’s local database for the username and password entered by the user. If the user information is present, MSS authorizes the user based on the authorization attributes set for the user.

MSS ignores the VLAN-Name or Tunnel-Private-Group-ID attribute associated with the user, and leaves the user in the VLAN associated with the SSID’s service profile (if wireless) or with the web-portal-wired user (if the user is on a wired authentication port).

7After authentication and authorization are complete, MSS changes the user’s session from a portal session with the name web-portal-ssidor web-portal-wiredto a WebAAA session with the user’s name. The session remains connected, but is now an identity-based session for the user instead of a portal session.

8MSS redirects the browser to the URL initially requested by the user or, if the URL VSA is configured for the user, redirects the user to the URL specified by the VSA.

9The web page for the URL to which the user is redirected appears in the user’s browser window.

Display of the Login Page

When a WebAAA client first tries to access a web page, the client’s browser sends a DNS request to obtain the IP address mapped to the domain name requested by the client’s browser. The WX proxies this DNS request to the network’s DNS server, then proxies the reply back to the client. If the DNS server has a record for the requested URL, the request is successful and the WX serves a web login page to the client. However, if the DNS request is unsuccessful, the WX displays a message informing the user of this and does not serve the login page.
