Configuring AAA for network users 577

External Captive Portal

You can redirect Web portal authentication to a Web server on a network rather than a local WSS database or
RADIUS. It has the following features:
You can connect to the local WSS with Web portal enabled.
The WSS redirects you through http or https to an external authentication Web server.
Once your credentials are verified, the external server sends a Change of Attribute (CoA) to the WSS.
The CoA requests a change in the session username on the WSS.
The Web server can also change or set any other allowed CoAs at the same time.

Displaying session information for Web portal Web-based AAA users

To display user session information for Web Portal Web-based AAA users, use the following command:

show sessions network [user user-wildcard | mac-ad dr mac-addr-wildcard | ssid

ssid-name | vlan vlan-wildcard | s e ssion-id session-id | wired] [verbose]

You can determine whether a Web Portal Web-based AAA user has completed the authentication and authori-
zation process, based on the username displayed in the session table. The following command shows the
sessions for SSID mycorp.

WSS# show sessions network ssid mycorp

User Sess IP or MAC VLAN Port/
Name ID Address Name Radio
------------------------------ ---- ----------------- --------------- -----
alice 4* 192.168.12.101 corpvlan 3/1
web-portal-mycorp 5 192.168.12.102 corpvlan 3/1
2 sessions total
This example shows two sessions. The session for alice has the user’s name and is flagged with an asterisk ( *
). The asterisk indicates that the user has completed authentication and authorization. The session for
web-portal-mycorp indicates that a Web-based AAA user is on the network but is still being authenticated. The
user alice has all the access privileges configured for the user, whereas the user who is still on the portal
session with the name web-portal-mycorp has limited access to resources. By default, this user can send and
receive DHCP traffic only. Everything else is captured by the web portal.
After authentication and authorization are complete, the web-portal-mycorp username is replaced with the
username entered by the Web-based AAA user during login. The following example shows session informa-
tion for the same user, but after the user is authorized to access resources on the network:

WSS# show sessions network ssid mycorp

User Sess IP or MAC VLAN Port/
Name ID Address Name Radio
------------------------------ ---- ----------------- --------------- -----
