5760 Central Web Auth with ISE

Hi,
I am having problems with getting central web auth to work on the 5760, I cant seem to find any documentation for the 5760-Central Web Auth.
The setup is with a Cisco 5760 and Cisco ISE, for guest users to be re-directed to ISE guest portal to authenticate. Has anyone configured this or have any advice, that would be great.
Thanks

Hi Roger,
I have gotten CWA running on the 5760 with ISE, below is the config for the guest SSID:
wlan Guest 1 TEST-guest
aaa-override
ip dhcp required
mac-filtering cwa_macfilter
mobility anchor 10.1.1.100
nac
no security wpa
no security wpa akm dot1x
no security wpa wpa2
no security wpa wpa2 ciphers aes
security dot1x authentication-list ISE_Auth_Group
session-timeout 14400
no shutdown
! ***You will need the following commands as well:
ip http server
ip http authentication local
ip http secure-server
aaa authentication login ISE_Auth_Group group ISE
aaa authorization network cwa_macfilter group ISE
Hope it helps =)

Central Web Auth with Anchor Controller and ISE

Hi All
I have a 5508 WLC on the corporate LAN and another 5508 sat in a DMZ as an anchor controller.
I also have an ISE sat on the corporate LAN.
Authenticate is working fine to the ISE and the client tries to re-direct to the ISE Portal but doesn't get there.
DNS is working fine and the client can resolve the URL of the ISE to the correct IP address.
I have a redirect ACL configured on the foreign controller which permits DNS, DHCP and traffic to and from the ISE.
My questions are:
1. Do I need to re-direct ACL to be present on both the foreign and anchor controllers?
2. Since the Radius requests originate from the foreign controller do I need to configure the ISE server address on the WLAN on the anchor?
3. Does the re-direct ACL need to be enabled on the advanced page of the WLAN on the foreign to over-ride the interface ACL - I don't believe it does.
4. Is ICMP still blocked by the WLC until the web authentication is complete?
Thanks.
Regards
Roger

Hi Roger,
Thanks for your brief explanation here are the answers for your queries.
1. Do I need to re-direct ACL to be present on both the foreign and anchor controllers?
The only catch is that since this web authentication method is Layer 2, you have to be aware that it will be the foreign WLC that does all of the RADIUS work. Only the foreign WLC contacts the ISE, and the redirection ACL must be present also on the foreign WLC.
2. Since the Radius requests originate from the foreign controller do I need to configure the ISE server address on the WLAN on the anchor?
Yes, you have to configure the ISE server address on the anchor WLC.
3. Does the re-direct ACL need to be enabled on the advanced page of the WLAN on the foreign to over-ride the interface ACL
Yes, you should override AAA under advanced tab of WLAN as ACL will be present on the foreign WLC.
4. Yes, ICMP will work only after the sucessful web auth is complete.
Please do go through the link below to understand the Anchor-Foreigh Scenario.

Web auth with , intenal web page of WLC and ISE as radius server

Hi All ,
We have created a SSID as web auth with internal web page for login . In advanced tab we configured AAA server. AD is integrated with ISE .
When the user tries to get connect , he is getting redirect URL . But during the authentication , we are getting error in ISE as
"ise has problems communicating with active directory using its machine credentials " and authentication getting failed .
When we have L2 security mechanism enabled with PEAP , ISE is able to read the AD and providing authentication .
Only for L3 web auth it is not happening..
Any clue on this ..???
Thanks,
Regards,
Vijay.

Machine credentials requires a lookup on the computer OU and that has to be defined on the client side.

Not Working-central web-authentication with a switch and Identity Service Engine

on the followup the document "Configuration example : central web-authentication with a switch and Identity Service Engine" by Nicolas Darchis, since the redirection on the switch is not working, i'm asking for your help...

WLC 7.5 Sleeping clients with ISE and Central WEB Auth(CWA)

Hi there,
Is it possibe to use sleeping clients when using ISE and CWA?
I was thinking of enabling layer3 auth with web auth on mac auth failure, but will that work with CWA?
Or is the only solution to use LWA?

Controller-> General-> User Idle Timeout (seconds) = 50 000 sec.
And your users will be connected all this time even if they going in sleepmode

Guest Anchor with web auth using ISE guest portal

Hello All,
Before launching into my exact issues, could anyone confirm if they have completed a wireless Guest anchor setup using 2504 controllers on 7.4 as the anchor (5508 is the foreign) with webauth external redirection at ISE 1.1.3 using ISE Guest Services?
I am attempting this for an internal POC and have hit a couple of issues. Firstly I am looking for correct configuration confirmation prior to going in depth with a couple of the issues. I've been using the TrustSec 2.1 how to guides to build the parts I am not strong on so if anyone has actual completed this setup, I'd love to go through it with you.
massive thanks to anyone that can assist.
JS.

Thanks for the reply RikJonAtk.
so to start with, based on the trust sec documents, of the guest WLAN on the anchor I need to configure mac filtering at the layer 2 security menu as well as enable RADIUS NAC under the Advanced tab. But when I do this, I get an error message that states that mac filitering and RADIUS NAC cannot be enable at the same time.
Additionally, if I just enable the RADIUS NAC setting under the Advanced tab in the WLAN, I get another error message that states that the priority order for Web-Auth can only be set for radius, so I go to the AAA server tab and send local and LDAP to the not use column and hit apply. If I move to another menu then check the priority order again under the AAA servers tab, the local and LDAP have been moved back to the menu field to be used again. So I initially though it might be a bug, but I was hoping to find someone here that has done this already and can look at my issues and maybe walk me through their configs, which I'll mirror and see how it goes.
Thanks in Advanced,
JS

Web-Auth with 802.1x

Environment is WLC 2106 with 4 LWAPP access points. Currently running 2 WLANs: 1 using 802.1x authentication with a Windows IAS (RADIUS) server for Active Directory authentication; 1 using basic WEP for guest access that drops the user in it's own secure VLAN.
I am trying create a 3rd WLAN that uses Web-Authentication using 802.1x RADIUS that passes the username/password to the Windows IAS server. I can see the request being passed to the IAS server, but it is being logged on the IAS server as:
An Access-Request message was received from RADIUS client WLAN Controller without a message authenticator attribute when a messages authenticator attribute is required. Verify the configuration of the RADIUS client in the Internet Authentication Service snap-in (the "Client must always send the message authenticator attribute in the request" checkbox) and the configuration of the network access server.
I already have the one WLAN using 802.1x where the RADIUS client on the IAS server has the "Request must contain the Message Authenticator attribute" checkbox checked and it works jsut fine. It is just the Web-Auth using 802.1x where it seem the authentication isn't being passed properly to the RADIUS server. I cannot figure out what I am doing wrong or missing.

Hi,
I don't know if you have resolved the problem or not, But I will propose my solution anyway,
There are two ways to solve this problem, either to make the controller send the radius request with md5 or make the windows reply to the radius requests that does not contain a md5 hash
Microsoft Solution:
When you add the Radius Client using the wizard there are certain options that don't show; for instance the md5 attribute that is causing the IAS to drop the web auth requests. So what you need to do is after you use the wizard, you right click on the client that you added (in our case the WLC) and uncheck the box that says "Access-Request message must contain the Message-Authenticator attribute" (attached is a screenshot).
That should make the IAS respond to the web auth requests.
WLC Solution:
I haven't tested this solution, but I think it will work. if you did test it, please let me know how it turned out.
By default, the Web Radius Authentication is set to "PAP" (can be found in the Controller Tab @ the WLC GUI), you need to set it to MD5-CHAP. (attached is another screenshot).
Hope that solves your problem, and please let me know how the problem was solved.

How to generate CSR on switches for web auth with NGS

Hello
I am doing a dot1x solution with web auth on cisco 3750 switches.
Once the wired client get put into web auth state (after dot1x and mab) and goes to a website, he gets a certificate warning. This is because the certificate of the cisco switch is selfsigned.
I want to use a verisign certificate to solve this error, but I cannot find a way to generate a CSR on a switch. I only found a guide how to request a certificate from a CA on the local network, but this is also not a solution, because the clients using the web auth, will not know the internal CA.
Is there any way to solve this?
Greetings
Steven

Hi Steven,
The below document is actually for IOS SSLVPN, but the certificate portion should be the same:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6657/white_paper_c07-372106_ps6657_Products_White_Paper.html
Search for "Appendix B" and it goes into creating a trustpoint and then one section is for self-signed and another is for generating a certificate request to send to an external CA.
Once a trustpoint is created the command to actually generate the CSR is "crypto pki enroll ".
This document goes into a little more detail on all the indivual commands and what they do:
http://www.cisco.com/en/US/docs/ios/sec_secure_connectivity/configuration/guide/sec_cert_enroll_pki.html
Also you could use something external to the switch like OpenSSL to generate the CSR/private key and then use that to request a cert from your Verisign CA and then import the cert/keypair into the IOS device.
Thanks,
Nate

Web Auth with AAA (RAIDUS) Failure

Hi Guys,
We are having an issue with out Web Auth Using AAA Servers. We get the following error: AAA Authentication Failure for UserName:14t.park User Type: WLAN USER, This error is from the Web Interface, I have been looking at the debug settings to see if there is anything that might give me more detail of what is going on but I can see anything under the Web-Auth Debug for AAA Authentication.
I have checked on our RAIDUS Servers and I can't find any errors relating to Authentication with the NPS.
Does anyone have any suggestions?

Web auth with proxy

I want the automatic redirection to the login page work when a proxy is configured in the IE parameters.
I used the command "config network web-auth-port 8080", but when I open IE, I'm not redirected to the login page (the DNS request works).
When I do a "telnet www.google.com 8080" and then "get http", I get the page.
Any idee?

In my experience it does not work with a proxy. If you disable the proxy you will get the login and then get redirected, which will then fail until you enable the proxy settings. WLC will try to resolve the homepage of that user, which of course will fail since it doesn't know of the proxy. You will have to either use a term and condition on a custom WebAuth page or implement a content filter application like WebSense.

Web Auth with Mac Filtering

I am trying to setup a scenario where a user logs in via Web Auth and witha successfull connection the Mac Address is remembered for 7 days. That way if the user connects again during the course of 7 days they aren't required to authenticate via web auth again they just get access. After 7 days they will need to login again through the web auth. Similar scenario to what you see at a Hotel wireless network. Anyone know how I would go about setting up the dyanmic mac filtering and set the timer for 7 days? With that said I want it to be for a single SSID.

well, it's not possible with just the WLC.
You can do it, but you need to have a way to pull the MAC address from the webauth page, and insert that into a LDAP db, which you control the age out process in.
Then on a subsequent visits they get mac-authed instead of having to re-accept the page.
in the webauth config you would check the On MAC filter failure box.

Steve

ISE and WLC for CWA (Central Web Auth)

Hello All,
As we know that WLC (i.e. 5508) does not support MAB (MAC Auth Bypass) and it supports CWA in 7.2.x.
CWA is a result of successfull MAB. So how CWA work for wireless? So it means WLC support MAB?

I've been playing around with this and have it working on 7.3.101 on the WLC 5508, however, I don't seem to be receiving the web redirect correctly. When I look under the client connections on the WLC I see that the URL is received on the WLC from ISE, but it appears to be truncated, unless that's just a limitation of the display. I see hits on the ACL-WEBAUTH-REDIRECT ACL on the controller, but it doesn't seem to be redirecting. I have this similar configuration on the wired side of the house and it works fine. ISE just shows pending webauth, as it should.

WLC 5508- how to setting up with Web auth with 2 profile

Hi Guys,
I wanted to control the 2 different profile to access internet with Cisco default landing page is that possible??
Example:
When connnected the SSID will redirect to Cisco landing pages
Cisco landing pages will differentiate there is member or guess with the password key in.
Member can access internet for 30 minute
guess only can access internet for 15 minute

Just some notes on WebAuth in the WLC. The timeout is specified per SSID so there would be no way to set a timeout unless you use a radius server and send a radius attribute to the WLC to set the session timeout.
So we really need to know if you have a radius server, is the radius server tied to Active Directory or is the plan just using the WLC for everything.

Radius server web authentication using ISE

Hi,
Can anyone point me in the direction of a guide to implement radius server web authentication using ISE?
I need this to be layer 3 Web Auth with all authentication requests coming from the wireless anchor controller, therefore don't think I can implement central web auth on ISE as detailed in the user guide as its layer 2 and auth requests come from the foreign controller.
The following link explains "Radius Server Web Authentication" using ACS. I need to find something similar for ISE - http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/69340-web-auth-config.html
