MAC Exception for Web Authentication

Hello folks. I currently have a guest network setup using guest tunneling and an anchor controller. I have it configured for web authentication. So basically, a client associates to the SSID, obtains an DHCP IP from the guest anchor controller, and then when the browser is launched the client is redirected to 1.1.1.1 and receives the splash page where they are required to click "OK" to proceed and begin surfing the internet.
I am being told from a vendor that it's possible to use a mac-address exception method so specific clients (based on mac address) will not have to web authenticate. So basically they bypass the splash screen and can immediately begin surfing the internet.
From what I can tell it's all or nothing per SSID.
Has anyone ever heard of this and if so do you know how it is accomplished.
Thanks
Chuck

I've seen people ask for something like this for like an XBOX in a dorm (appearently XBOX doesn't have a browser?).....
Bottom line though is that on the WLC, all wireless clients on a WebAuth/WebPassthrough SSID must pass layer3 authentication. There is no way around this on this SSID. You'd have to create a different SSID as Scott suggested, which I'd probably suggest doing some kind of PSK on it, so only a few priveledged devices can associate.... you could even through in mac-filtering if you really wanted to complicate it....
Now, I understand that switches may have such a feature called mac-bypass, but it isn't on the WLC.

Port 80 for Web authentication?

Hi,
Is it possible to use port 80 for web authentication instead of port 443?

Sure... on the later code versions you can set the WebAuth to use either http or https by disabling WebAuth SecureWeb (http) or enabling it for https.
Thanks,
Scott

Guest Parameter for Web Authentication

Hi Forum,
Just to find out a little more detail in regards to the guest account created for web authentication using Ambassador account.
1) If the authenticated guest did not perform a proper logout, what action will the WLC take?
2) As such, is there any timeout involved?
Where can i tune the timeout?
Rdgs,
Kelvin

Hi I just wanted to add what I have found regarding WCS and the guest feature.
-There are two ways to configure a "local net user". The first is a static guest ID that has the "guest" flag off. This means that the client's session will not timeout. The second is to specify the "guest" user checkbox and give it a timeout value in seconds.
This should let you control how long a user is logged in.
From the WLC login, go to SECURITY --> LOCAL NET USERS --> then click on NEW. From there you can specify a user ID and also set that optional guest user box. If you click on the Guest User box then you will see a timeout field.
With my guest account set to not be a guest user (no timeout value), I have noticed the following.
1. If a guest gets disconnected, usually they will reassociate and still be able to log in.
2. If a guest has problems, I usually tell them to disable their wireless card, close all browser windows, and then reassociate to the network.
The steps above have worked well for my setup...

Possible to use http for web authentication?

Hi All,
We are using WLC 2500 and AP 1041 with web authentication. Due to we do not have the trusted/public certificate and want to get rid of the certificate warning during the user login. I would like to ask if this is possible to change the web authentication method from HTTPS to HTTP. Thanks.
Rgds,
Jacky

Hi Jacky,
Yes u can... But there is a catch..
1) If ur running WLC code below 7.2.X then the only option is to disable HTTPS globally (Meaning HTTPS management access disabled only HTTP).
2) If you are running 7.2.X and above, then you can use HTTP for client webauth and then HTTPS for Management access.
The command for disabling https for web authetication would be:-
config network web-auth secureweb disable
Hope that helps

PSE 8 MAC save for web not working

I upgrade from PSE6, and I used to use save for web all the time. Since I upgraded to 8, when I click on save for web it does nothing, no error, just nothing. I saw in the form were a user had the same issue with 6 and I tried deleting the files and fixing permissions etc. Anyone else having this problem, or any suggestions?
thanks,
charles

I had the same issue. Running in a non-admin account I was unable to do a Save for Web. I switched to my admin account and it worked there. When I switched back to my non-admin account it now works ok. As an aside, same situation with changing the program icon for PSE 8.

WLC Virtual Interface config for a public SSL cert for Web Authentication

I'm trying to get a cert loaded on my 5508 WLC running 7.6.130.0 so when a Web-Auth users tries to authenticate they don't get the SSL cert error.
In the document "Generate CSR for Third−Party Certificates and
Download Chained Certificates to the WLC"
Document ID: 109597 it states the following
"Note: It is important that you provide the correct Common Name. Ensure that the host name that is
used to create the certificate (Common Name) matches the Domain Name System (DNS) host name
entry for the virtual interface IP on the WLC and that the name exists in the DNS as well. Also, after
you make the change to the VIP interface, you must reboot the system in order for this change to take
effect.
Here are my questions.
1. I have always had 1.1.1.1 as the address of the Virtual interface, should that change or can I leave it as 1.1.1.1?
2. In the "DNS Host Name" Field do I simply put the domain or the FQDN? Example. Company.com or hostname.company.com

Hi,
1) You can change that if you want. Normally it is non-Public and non-routable in your network.
2) Put the Host name for which you are going to give in your company DNS server where that Host name would be mapped to the Virtual ip address.

WLC 2106 CSR Request For Web Authentication

Greetings, ive been following the guide below in order to replace the web auth certficate for guest users on our WLC2106.
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00806e367a.shtml
Does anyone know of a method of using Windows 2003 CA Services to sign the CSR, i have tried but i can't get a PEM out of it, just X509 and P7B Certs, i do realise that Guest Users not native to our network will still be presented with an invalid certificate option but would like to try the configuration before paying to have the certificate properly signed.
Regards

This document assumes that the CA server configuration on the Microsoft Windows 2003 server is in place. This document covers the configuration required on the Wireless LAN controller in order to enable this feature.

Is there a way to store credientials for Web authentication?

I use an IPAD in my corporate network and have this nagging problem of "dropped wifi" after some idle minutes. True, this forced drop out could be due to my corporate router security settings (although they swear it is not there) but here is what frustrates me:
1. That a Samsung tab works on the same floor in the office (on same wifi network) without dropping frequently.
2. That if the Samsung tab's connection does drop once in a while, it can reconnect quickly. This is because it stores the web site id, user id and password.
My question is why can't an IPAD store the router website url and user id and password that is needed to re login?
If anybody else encounters this issue on an airport or a hotel room, please let us work for the solution togther.

I have migrated everything from my windows PC to my new Apple Mac, except for all my Outlook information. Thunderbird recreated the information, but without an "sbd" ext

I have tried Thunderbird to migrate all my Outlook mail, contacts and address information from Windows to Mac but it didn't work. It didn't give me an 'sbd' extension even though it recreated allmy information in Thunderbird. There was no way for me to export the information from my Windows PC to my new Mac. Can anyone please help me.
Gail1401

O2M (Outlook2Mac) is the only migration app that I have ever found that works to migrate Outlook pc mail, contact, and calendar data to a Mac. At $12.95 it's a steal.
It sounds like what you actually did was import your Outlook mail on your pc to Thunderbird on your pc.
Note 1: O2M runs on your pc. It converts your Outlook files to a format that can be transferred to a Mac. After you export your Outlook mail & contacts you still need to move (copy) them to your Mac and import them into whatever mail/contact application you are using on your Mac.
What mail/contact application are you planning to use on your Mac?
Do you need assistance with copying files from your pc to your Mac?
Note 2: .sbd files are Thunderbird files. They are optional and are associated with Thunderbird mail subfolders. They have no bearing on migration from a pc to a Mac.

So i will explain problems what i have seen:
SSID: DTS-Group using authentication EAP with RADIUS and it working great (Authentication Type from Aironet to RADIUS is PEAP)
SSID:L6-Webauthen-test using web-auth and i had try to compare with RADIUS but ROOT CAUSE is AUTHENTICATION TYPE from Aironet to RADIUS default is PAP. (Reason Code : 66)
=> I had trying to find how to change Authentication Type of Web-Auth on Cisco Aironet from PAP to PEAP or sometime like that for combine with RADIUS.
Any idea or recommend for me ?
Thanks for see my case

Hi Dhiresh Yadav,
Many thanks for your reply me,
I will explain again for clear my problems.
At this case, i had setup complete SSID DTS-Group use authentication with security as PEAP combine Radius Server running on Window 2008.
I had login SSID by Account create in AD =>  It's work okay with me. Done
Problems occurs when i try to use Web-authentication on Vlan45 With SSID :
dot11 ssid L6-Webauthen-test
vlan 45
web-auth
authentication open
dot1x eap profile DTSGROUP
mbssid guest-mode
After configured on Aironet and Window Radius , i had try to login with Account create in AD by WebBrowser but it Fail ( i have see mini popup said: Authentication Fail" . So i go to Radius Server and search log on EventViewer.
This is My Logfile on Radius Win 2008 :

Im think ROOT CAUSE is :
PAP is the default authentication type for web-auth users on Aironet 2702i, so it can't combine with Radius Window 2008 because they just support PEAP (CHAPv1,CHAPv2....) => Please give me a tip how to change Authentication Type from PAP to PEAP for Web Authentication on Aironet

Client Excluded ReasonCode on WLC for Web Auth

Hi.
I wonder if you can point me at a table that defines the Reason Code(s) for Client Exclusion Failure? See the example event log entry below from a Guest Controller for Web Authentication failure (that was resolved - Internet router down) but I was wondering if the Reason Codes would be useful in troubleshooting. Many thanks in advance.
Tue Aug 28 10:45:31 2007 Client Excluded: MACAddress:00:16:6f:b3:20:0a Base Radio MAC :00:00:00:00:00:00 Slot: 0 Reason:Web Authentication failed 3 times. ReasonCode: 4

I haven't tried it recently. But I'm afraid of this one :
CSCsy88149 Chained certificate can not have Wildcard * character in hostname
Even if bought at verisign or any root CA, your cert has a good chance of being chained since they very often use an intermediate CA. I know wildcard certs are supported but this bug seems to say that it doesn't work for chained.
again, I didn't verify it mysefl

Hello Yuliang,
The maximum number of local database accounts that could be created is 2048. You can configure the size of the local database with the command:
config database size <512-2048>
NOTE: This local database count is shared between the following entries:
MAC filters (clients)
AP MIC/SSC (AP authorization list)
Dynamic Interfaces
Management users
Local net users
Excluded Clients
If you are asking about the number of simultaneous wireless clients, I believe the 2125 supports 350 active wireless clients.

RGB Colour change after save for web.

I recently had a folder full of images that I cut out and placed on a grey #e9e9e9 background, after using adobe photoshops Save for web feature, I saved them as 356 colour gif files. However when Ive uploaded them to the web I notice the grey #e9e9e9 was ever so slighty different. when I reopened the images in .gif files in photoshop, the grey background was no longer #e9e9e9 but #eaeaea. Im slighty confused as to why this has happened, and is there anyway of correcting this?

It depends on the mode:
Perceptual
Selective
Adaptive
In my tests Selective preserves larger gray
areas e9e9e9 (233 233 233). I think there is no
guarantee, except for web-safe colors (which are
otherwise quite useless nowadays).
