Guest Portal - untrusted certificate

All,
My ISE integration is on our local domain,for example company.local. I created a rule in the authorization policy that used a static IP address, say guest.company.com for our guests to use for the redirection. When guests get the web auth redirection to guest.company.com they are getting the untrusted certificate.
I tried to import a certificate from our external CA, and faced errors because it didnt have the .company.local SAN. I did generate that with the CSR but my external CA doesnt give me an option to include this.
How is this rectified so our guests hit the web portal without getting a certificate error?

Hi Jason,
From my experience, this is a common problem. Typically, what I do on deployments is obtain a trusted 3rd-party signed certificate for my HTTPS usage on the ISE appliances. If you want to use your internal CA certificate to authenticate EAP for your domain computers and other sessions, you can still do so.
Note: Sometime in 2014 (it may already be active) the 3rd-party certificate signers are no longer going to allow .local or other internal domains on their certificates.
With that said, I've normally been deploying the ISE appliances with an external domain name, example, ise.company.com rather than ise.company.local. You can setup split DNS on your network to allow ise.company.com to resolve to your internal IP.
Hope this helps.

ISE Guest portal digital public certificate with dual deployment

I have a deployment of ISe which has a primary and secondary node. We are using ISE for Guest web access and it's Guest portal functionality.
I have installed a public VeriSign certificate onto the primary node so that guest users don't certificate errors when they get redirected to the guest portal.
We have a DNS server with an entty for the guest portal URL e.g. guest.company.com with the IP adresses of both ISE servers.
When users are loggin onto the guest wireless it is pot luck whether or not they get the primary ISE node because of the DNS round robin of the ISE IP addresses.
Is there anyway to make the secondary ISE node use the Verisign certificate as well or do I need to buy another certificate which is linked to the secondary ISE nodes FQDN?
(the certificate I have currently has a CN of the FQDN of the primary ISE server with subject alternative names of the secondary ISE node and the guest web redirect URL).
Any help would very much be appreciated.
thanks

How to use ISE Guest Portal for AD users

Hi there,
As subject explains all, I want to use ISE Guest Portal for my domain users. I have tried many different ways to authenticate users and finally I came to the conclusion that ISE CWA works pretty well and is very stable. WLC Webauth sucks alot, does not redirect to the login page always.
Can you please share what other ways are stable ways to authenticate AD users? I know about WPA 802.1x authentication but that requires a CA in the network which is not available at the moment. So can you please Suggect?
Otherwise, I want to use ISE Guest Portal for my AD users as well. AD is already integrated to ISE, the issue happens when I attempt to athenticate using AD user account, the user gets authenticated but the Guest Portal redirects me to Device Provissioning page and there it shows an error saying "there is not policy to register the device, contact system admin"
Am I missing something??
I am running WLC 5760 with ISE 1.2
Thanks in advance..

Hi,
Can you post a screenshot of your current policies? Also for 802.1x authentication although it is best practices you do not have to have an internal CA to make this solution work. You can disable the option to "validate server certificate" or you can use a trusted CA to sign the certificate for the eap interface.
In most cases 802.1x is the method to go because it provides dynamic authentication without forcing users to redirected to a web page multiple times throughout the day, scenarios such as computers that sleep or users that are mobile will not have connectivity until they redirect to the portal if one of the scenarios exist. You also gain WPA encryption on your WLAN, if you are using strictly layer 3 web auth you run into issues where encryption is not used and rely on encryption from the application as your method of data integrity and security.

Ise 1.2, cannot access guest portal

I upgraded from 1.1.4 patch 3 to 1.2 but cannot access guest portal anymore nor with FQDN:8443 nor with IP:8443
any idea?

I had attached the steps to configure the guest portal and hope will address the problem.
Configuring the Guest Portal
Adding a New Guest Portal You must configure settings for the Guest portal before allowing guests to use it to access the network. Some settings apply globally to all Guest portals and other require you to set them for each portal individually.
You can add a new Guest portal or edit an existing one.
Step 1Choose Administration > Web Portal Management > Settings > Guest > Multi-Portal Configurations.
Step 2Click Add.
Step 3Update the fields on each of these tabs:
•General—enter a portal name and description and choose a portal type.
•Operations—enable the customizations for the specific portal
•Customization—choose a language template for displaying the Guest portal with localized content
•File Uploads—displays only if you have chosen a portal type requiring you to upload custom HTML files.
•File Mapping— identify and choose the HTML files uploaded for the particular guest pages. Displays only if you have chosen a portal type requiring you to upload custom HTML files.
•Authentication—indicate how users should be authenticated during guest login.
Step 4Click Submit.
Specifying Ports and Ethernet Interfaces for End-User Portals
You can specify the port used for each web portal allowing you to use different ports for the end-user portals: Sponsor, Guest (and Client Provisioning), My Devices, and Blacklist portals. The Client Provisioning portal uses ports 8905 and 8909 for posture assessments and remediation, which you cannot change. Otherwise, it uses the same ports assigned to the Guest portal.
You can also partition portal traffic to specific Gigabit Ethernet interfaces. For example, you might not want the Admin portal (which always uses GigabitEthernet 0) available on the same network as guest users or employee devices.
Step 1Choose Administration > Web Portal Management > Settings > General > Ports.
Step 2Enter the port value in the HTTPS Port field for each portal. By default, the Sponsor, Guest, My Devices portals use 8443, and the Blacklist portal uses port 8444.
Step 3Check the Gigabit Ethernet interfaces you want to enable for each portal.
Step 4Click Save.
If you have changed the port settings, all nodes (Administration, Policy Services, and Monitoring) restart automatically, which may take several hours to complete.
Tips for Assigning Ports and Ethernet Interfaces
•All port assignments must be between 8000-8999. This port range restriction is new in Cisco ISE 1.2. If you upgraded with port values outside this range, they are honored until you make any change to this page. If you make any change to this page, you must update the port setting to comply with this restriction.
•You must assign the Blacklist portal to use a different port than the other end-user portals.
•Any portals assigned to the same HTTPS port also use the same Ethernet interfaces. For example, if you assign both the Sponsor and My Devices portals to port 8443, and you disable GigabitEthernet 0 on the Sponsor portal, that interface is also automatically disabled for the My Devices portal.
•You must configure the Ethernet interfaces using IP addresses on different subnets. Refer to these guidelines to help you decide how best to assign ports and Ethernet interfaces to the end-user portals:
Specifying the Fully Qualified Domain Name for Sponsor and My Devices Portals
You can set the Sponsor and My Devices portals to use an easy-to-remember fully-qualified domain names (FQDN), such as: mydevices.companyname.com or sponsor.companyname.com. Alternatively, Cisco ISE also supports wildcard certificates to address certificate name mismatch issues. You must configure DNS to resolve to at least one policy services node. If you have more than one policy services node that will provide portal services, you should configure high availability for the portal. For example, you could use a load balancer or DNS round-robin services.
Before You Begin
Step 1Choose Administration > Web Portal Management > Settings > General > Ports.
Step 2Scroll to the Portal FQDNs section, and check the appropriate setting:
•Default Sponsor Portal FQDN
•Default My Devices Portal FQDN
Step 3Enter a fully qualified domain name.
Step 4Click Save, and all nodes (Administration, Policy Services, and Monitoring) restart automatically, which may take several hours to complete.
Step 5Configure the network DNS server so that it resolves the FQDN to the Sponsor or My Devices portal nodes. You must also update DNS to ensure the FQDN of the new URL resolves to a valid policy service node IP address. Additionally, to avoid certificate warning messages due to name mismatches, you should also include the FQDN of the customized URL in the subject alternative name (SAN) attribute of the local server certificate of the Cisco ISE policy service node.

Guest Portal with EUP Page Only

I have a use case to provide a guest portal with EUP page only. ie. user only needs to accept the agreement and they should be given internet access, without need to enter username/password or self service. Is there an easy way to achieve this on ISE 1.2?
Thanks in advance.

Hi Mark,
Yes Guest Cert will need to be external. Because Guest Users if they have a non-corporate laptop for example will not have your Internal Company Certs installed in their browser (that you loaded onto ISE), so they cannot trust your internal Cert.
If your open Firefox or IE under Options/Security View Certificates you will see a list, if its a Guest you will see well known public Certs like Geotrust, Verisign etc.
For my setup I brought a GeoTrust cert and loaded this into ISE, this way Guests will always Trust the Geostrust ISE cert like https://guest.com for example and the login will appear and be trusted.

ISE Guest Portal

Hello Everyone
Is it possible to have a WLC 4402 and a WLC 5508 working with the Guest portal of the ISE at the same time?
I know that for the WLC 5508, it works fine and i can implement this as CWA, but for the WLC 4402? i read something about change the certificate in the ISE in order to have it as LWA, but can this affect the CWA implemmentation?
Thanks for any suggestion.

Sending LWA and CWA authentications to the same guest portal won't be a problem.To keep things nice and clean though you can create a second HTML portal so you can dedicate one per each process but it is not necessary.
Hope this helps!
Thank you for rating helpful posts!

ISE HTTP GUEST PORTAL

Hello,
We have some disconfort with Guest web authentication. When WLC redirects a guest user, he views certificate error.
Can I use http instead https for guest portal?
Thanks,
Oleg

Hi,
Is your guest portal on the ISE ? In the ISE , there is only HTTPS port allowed to configure under Guest portal and no option of http port is there , So I dont think so. You also might be using port 8443 in the external web-auth redirection URL under security tab.
Now even if you put a valid certificate on the ISE which hosts external guest portal , still you would receive certificate warning as long as you use local web server of the controller which is its virtual ip address.This is because even if the external web server where page is hosted for example has a valid certificate , even then internal virtual ip address is presented to the client.
So
> either you trust them in your browser so that you dont receive certificate warnings
>or else have a valid certificate on the controller and external web server.
> or use http for web authentication in the controller and also http to external hosted page, then also you can get rid of these certificates.

Activate custom guest portal in ISE

This question must sound stupid, but I'm struggling with it four two days now without success:
I've managed to upload custom HTML files for a custom guest portal via
Administration -> Web Portal Management ->Settings -> Guest -> Multi-Portal Management
and assigned files for the four required File Mappings (Login, AUP, Guest Success, Error)
However, where do I configure that this custom portal is actually used?
The only observable Difference to the DefaultGuestPortal I find is that under Authentication, it has the setting Identity Store Sequence = Guest_Portal_Sequence (greyed out) while my custom portal has this field empty (and also greyed out).
I merely found in the docs that the redirection URL should be schanged to mathc the portal name. However, my guess is that this URL is a RADIUS option and should thus be configurable on the ISE - somewhere, but I found nothing.
(While we're at it: Where can I configure the redirection to take place with hostname instead of ip? All examples in docs seem to use ip, but that is of course ridiculous in connection with https as it makes the use of certificates from well-known CAs impossible)

ISE 1.2 customizing guest portal

I am having some issues trying to customize colours on the default guest portal in ISE 1.2.
Is there really no way to change the entire page background colour, except going through creating a complete set of html files ?
It seems if i upload a transparent background image for both the banner and the logo, and then change the all the gackground coulour settings, the colour only affects the area where the cisco splash logo is, and not the entire page.
I attached my settings, and how the page looks with those, what i am after is the entire page black, and then white text.

Hello Jan
You can customize the look-and-feel of the end-user portals by uploading your company's logos, background images, or color schemes. These changes apply to the My Devices, Sponsor, and Guest portals, but you can assign different images and colors to the mobile Guest portal.
These settings allow you to change the appearance of the portals without having to upload customized HTML files to the Cisco ISE server. However, if you want to create themes unique to specific Guest portals, you must upload your custom HTML files instead.
Step 1 Choose Administration > Web Portal Management > Settings > General > Portal Theme.
Step 2 Upload the graphics and change the color settings in the Style Settings section to customize the standard portals.
Step 3 Upload the graphics and change the color settings in the Mobile Device Style Settings to customize the Guest mobile portal.
Step 4 Click Save.

5760 v3.6 guest portal redirect to ISE

I'm testing a new set of 5760 controllers for a future production rollout, running software version 3.6. Our current production setup consists of older WISM-1 and 4402 controllers running CUWN 7.0. Our guest network has an anchor in the DMZ, redirecting to ISE.
In the recent thread (https://supportforums.cisco.com/discussion/12319151/3850-ise-guestportal-no-redirect-v-334), one of the posters said that guest redirection in 3.6 works similarly to redirection in CUWN, while in 3.3 it is very different. I found the documentation for 3.3 (http://www.cisco.com/c/en/us/support/docs/wireless/5700-series-wireless-lan-controllers/117717-config-wlc-00.html), which I have to say I don't like very much. However, I find the configuration and command reference guides for 3.6 are less than helpful on this point.
So the question I have is whether guest networking with an external redirect to ISE looks like the following in 3.6? Or does it work like CUWN, where the SSID is configured with layer 3 security? If it uses layer 3 security like CUWN, does anybody have a quick configuration sample for how it can work end to end in 3.6?
------ From the document http://www.cisco.com/c/en/us/support/docs/wireless/5700-series-wireless-lan-controllers/117717-config-wlc-00.html ---------
The flow includes these steps:
The user associates to the web authentication Service Set Identifier (SSID), which is in fact open+macfiltering and no Layer 3 security.
The user opens the browser.
The WLC redirects to the guest portal.
The user authenticates on the portal.
The ISE sends a RADIUS Change of Authorization (CoA - UDP Port 1700) in order to indicate to the controller that the user is valid, and eventually pushes RADIUS attributes such as the Access Control List (ACL).
The user is prompted to retry the original URL.

I have a project with a 5760 running 3.6 working to a 5508 anchor controller in a DMZ.
I have web authentication working to an ISE OK.

ISE 1.2.1.198 - Guest Portal Configuration

Is it possible to customize the default portal and add a paragraph any where on the login page with instructions? I've tried adding the text in the Pre-Login Banner Text field, and it does wrap to the next line, but text goes of the screen before wrapping. Would like to be able to add carriage return in the text, so text would scroll off the screen.

ISE 1.3 (due out in November time frame) will have a huge amount of customization of the portal available for your use.
If you really need to do it before then, and you have an ISE-certified Authorized Technology Partner you're working with, they have access to a Guest Portal Builder tool that can be used.
Failing those, you're back to changing the native html code for the portal by hand. Not recommended.

ISE 1.2 Guest Portal - Device registration portal

Hello,
I have a problem with the following setup:
- Cisco ISE 1.2 (latest patch)
- Cisco WiSM with 7.0.220.0 (first generation)
I have build Guest access via ISE. Because the WiSM's highest version is 7.0.X I used LWA with a redirect to the ISE guest portal. When using the Guest SSID with a iPad the client is redirected to the ISE guest portal and the user can enter his credentials (deliverd by the Sponsor). After clicking "Sign On" the client is forwarded to the "Device Registration Portal" of ISE and need to register his MAC address.
We have try a lot of differend settings but we cannot switch off the forward to the "Device Registration Portal". We only want to use the Guest User portal.
Please can someone help me to find a solution for this problem?
Thank you in advance.

I know this might be reaching, but have you turned off the My Devices portal?
If so, an idea of the different settings you have already tried might help.

ISE 1.2 Guest Portal - This device has not been registered.

I have setup and SSID on my WLC. I got the redirecting to my ISE guestportal working.
However when I sign in I get a Device regitration Page
"This device has not been registered"
Unable to obtain the user information needed for network access.
The device ID is grayed out and blank.
Any assistance in this matter would be greatly appreciated

Thanks Johnston,
P.S for those who needs the path ISE 1.2 Administration -> Web Portal Management -> Settings -> Multi-Portal Configurations -> DefaultGuestPortal -> Operations.
On another note
When I login - I get my acceptable usage policy.
Accept
Then get a Device registration Portal where I can add the MAC address.
Now I have two quistions.
When I add my test mac address the url redirects to myservername:8443/guestportal/AfterDevReg.action - unable to connect <- that's the one issue.
The other is - Can't I by pass the MAC? ie once the user is signed on to get access.
Curretly I have the following settings enabled.
Enable Mobile Portal
Allow guest users to change password
Guest users should be allowed to do device registration <- if I disable that after signon the page just flash back to the guest portal.

ISE 1.2 Guest portal user cannot change their passwords

I have a WLC 5508(version 7.6) and a server installed the ISE (version 1.2.1.198)，Now we configured the CWA，Use guest portal as an employee and guest login url，We can use the manually create internal user and password successfully logged in, and we set up allow guest users to change password in Multi-Portal, but the user can not change the password in the guest portal ,I suspect the change password option on the Guest Portal actually works? Can anyone tell me how to change their own username password in the guest portal ?

Requiring Guests to Change Password
You can allow or require guest users to change their password after their initial account credentials are created by the sponsor. If guest users change their passwords, sponsors cannot provide guests with their login credentials if they are lost. The sponsor must create a new guest account.
You can either allow guests to change their passwords, or you can require that they do it at expiration and at first login. To require internal users using a guest portal to change their password upon their next login, choose Administration > Identity Management > Identities > Users . Select the specific internal user from the Network Access Users list and enable the change password check box.
Before You Begin
Create a Guest portal or modify the DefaultGuestPortal. This setting is specific to each Guest portal.
Step 1 Choose Administration > Web Portal Management > Settings > Guest > Multi-Portal Configuration.
Step 2 Check the Guest portal to update and click Edit .
Step 3 Click the Operations tab.
Step 4 Check either or both options:
Allow guest users to change password
Require guest users to change password at expiration and first login
Step 5 Click Save .
