ISE, BYOD: guest clients provisioning

Hello!
The question is about provisioning different types of wifi clients through the ISE Guest portal.
ISE 1.1.4, WLC 7.4.100 (Guest WLAN uses MAB)
Suppose, there are two groups of wireless clients:
1) guest user, which credentials are created through the ISE Sponsor Portal
2) domain user, who has credentials in ActiveDirectory
The aim is to provision domain user, and not provision guest user.
When client connects to Guest SSID and opens the browser, he is redirected to ISE Guest portal.
When client uses domain user, he is provisioned, and when uses guest credentials he is not provisioned
How ISE understands, that domain user must be provisioned and guest user must not be provisioned if Web portal is configured to provision everyone?
(Web Portal -> Settings -> Enable Self-Provisioning flow)

The answer is that typically you either know that MAC address or you have someting installed (NAC agent?) and fulfill some requirements.
Alternative, you can perform CWA first (and...)
Then if user is part of guest users -> allow internet only access
If user is part of AD -> send him to do registration.
Authorization policy allows you to use "identity group" as part of condition.
If device registered -> allow full access. (just an idea).

ISE 1.2 Client Provisioning Page Customization

Hi All,
Is it possible to customize Client Provisioning Page. We are using ISE version1.2
I could see from switch port authentication sesssion that it is being redirected to guest portal with session ID.
however on the host machine itself it gets redirected to a different URL.
Regards
Sameer

please have a look on Configuring Client Provisioning guide:

Cisco ISE 802.1X Client Provisioning

Hi,
I have a requirement for ISE client provisioning for both Windows and mac. I have the following setup:
1. 2 SSIDs, Guest and Employee
2. Guest is open access
3. Employee is 802.1x eap-peap (username/password)
I was wondering if client local administrator privillege is required for 802.1x provisioning for windows client? I believe it is required for MAC OS however not too sure if it may be required for Windows?
Example Employee A connect to Guest SSID and is redirect to the guest web portal. Upon login, they will be presented with the device registration portal. Upon being presented by the ISE on the supplication wizard, will they be requested for local administrator/domain admin privillege to install the supplicant wizard package/provisioning agent successfully?
Any suggestion is appreciated.
Thanks.

Hi,
Appreciate for the feedback.
Thanks

ISE, BYOD: win clients reject ISE local-certificate

Hello!
We are deploying BYOD with Cisco ISE 1.1.2 and WLC (5508) using 802.1x authentication.
Windows clients cannot connect to 802.1x SSID with the following error on ISE:
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
The client doesn't have preconfigured wifi profile or root certificate installed.
The concept of BYOD suppose that you can connect your device without any installed certificates and preconfigured wifi-profiles.
The problem is that Windows 7 supplicant does not send TLS alert in pop up window, when connecting to 802.1x SSID.
If this alert is seen, than you can accept it and proceed the connection. After that you will be asked to install ROOT-cert, get your own cert and etc.
So, the question is: how to make the windows supplicant to show the pop-up window with TLS alert?
p.s. the attached file shows the example of pop up TLS-alert window

Are there any recommendations from Cisco about the issue with Windows?
I believe there's a new version of smart solution design guide coming up.
The current one does not mention anything to do with certs in "User Experience" chapter.
You can check one of the possible approaches in Nico's document:
http://www.cisco.com/en/US/products/ps11640/products_configuration_example09186a0080bead09.shtml
(It can be easily expended).
I think irt. PEAP we will always say that the cert or the root/sub CA cert should be already trusted on the device when perfoming enrollment.
Will try to dig in, can't say I promise to get something concrete though.

ISE 1.0 Posture and Client provisioning

I've configured 802.1x with dynamic VLAN for users and MAB for phones - it works fine. Now I wanna to implement client provisioning and posture validation for users. After reading ISE user guide there are still several big questions:
1. Is it possible to combine 802.1x and posture? (it was not recommended with NAC)
2. How can I bind existing 802.1x authorization profile and posture policy?
3. What is a switch configuration for client provisioning to work(redirect, quarantine zone, download NAC agent)?
4. Do ISE posture and client provisioning have L2 virtual gateway, trusted and untrusted ports, as in NAC?

With ISE you can perform 802.1x first and after that optionally you can perform posture. This is done with Radius, that's why it's really and completely out of band, and there's no such concept of trusted or untrusted port because the traffic is never inline.
Still, with ISE you have another option of "inline Posture", in which there's trusted and untrusted ports. I guess that's for some specific cases in which you can't go out-of-band.
On the other hand, so called "out-of-band" NAC was really always an inline solution, only after the user has authenticated and security policies have been verified then the user goes "out-of-band".

ISE , BYOD iphone issue!! client provisioning

Guys, when i sent down a profile using native suplicant for iphone, iphone gets it but it does not automatically selects TLS on the SSID.
Here is what happens:
Iphone connects to BOYD-SSID
credentials enter
client provision process
** if Auto-Login is selected problem with self registration!!!!!!!!
bunch of security errors, profile is downloaded
iphone reconnects to BOYD_SSID with credentials initilly entered (therfor MSCHAPv) not TLS
in client provisining cycle.
NOW!!!!
go back to BYOD-SSID and "forget the network", reconnect again, and manually selecting TLS and using the profile previously downloaded, and everything works!!!!
Too many freaking steps for BYOD!!!! I can't have my client tell his employees to do that.
ANy ideas.....

Marcin,
I have not had the problems you are discussing, what version of code are you running and I assume you are using the single-ssid method? In my experience I have seen where the new profile over-writes the old peap profile and after COA hits the client then uses eap-tls to connect.
Can you provide screenshots of the experiences you are having?
Thanks,
Tarik Admani

ISE 1.2 device registration with MAB only, no client provisioning

Hello,
Is it possible for AD users (no guest users) to walk through the Device Registration Self Registration without Client Provisioning ?
I do not want to push certificates or native supplicant profiles to client devices.
I would just want AD users to register their MAC address, if MAC is not known. Add the MAC to some sort of group.
Then if MAC is known (in this group), skip registration and allow full access to the VLAN.
Right now, i am stuck on the registration portal that says "The system adminstrator has either nog configured or enabled a policy for your device". ?? It is true that my Client Provisioning screen is empty.
Am i really obliged to use native supplicant provisioning to register my device ?

Hi
Device Registration web auth is a process where you can configure user without client provisioning.
In this scenario, the guest user connects to the network with a wireless connection that sends an initial MAB request to the Cisco ISE node. If the user’s MAC address is not in the endpoint identity store or is not marked with an AUP accepted attribute set to true, ISE responds with a URL redirection authorization profile. The URL redirection presents the user with an AUP acceptance page when the user attempts to go to any URL.
1. A guest user connects to the network using a wireless connection and has a MAC address that is not in the endpoint identity store or is not marked with an AUP accepted attribute set to true, and receives a URL redirection authorization profile. The URL redirection presents the user with a AUP acceptance page when the guest user attempts to go to any URL.
2. If the guest user accepts the AUP, their MAC address is registered as a new endpoint in the endpoint identity store (assuming the endpoint does not already exist). The new endpoint is marked with an AUP accepted attribute set to true, to track the user’s acceptance of the AUP. An administrator can then assign an endpoint identity group to the endpoint, making a selection from the Guest Management Multi-Portal Configurations page.
3. If the guest’s endpoint already exists in the endpoint identity store, the AUP accepted attribute is set to true on the existing endpoint. The endpoint’s identity group is then automatically changed to the value selected in the Guest Management Multi-Portal Configurations page.
4. If the user does not accept the AUP or an error occurs in the creation of the endpoint, an error page appears.
5. After the endpoint is created or updated, a success page appears, followed by a CoA termination being sent to the NAD/WLC.
6. After the CoA, the NAD/WLC reauthenticates the user’s connection with a new MAB request. The new authentication finds the endpoint with its associated endpoint identity group, and returns the configured access to the NAD/WLC.

Client provisioning exception for guest flow - bug?

hi all,
I encounterd one problem with guest flow and client provisioning.
Please if someone could confirm that this can or can't be done
I want to accomplish such a scenario:
- AD user have to download the full nac agent
- AD user from specific group when using webauthentication (as a fallback) doesn't need to downlaod webagent (so no posture at all - the default status is compliant)
- all guest users need to download webagent
It seems that it can't be done cause:
First of all to make it work we need to enable "guest users should download the posture client"
I created the "client provisioning policy" in a way that:
If it is AD user and its not a guest flow (2) then NAC agent should be applied
If it is a guest user webagent should be downloaded
It works with an exception that when AD user logs in using webauthentication (guest portal), no download page is displayed (as expected) but instead of normal access there is a blank page with the following URL
https://ise-nfr.sevenetdemo.local:8443/auth/CppSetup.action
so it seems that even though there is no match in "client Provisioing Policy" (again, as expected) ISE still tries to redirect to the cpp portal as this checkbox in multiportal configuration says so.
As a result no CoA is initiated to the switch and switch authentication hangs on the last default policy - CWA_POSTURE_REMEDIATION
Is it possible to do it?

Przemek

Client provisioning not working on ISE after 1.2 Migration

Working on an initial piloted roleout of ISE with a customer. We initially had a single server setup as a pilot using 1.1.1.4 to pilot things like client supplicant provision, and then stood up a new VM as a secondary and upgraded that to 1.2. Today we tested client provisioning that work fine before, and it is failing for iOS (we haven't gotten to the other OS'es yet). What occurs is the user authenticates using PEAP and the client gets the request to install the root certificate. After this the client accepts the root certificate the connection drops. When you click the SSID to start the process again we see the redirect to the mydevices portal, but before you can click to register the client it redirected to accept the root certificate again, creating an endless loop. Has anyone else run into this bug?

Cisco ISE (1.3) Posture without Client Provisioning

Hello readers,
Is it possible to set up Cisco ISE with posture without Client Provisioning?
My customer deploys the NAC Agent via MS SCCM. We prefer a access accept + DACL during the pending state instead of redirecting to client provisioning. But the NAC Agent will only communicate when we redirect to client provisioning.

Dennis

With ISE you can perform 802.1x first and after that optionally you can perform posture. This is done with Radius, that's why it's really and completely out of band, and there's no such concept of trusted or untrusted port because the traffic is never inline.

ISE Posture to guest clients

Hi Guys,
i'd like to know if is it possible to make a posture to Guest Clients using the Web Agent after they had been login into the portal.
thanks

Of Course it is possible. For detailed information please review the following guide
Configuring Client Posture Policies
http://www.cisco.com/en/US/docs/security/ise/1.1.1/user_guide/ise_client_prov.html
You can also create posture-specific authorization policies for all wired, wireless, and guest deployments by
specifying the Session:PostureStatus attribute in the authorization policies. This attribute has three
values, unknown, compliant, and noncompliant, which you can use n the authorization policies

Using ISE for guest access together with anchor controller WLC in DMZ

Hi there,
I setup a guest WLAN in our LAB environment. I have one internal WLC connection to an anchor controller in our DMZ. I'm using the WLC integrated web-auth portal which works fine.
To gain more flexibility regarding guest account provisioning and reporting my idea is to use Cisco Identity Services Engine (ISE) for web-authentication. So the anchor controller in the DMZ would redirect the guest clients to the ISE portal.
As the ISE is located on the internal network while the guest clients end up in the DMZ network this would mean that I have to open the web-auth portal port of ISE for all guest client IPs in order to be able to authenticate.
Does anyone know of a better solution for this ? Where to place the ISE for this scenario, etc ?
Thx
Frank

So i ran into a similar scenario on a recent deployment:
We had the following:
WLC-A on private network (Inside)
ISE Servers ISE01 and ISE02 (Inside)
WLC-B Anchor in DMZ for Guest traffic (DMZ)
ISE Server 3 (DMZ)
ISE01 and ISE02 are used for 802.1X for the private network WLAN.
Customer does not allow guest traffic to move from a less secure network to a more secure network (Compliance reasons).
The foreign controller (WLC-A) must handle all L2 authentication and it must use the same policy node that the clients will hit for web auth. Since we want to do CWA, we use Mac Filtering with ISE as the radius server. If you send this traffic RADIUS authentication for Mac Filtering to ISE01/ISE02, it will use https://ise01.mydomain.com/... to redirect the client to. Since we don't allow traffic to traverse from the DMZ with the anchor in it back inside to the network where ISE01 and ISE02 are, client redirection fails. (This was a limitation of ISE 1.1. Not sure if this persists in 1.2 or not.
So what now? In our deployment we decided to use a 3rd ISE policy node (ISE03 in the DMZ) for guest authentiction from the Foreign controller so that the client will use a DNS of https://ise03.mydomain.com/... to redirect the client to. Once the session is authenticated, ISE03 will send a CoA back to the foreign which will remove the redirect for the session. Note, you do have to allow ISE03 to send a CoA.
In summary, if you can't allow guest traffic to head back inside the network to hit the CWA portal, you must add a policy node in a DMZ to use for the CWA portal so they have a resolvable and reachable policy node.

Client provisioning issue

Hi, I configured client provisioning for guests. and it does not work.
I checked client provisioning,device registration on defaultguestportal, and configured client provisioning like this
OS:windows all and nas port type equls wireless802.11
but when I create guest user id, and login, there is no client provisioning going on. it just shows success page.
do you know why it is working not propery ?

ISE and Guest Portal

WLC - 7.2.110.0
ISE - 1.1.1
I'm new to ISE. I want to set up a very basic method for BYOD users to access our wireless network. I've set up an SSID for external Web Auth, where users get redirected to the ISE Guest Portal: https://1.2.3.4:8443/guestportal/Login.action
At that screen, users can enter their Active Directory credentials and login. Although the authentcation shows as successful under Operations -> Authentications, the user is redirected to the device registration page. On that page they see the message "We are unable to determine access privileges in order to access the network. Please contact your administrator." Their device MAC is listed, and they can enter a description but the "Register" button is greyed out.
I'm getting overwhelmed with the amount of documentation available as well as the new terminology. I'm familiar with using Windows RADIUS servers, but ISE is very foreign to me now. Is there any documentation to help me understand how access requests are processed?

As you asked the documents related to ISE and Guest Portal. I am sending you two docs which will help you in this case. Please find the below documents:
