Cisco ISE Local Web Authentication via Switch

Hello,
I have Cisco ISE 1.2 and I need local webauthentication for clients.
I want to send webauthentication link via switch.
I made a research for it but I meet ACS documents :
http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Security/TrustSec_1-99/WebAuth/WebAuth_Dep_Guide.html#wp393321
and ISE central webauthentication documents for it.
Is there local webauth in ISE via switch?
Thanks,
Alparslan

Cisco Ise Central Web authentication not working

Hello Guys,
CWA is not working. It says that authentication suceeded but posture status is pending. No error in my Monitor--authentication. Checking it in my Windows 7, it does not shows the CWA portal.
What might be the possible problem of this.?
thanks

Kindly review the below links:

Local Web Authentication Started after Central Web Authentication

Hi everyone,
We have a DMZ based anchor WLC for a guest WLAN. I have this WLAN configured for central web authentication using ISE 1.2, this works correctly and can login using the guest portal.
However, after logging when browsing to a website everything is redirected to the local web authentication page and the policy manager state for the client goes in to a WEBAUTH_REQD state. I currently don't have any layer 3 security configured for this WLAN, so from my understanding it should just be using the central authentication provided by ISE.
Thanks for your help.
Mark

Hi Mark,
Thanks - that looks very similar to ours, though I'm doing the 3850 via the CLI as the web UI keeps dying when I click into things.
I've realsed that I unticked the Authentication servers box instead of the Accounting as I miss-read the WLC page, however while the LWA no-longer kicks in, I'm unable to pass anything except DNS traffic. The Anchor says that the client is in "Webauth" state so it looks like it's expecting something, but ISE says it's all ok and I can see the 3850 traffic going through the process flow.
If I attach an AP to the WLC directly and have the accounting box ticked, then it all works exactly as I'd expect - this is just, well, odd....

Cisco ISE - CWA AD Authentication

Hello,
I'm using a Cisco ISE on 1.3 and have a CWA portal setup for AD Auth. When a user connects to a particular SSID (from a WLC) that is setup for mac filtering, it redirects to a CWA via the Auth Policy. the CWA is disabled, they login, the device registers, etc.. and all is well. The next policy checks to see if the device is registered, and if so, bypasses the Auth. Which also works. However, any AD account can authenticate against the CWA, not the particular AD account I want. I don't know where to put the Auth Policy or what it looks like. Any help would be appreciated. I've tried a few combinations to no avail.
Below are my current Auth Policies, as I mention above. They work, but the CWA validates any AD credential, not the group I want. Should a NetworkAccess:UseCase=GuestFlow go between the 2 policies perhaps?

Hi Marc, what I meant by "desired_permissions" is what your environment/situation calls for. With that being said, returning back only "access_accept" with your "authorization profile" would work but at the same time it will give the authorized users/devices full access. So unless you have an ACL to Firewall off the guest users, you would need to return some additional attributes when trying to restrict/limit guest users/devices.
For instance, I like to use Policy Sets and dedicate a policy set per SSID and then either a general Policy Set for Wired or one Policy Set for Corporate Wired and one for Guest Wired. If you don't use policy sets, then you should create one "authorization rule for Guest_Wired and one for Guest_Wireless.
For the Guest_Wired, you will need to return "access_accept" and then a "DACL Name" that you can create locally in ISE.
For the Guest_Wireless, you will need to return "access_accept" and then a "Airspace ACL Name" That ACL is not a DACL (WLCs do not support DACLs). Instead, that is an ACL that you configure locally on the WLC, thus, the name must match on both ends and it is case sensitive!
Both the DACL and the "Airspace ACL" would contain rules that fit your environment/security requirements. Typically though you would have:
1. Permit DNS- Needed for DNS resolution
2. Permit access to ISE - Needed for the guest pages to properly load)
3. Deny any private/RFC 1918 addresses - Blocks guests from accessing internal hosts
4. Permit everything else - Needed for general internet browsing
I hope this helps!
Thank you for rating helpful posts!

Cisco ISE multiple EAP authentication methods question

With Cisco ISE can you have various clients each using different EAP methods, such as PEAP for Windows machines, MD5 for legacy and TLS for others?
My current efforts seem to fail as if a device gets a request from the ISE for an EAP method it doesnt understand it just times out.
Thanks in advance.

Multiple EAP Methods work fine. If your Clients are being crap you could try forcing then to use a specific set of Allowed Authentication Method by creating more specific Authentication rules.

Cisco ISE - line posture node and switch connection.

I am studying how Cisco ISE - Inline Posture Node working under the Bridge Mode. I learned that I need to configure the vlan mapping between the untrusted and trusted interfaces of IPN device ( http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_ipep_deploy.html - Figure 10-6).
Does that mean I can setup a 802.1Q trunk link between the switch port and trusted/untrusted interface on IPN? Is there any vlan mapping entry limitation? Thanks.

Cisco Auto Anchor Web Authentication - NAS IP Address

Hi,
I've setup auto anchor web authentication for my guest network. I want my Web Authentication requests to be authenticated by ISE however need the authenticating device to be the Anchor Controller.
I setup the WLAN to authenticate against ACS4.2 and it works correctly, the NAS IP address is the Anchor controller. When changing the WLAN to auth again my ISE 1.2 server, authentications are sourced from the foreign controller.
Has anyone come across this or know why ISE is seeing the NAS IP Address as the foreign wireless controller?
Thanks,

Cisco 5508 external web authentication

Hi all,
Firstly, I do apologise as this question has been posted in another forum, I believe it is the wrong one though hence me posting here.
I am running with a pair of Cisco 5508 controllers with 7.4.121.0 installed. We offer a guest Internet service to our user base and guests. To access the guest service a user must first authenticate via an externally hosted server, I won't go into the specifics but it is a secure service will a valid, signed cert for the login page. The issue I am hitting is that when a user logs into the portal the controller cert is then displayed (2.2.2.2) which returns a cert error. It kind of makes the service look insecure when it isn't. I've read numerous articles about creating CSRs, etc and loading certificates on the controller, but the issue we have is that we use externally hosted DNS servers for the service and they are refusing to create a DNS record. We can't use internally hosted DNS servers as this breaks our security policy. Is there any other way around this or do I just have to have the user accept the cert error?
Thanks

I hear you and I was under the same impression. If I go through the steps I followed maybe it can be explained..
Upgraded the primary controller from 6.0.x to 7.0.x a, APs upgraded. Upgraded FUS to 1.9. Upgraded controller to 7.4.121.0, upgraded APs. APs joined the controller. Disabled WebAuth Secure Web. Followed same steps for secondary controller. Shutdown primary controller to test failover to secondary. APs did not failover. Waited 15 mins, debugged CAPWAP and saw nothing coming in. Brought primary back online, waited 15 mins, debugged CAPWAP and saw nothing coming in. Waited a further 15 mins. Still no APs joining. Enabled WebAuth Secure on the primary, and boom, all the APs joined the primary. Not sure if this was just a coincidence, but this was the behaviour I witnessed. I'm running a pair of 5508's.
I've not witnessed this before, but this is the first time I've disabled this setting. Understand it has nothing to do with APs joining and may just be a coincidence, but this is what I experienced. I ran out of time during the change window so couldn't test this further and try to simulate again, will try again when the next window becomes available.

ISE wireless web authentication for guest management not redirecting

Hi forumers'
I face the problem that after connecting to the wireless guest network, it won't redirect me to the ISE guest portal . This happen on my iPhone. The iPhone is running on iOS 5.0.1
Whilst on workstation it's working well.
attach the snapshot of what happen on the iPhone.
Any clue to torubleshoot? Thanks
Noel

Hi
I still fail whilst i testing on my iPhone.
I'm not using ISE self-signed certificate, i create CSR and signed by root CA server. So once i try to connect it won't prompt me the "accept ceritficate"
My WLC local auth certificate verdor certificate is signed by the same root CA server as well.
So i test on desktop to run safari broswer, it able to redirect to ISE guest portal.
Can please suggest more troubleshooting guide?
Thanks
This is how the outcome for the safari broswer

Local web authentication fails

hello experts!!!
i'm having trouble making clients authenticate locally on a 2106 controller with ios v.4.1.171.0.
do i need a radius server to be able to do local auth.
also the auth login page does not appear automatically when i open a browser and type www.cisco.com or any other url.
i have to type in vip 1.1.1.1 to be able to bring up the login in page.
is this how it supposed to be for this particular code.
thanks for any input... really appreciate it.

tried the 0 timing but the guest will have unlimited time session like a legit user.
i wanted to set guest accounts, say guest1=1hour, guest2=2hours, guest3=3hours. and that these accounts should not be deleted automatically when their times expire. so the next time a guest comes to the office i can just choose guest1,2 or 3 account to allow him to use the internet.
also i notice that after creating the guest account, its timer starts and continues regardless whether i use the account or not. and eventually, deleted after it reached the time limit.
did i get through...
thanks-a-banks!!!

Cisco ISE - Not use FQDN in url-redirect parameter

Hi,
I am using Cisco ISE Central Web Authentication for Guest Wireless. Clients are redirected for web authentication to: https://ip:port/guestportal/gateway?sessionId=SessionIdValue&action=cwa as it is specified by the url-redirect parameter in the Authorization Profile.
The “ip” field in the url is now replaced by the FQDN of the Cisco ISE, but I want to use the IP address instead of the FQDN. Is there any way to do that?
As far as I know in version 1.2 you can use the “ip host/no ip host” command to indicate what you want to use in the URL. However my Cisco ISE is running version 1.1.1.268.
Thank you very much.
Joana.

Available in 1.2, and available as a "bit of a bodge" in 1.1.x (read "a lot of a bodge")
If you only have one PSN then you may be able to get it to work, but after that you lose the ability to get the session to be pointed automatically at whichever PSN they hit initially so it would break.
Copy the settings that are applied when you use CWA, then create your own based on the same settings but using the ip address pasted in there instead.

Cisco ISE 1.1.2.145 Admin Authentication using LDAP

I have configured the LDAP and able to retrive our LDAP directory structure. Now, I am trying to point the 'Admin Access' authentication to "External Identity" Source which is the new LDAP IS I created. But I couldn't find an option to authenticate locally if for any reason the LDAP configuration doesn't work. I learnt that ISE can automatically revert to local auth provided the External Idenitity sources are unreachable. How can I test the LDAP authentication with out breaking our Admin Access? I thought of opening two parallel sessions, one with Super Admin Local Account and the other with Domain account. But I noticed that ISE communication is smart enough to logoff/login any other sessions in different browsers so basically I can't open two parallel sessions from same machine to do the tests. Suggestions? or Am I missing something here?
Many thanks in advance.

Hi Srinivas,
Even if you set up LDAP as an External Identity source for admin access, you can still fallback to Internal without getting locked out. As per the ISE user guide :
During operation, Cisco ISE is designed to "fall back" and attempt to perform authentication from the internal identity database, if communication with the external identity store has not been established or if it fails. In addition, whenever an administrator for whom you have set up external authentication launches a browser and initiates a login session, the administrator still has the option to request authentication via the Cisco ISE local database by choosing "Internal" from the Identity Store drop-down selector in the login dialog.
http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_man_identities.html#wp1351543
Please refer to the attached screenshot from my lab ISE:
I have configured admin authentication against AD, but I still see both "Internal" and "AD" at the time of login.
Hope this helps.
Thanks,
Aastha

Cisco ISE authentication failed because client reject certificate

Hi Experts,
I am a newbie in ISE and having problem in my first step in authentication. Please help.
I am trying to deploy a standalone Cisco ISE 1.1.2 with WLC using 802.1x authentication. The user authentication configured to be checked to ISE's internal user database for early deployment. But when the user try to authenticate, they failed with error message in ISE :
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
I've generate a certificate for ISE using Windows Server CA and replace ISE's self-signed certificate with the new certificate but authentication still failed with the same error message. Must I generate a certificate for WLC also? Please help me in solving this problem.

Ratna

Multiple domains authentication on Cisco ISE

Hi,
Does the current Cisco ISE supports for authenticating on multiple Active Directories ?
I can only set Cisco ISE to join on single active directory and LDAP
Does anyone have set Cisco ISE to support EAP-FAST with WPAD or PAC provisioning ?
Thanks
Pongsatorn

Hi,
We are into a situation where we need to authenticate users of two domains and these two domains are completely independent (no common DNS server). ISE is not able to resolve one of the domain using the DNS server settings and Adding a host entry for the domain name is not sufficient since Kerberos, GC and LDAP SRVs need to be resolvable as well.
From what I know ISE 1.3 should supports disjointed domains and there is no requirement for ISE to have 2 way trust relationship with domains.
Please share your experience if someone has faced similar situation before.

Akhtar

Central web authentication

I have downloaded the new Cisco ISE, I've managed to configure 802.1x and MAB succesfully but I want to configure wired centralized web authentication, but I cannot find any documentation how to configure ISE and Cisco Catalyst (IOS) switches to use this feature (I only find (limited) documentation about local web auth on the switch).
I want to achieve the following authentication order on a switchport:
802.1x
MAB
central web authentication
So if a guest user comes with his laptop, 802.1x is not configured on his laptop and he's not in the Mac Bypass DB, he should "failover" to web auth and get the ISE guest portal webpage with his web browser. There he enters a guest username and password (which is of course already in the ISE DB) and he should get web access.
I've configured the switchport with the following commands
switchport access vlan 99
switchport mode access
switchport voice vlan 50
authentication event no-response action authorize vlan 32
authentication host-mode multi-domain
authentication order dot1x mab webauth
authentication port-control auto
authentication violation protect
authentication fallback webprofile
mab
dot1x pae authenticator
dot1x timeout quiet-period 2
dot1x timeout tx-period 2
spanning-tree portfast
spanning-tree bpduguard enable
the web-profile with access-list to permit DHCP traffic between the attached device and any DHCP server in the vlan 99, and communications with ISE (also in vlan 99) at the moment "fallback webprofile" is triggered (I don't know if this should be configured with central webauth?)
SW01T#sh fallback profile webprofile
Profile Name: webprofile
Description : webauth profile
IP Admission Rule : NONE
IP Access-Group IN: 133
FYI, the access list:
Extended IP access list 133
10 permit ip any host 10.175.0.29
30 permit udp any any eq bootps
40 permit udp any eq bootpc any
In the ISE, I configured DOT1x and MAB. In the MAB profile, I configured "continue" if user is unknown, and then an authorization profile for the web authentication:
(attributes of the profile):
Access Type = ACCESS_ACCEPT
cisco-av-pair = url-redirect-acl=webauth
cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionId=SessionIdValue&portal=https://10.175.0.29:8443/guestportal/gateway?sessionId=SessionIdValue&portal=http&action=cwa&action=cwa
But it doesn't work. If I attach a device, it tries 802.1x, it tries MAB, then it fails over to "web authentication" but immediately fails with "no-response" message:

Hi Tarik,
thank you for the fast reply.
I've configuried the extra settings you told me (although I thought the ip admission configuration was only for local web authentication (where the switch acts as a http server).
But it still doesn't work. The pc is getting the ip address from the dhcp server but if I open a browser session, I do not get redirected to the ISE portal in order to log me in with a Guest account.
If I look at the authentication session of the port, it looks like the ISE has correctly sent the redirect acl and redirect url to the switchport:
Switch# show auth sessions int fa 1/0/3
           Interface: FastEthernet1/0/3
         MAC Address: 0011.25d7.6c6c

       webauth Not run
As you can see, the "web authentication" is the result of a "succesful MAB". This is because I had to configure ISE to continue on MAB if the user was not found (I found that somewhere in documentation). Then I have configured a default authorization profile where the "web authentication" is triggered. This is where I've configured the redirect-url and so on and this is of course sent to the switch as a succesfull MAB:
authorization profile "webauthentication" with the "centralized web authentication" settings configured (see attributes output):
Access Type = ACCESS_ACCEPT
cisco-av-pair = url-redirect-acl=webauth
cisco-av-pair = url-redirect=https://ip:8443/guestportal/gateway?sessionId=SessionIdValue&action=cwa
Actually, I really have no idea if I have correctly configured ISE to handle central web authentication...
If I check the "show ip admission cache", nothing is seen in there.
