7921G and EAP-TLS

Has anyone been able to import certificates into the phone. I am attempting to install a user certificate that was generated using a CSR from the phone. We are using an ACS 4.0 which passes the cert off to a MS AD server for validation. Any guidance would be appreciated.

Yes should work fine. When creating the CSR, will need to upload the root cert for the CA that is signing cert. Then upload that signed cert that is in DER format.
Ensure you have created a user account for the common name that you have specified and ensure that CN comparison is enabled for EAP-TLS.

EAP-PEAP and EAP-TLS on same switched network

Hello,
I'd like to enable both EAP-PEAP and EAP-TLS on the same network to support 802.1x authentication. The reasons are because of historical things i.e. 'older' devices use PEAP and newer devices use TLS. Over time all will be using TLS, but for now both will the there.
The AAA server is a Cisco ASC (4.2 or 5.1 - don't know yet)
I've not tested this or so, but I don't think this will be an issue....because from a switch point of view, it is just passing EAP traffic to teh Radius and so the required services need to be made available on the Radius server...is that a correct assumption?
Thanks,
Guy

You are right Guy, the switch just as act as an termediary device. It just passes EAPOL packet between the ACS server and client, and waits till the ACS server authenticate the client(internal DB, or external DB= AD, LDAP). You just need to enable EAP/TLS, MS-CHAP and MS-CHAPv2 for PEAP in the ACS server. Last make sure that your certificates at both side are valid and sign by the CA.
Good Luck,

PEAP and EAP-TLS on ACU?

Hi,
Does Cisco have any plan to support PEAP and EAP-TLS in the next release version of ACU?
Thank you.

As far as I know, there is no such plan as of now.

ISE and EAP-TLS

Hi
We're planning on implementing eap-tls for our corporate iPads and in the past I've successfully tested it authenticating against ACS5.3 but now that we've moved to ISE (1.1.1.24) I'm getting an error.
22045 Identity policy result is configured for password based authentication methods but received certificate based authentication request
I've tried two different profiles, one with a certificates and AD credentials and the other one with just certificates but the error message is the same for both.
EAP-TLS is enabled in the 'Default Network Access' authentication result.
Can anyone shine a light on where I'm going wrong?
Thanks
Martin

Martin,
Then that makes sense, since the ISE uses certificate based authentication when using eap-tls the certificate doesnt have the OIDs to support certificate based authentication. Here is a guide that shows the requirements needed in order to authenticate clients via certificates:
http://support.microsoft.com/kb/814394
Here is the comment in the article in this case the IAS is the radius server and the same holds true for ISE:
The IAS or the VPN server computer certificate is configured with the Server Authentication purpose. The object identifier for Server Authentication is 1.3.6.1.5.5.7.3.1.
Here is the Cisco eap-tls deployment guide which references the same as above:

Cisco ISE - eap-peap and eap-tls

Hi,
Does anybody have an example of an ISE authentication policy where authentication requests coming from a WLC can be handled by TLS and PEAP?
I dont seem to get that working, I do however make the ISE application crash with my config which is not the idea.
If peap use this identity source, if tls use 'this certificate authentication profile'.
Thx

OK,
so I have just fired up my lab and I actually created an Identity Sequence which contained my AD & my certificate profile.
The authentication policy was allowing EAP-TLS & EAP-PEAP.
I then created 2 authorization rules, 1 for users and 1 for machines permitting access based on windows AD group.
What i found out was that the Windows 802.1x supplicant can only support 1 method of authentication, so if you want this to work properly, you need a different supplicant. I think Cisco do a more advanced one, not sure. You can then specifically choose that for machine auth you use EAP-TLS and for User Auth you use EAP-PEAP.
In my setup. Machine auth ONLY happens when the user logs off the machine and it is sitting at Ctrl+alt+del so that it can still talk to the network and get all relevant updates etc. I found that not only did the machine authenticate using EAP-PEAP, it also authenticated using TLS... I think that is because of the wireless settings I had. I chose EAP-PEAP for wireless settings
When the user then logs in, the user account authenticates using EAP-PEAP. I dont think you can authenticate both the logged on user and the machine at the same time. Not with the native windows supplicant anyway. Windows either sends authentication request for the user or the machine but not both.
Hope that helps.

ACS 4.2 and EAP-TLS with AD and prefix problem

Hi there
we have the following situation:
- 2 x ACS (1 x ACS SE 4.2 and 1 x ACS 4.2) for domain A
- 2 x ACS (1 x ACS SE 4.2 and 1 x ACS 4.2) for domain B
First of all, is it a problem to have an ACS SE and an ACS working together for one domain, I don't think so? When we had only one domain and both ACS SE were responsible for domain A, it worked.
Now after the changes, machine authentication with EAP-TLS doesn't work anymore. In the logs it always says that the "External DB user is unknown" for a (machine) username like host/abc.domain.ch
This is the normal output of the Remote Agent, it finds the host but then nothing happens:

It's clear that the test was not successful because of the wrong "machine password" but it's a different output as before. I saw that in ACS 4.1 you could change the prefix of /host to nothing, but in 4.2 this is not possible anymore.
Could this be the problem or does someone see any other problem?
Best Regards
Dominic

Hi Colin
thanks for your answer, we had the this setting correct. I was able to solve the problem yesterday, we had some faults in the AD mapping.
I didn't know that when I select more AD groups for one ACS group in one step, that the user / host has to be in every of these AD groups (AND conjunction).
Now I only added one AD group for my ACS group and it works. The error message "AD user restriction" was not very helpful for finding this fault ;-)

I have a large customer that is moving into a new building and adding some
new wireless.
They are using a 5508 with 1142's and an ACS server.
They will have the following SSID's
SSID01 -> WPA-EAP-TLS
SSID02 -> WPA2-EAP-TLS (future use)
SSID03 -> Guest Access (internet access only)
They currently use this design across the enterprise which has worked well.
The problem is to get certificates pushed down to the client for the EAP-TLS
they always connect the machine once by wire and log on to the domain so a
GPO pushes the cert to the machine.
This creates a problem that I don't know how to solve as they want to use
iPhones on the new deployment.
Does anyone have any ideas on how to get a cert down to the iPhones for use
with the SSID's?
Thanks in advance for any assistance.

I don't think we can push certs from windows server to iphones . Probably set up a webpage say a accessible from a different ssid from which clients can download and install cert. ?

ACS 3.3 for windows - Win AD and eap-tls problem

Hi,
I have a problem with an ACS to authenticate users with certificate on MS AD.
Working things:
PEAP authentication with the MS AD;
EAP-TLS authentication with the local DB.
Not working things:
EAP-TLS authentication with MS AD.
Because I'm able to auth users with PEAP on MS AD, I guess my config on MS AD is correct.
Because I'm able to auth users with certif in EAP-TLS, I guess my certif config is correct.
So, why it's not working with the combination EAP-TLS and MS AD.
I receive the error 'External DB Account Restriction'
Thanks for your help.

Hi,
This is what is interesting,
AuthenProcessResponse: process response for 'phd' against Windows Database
Unknown User 'phd' was not authenticated
Done RQ1027, client 50, status -2125
The field that is being picked from certificate has the value 'phd', check you check which field is it.
And was the logging at full?, I think something is missing in the logs.
Lets do a sanity check, and go through following link again,

Rras, nps and eap-tls

Good day!
We're trying to deploy VPN schema using RRAS (2008R2SP1, l2tp), NPS and certificates as user authentication method
RRAS server short name is RRAS. it is in domain (AD, domain.local)
But we must use local (on RRAS) SAM database (not domain users) as user database
We've change defaultdomain registry key to "RRAS" as shown in technet article (https://technet.microsoft.com/en-us/library/dd197452(v=ws.10).aspx)
In NPS we've setup connection and network rules (nothing special, by default, only smartcard as eap auth method)
In local SAM there is test user "user1"
In test certificate in UPN we wrote "user1"
But we have next error - Authentication failed due to a user credentials mismatch
In windows security log we can see:
User:
Security ID: RRAS\user1
Account Name: user1
Account Domain: RRAS
Fully Qualified Account Name: RRAS\user1
It looks correct, isn't it?
Also we tried UPN=rras\user1 - the same result
When we use AD as user DB and UPN=[email protected] - it works correctly
What we do wrong?
Can we use non-domain usernames as UPN in certificates?
How to map in certificate non-domain user?
Thanks!

Eve,
yes, the registry key DefaultDomain is configured to RRAS (name of VPN server)
detailed information was in first message
VPN architecture consist of one server (RRAS and NPS role installed)
On NPS we chose EAP auhentication method with smartcard or other certificate type only
clients connect to RRAS using michine and user certificates
IKE phase is compleated successfully
But on user authentication phase described error is generated
I repeat main questions:
1. Can we use non-domain usernames
as UPN in certificates?
2. How to map non-domain user
in certificate?
Thanks!

Access connections 5.50 and EAP TLS with Computer certificate

Hello,
I'm trying to connect to a Wifi using Computer certificate to authenticate and it works perfectly fine with windows Wireless Zero Config however with Thinkvantage Access Connection I always get an authentication error.
I'm using a R61 with a ThinkPad 802.11a/b/g/n, 802.11b/g/n Wireless LAN Mini PCI Express Adapter. It's been updated to the latest driver (v7.6.1.260b)
OS is windows XP with SP3 and all the windows update (as of today).
On my Radius server this is what I get:
If I use WZC I get this in the authentication:
Security ID: DOMAIN\R61WXP$ (this is my computer name)
Account name: host/R61WXP.domain.local
Account Domain: DOMAIN
FQDN: DOMAIN\R61WXP$
When I use Access Connections:
Security ID: DOMAIN\Guest
Account name:
Account Domain: DOMAIN
FQDN: DOMAIN\Guest
My Access connection profile is set this way:
IEEE802.1x => Authenticate as Computer when the information is available.
I hope someone can help !
Thanks!

Hi,
try to dissable the IEEE802.1x => Authenticate as Computer when the information is available.
Make also sure, that the profile connection is correctly configured in the AC profile settings.
This mighe the the root cause.
I can tell you, that there must be something missconfigured, as this configuration will surelly work .
Cheers

EAP-TLS with ISE 1.1.2 and WLC 7.0.228

Hi,
I'm on process of implement Cisco ISE with Wireless LAN Controller. According to my post, I would like to know that if Supplicant Provisioning and EAP-TLS does support on this type of firmware code.
WLC running on 7.0.228 since most of production APs are 1230
ISE running on the latest version.
I have to use EAP-TLS and Supplicant Provisioning on these platforms.
Is this possible to do about this ?
Thanks,

Authentication eap-tls on ACS or local EAP WLC over Lwapp and 7921

Hi All,
I install WLC to provide Wlan architecture and the project was extended for VoWLAN. we have 7921 and E51 running over the wide WLAN architecture.
Computer using Data over wirless are working over PEAP done by ACS and CA signed certificate + user secret on PC is link to the domain account and secret stay the login and password. Our problem is that user and password is link via ACS to Active Directory. The policy of password is to change frequently.
For the Phone we are actually running authentication over Leap but I'm working to define the best security solution for us.
I confront PEAP and Eap-TLS for now:
1) PEAP check the authentication of ACS via certificate trust and authenticate via MS-Chapv2 and the secret password known by user. My problem here is the phone can only be static what is potentially not acceptable
2) Eap-tls which is the best secured security due to the double side certificate authentication + (login / password) on the phone
so I need to manage here Certificate Management ? I mean I can use either the MIC CA certificate on the phone or User CA defined one which I can put on ACS or Local EAP WLC and the put the ACS CA trust on the Phone.
If I understood well I have to put User.cer and ACS_CA.cer on each phone and pout the User_CA on the ACS ?
I have already Certificate on the ACS signed by CA (like veri-signed) so I must create CSR for any phones to be able to use the same CA ?
I'm thinking to use also the local Eap certificate of Controller to manage all of that to avoid every potential money to pay to the trust CA of ACS
can you help me to know if I understood everything good ? I would be please to exchange experience on that
thanks ;)

I am currently using EAP-TLS authentication on my wireless users using ACS 3.2. I have had that problem before. This is what I did...
Setup a Microsoft Certificate server as my
CA. You can use same machine wih your ACS and CA.
Then, generate certificate signing request from ACS then request a server certificate from CA then copy and install a certificate to ACS. On the ACS, go to global authentication setup check the EAP-TLS cetificate. If it failed to respond means that the server certificate is not properly setup.
On the windows xp clients, connect your machine using wired LAN, then request a certificate from CA(the same CA that you have use to your ACS) using IE (ex. http://CAip/certsrv), but this time request a client certificate. The name you should put when requesting the cert must be you local windows user, use 1024, choose microsoft base cryptographic provider 1.0. then installl the certificate on the client. Verify you client certificate it i was installed properly.
At that poit you should be able to connect you r wireless client using EAP-TLS.

EAP-TLS wi-fi net for PC and iPhone

Hi, everyone! I'm rather confused and hoped that someone could help me to make the situation clear.
We wan't to establish a wi-fi net with WPA-2 Enterprise and EAP-TLS for computers and mobile devices (iPhones, Nokia Symbian, Android devices).
The connection is organised in such way: client---AP 1240---ACS 4.2---AD(server 2003)
I have 2 testing computers with wi-fi adapters: one is connected to the domain (has a wire connection), another has a local account, and an iPhone. I customized the settings on these computers,iphone, AP and ACS.
We have our own CA, 2-tier PKI infrastructure. I have installed the ACS and client's certificates on all the devices (by the way, they are 2048 bit size of).
I manage to connect from a computer included in the domain but the second PC and iPhone refuse to connect,respectively:
"EAP-TLS or PEAP authentication failed during SSL handshake".
"EAP-TLS or PEAP authentication failed due to unknown CA certificate during SSL handshake"
Also I saw in logs that "Machine authentication is not permitted" so the domain PC authenticates through user account and is mapped to a special group.
So I think the reason is that only domain devices are allowed to join the net. How can I change this thing?
Another variant is that I issue the certificates first to wired domain computers and then export them to non-connected to domain devices so they have inappropriate credentials.
Please, if you have any thoughts about the reason of the problem, share them. I would appreciate any help.

The ATV is strictly a wifi client, it doesn't function as a router or access point. You can connect it to your router either by wifi or Ethernet cable. Your pc doesn't need a wifi card to work with an ATV as long as they're both on the same network.

FlexConnect, EAP-TLS and dynamic VLAN assignments

I need to integrate Cisco ISE and WLC5508 with FlexConnect (local switching) using EAP-TLS security for wireless clients across multiple floors (dynamic VLAN assignments based on floor level). The AP model used is 3602.
I have some questions:
- What RADIUS Attribute can be used for dynamic VLAN assignments based on floor level? Is there an option where I can group all LWAPs in same floor for getting certain VLAN from ISE?
- I intend to use WLC software version 7.2 since 7.3 is latest version. Has someone use WLC software version 7.3 without any major bugs/issues pertaining to FlexConnect and EAP-TLS?
- I read some documents saying L3 roaminig is where the associated WLC has changed. However if user move to different subnet but still associated to the same WLC, would this be consider as L3 roaming too?
Can someone assist to clear my confusion here? any reference url for layer 2 and layer 3 roaming details is appreciated. Thanks

I'll give this a shot:)
For radius vlan attributes, bothe ACS and ISE in the policies have the ability to just enter the vlan id in the profile. You can either do that or use the IETF attributes.
The RADIUS attributes to configure for VLAN assignment are IETF RADIUS attributes 64, 65, and 81, which control VLAN assignment of users and groups. See RFC 2868 for more information.
64 (Tunnel-Type) should be set to VLAN (Integer = 13)
65 (Tunnel-Medium-Type) should be set to 802 (Integer = 6)
81 (Tunnel-Private-Group-ID) should be set to the VLAN number. This can also be set to VLAN name if using a Cisco IOS device (excludes Aironet and Wireless Controllers however).
You can find this by searching on Google.... A lot of examples out there
v7.2 and v7.3 I have had no issues with, with any type of encryption used. With 7.0 and 7.2, I would use the latest due to the Windows 8 fix.
Layer 3 roaming is what's going to happen if the AP's are in local mode. This means that the client will keep their IP address no matter what ap they are connected to and or WLC as long as the mobility group is the same. So a user who boots up in floor 1 will keep its IP address even if he or she roams to the 12th floor and as long as he or she didn't loose wireless connection.
FlexConnect you can do that. The AP's are trunked and need to have the vlans. So what your trying to do will be disruptive to clients. When the roam to another floor ap that is FlexConnect locally switched, they will drop and have to re-associate in order to get a new IP address.
Hope this helps.

EAP-TLS and EAP-PEAP Clients

Hi guys
I have installed a dot.1x solution for a customer using ISE. The ip phones have certificate from CUCM server. In the ISE a wired-dot.1x with eqp-tls enabled policy is configured so that when ip phones or PC connect to network they get authenticated using EAP -TLS. I have required certificates imported on pc's and ISE server. That part works absolutely fine.
Now I have been asked to configure EAP-PEAP for video end points which doesn't support EAP -TLS.
The endpoints are configured with a username and password. The credentials are created in ISE server.
I create a second policy for wired dot.1x with EAP - PEAP enabled
The problem I am hitting is that if the PCM and phone policy is on top. The phone and pc gets authenticated. But video endpoint doesn't. I get authentication error messages saying certificate expected but received credentials.
When I move the video end point authentication rule above the pc and phones. The video end points get authenticated successfully. But PC and phone authentication breaks. The error message I receive is saying usrname and password expected but received a certificated based authentication.
Has anyone seen this type of scenario ? Any idea how to make EAP -PEAP and EAP TLS authentication work together ?
Thanks in advance.

Hi,
There are two ways you can tackle this with ISE, I will start with the easiest one and then the other one to cover your options.
You need to create an identity store sequence. This allows you to mix both certificate based and password based authentications, keep in mind that you can only map one Certificate authentication Profile in when using identity store sequences. More informations about configuring this is provided below:
http://www.cisco.com/en/US/docs/security/ise/1.1/user_guide/ise_man_id_stores.html#wp1117203
The next option would be to use the authentication policy configuration to map the patterns of the username (if common with your video endpoints), to forward their requests to the internal identity store. You can use regex to make this work and you can check for the radius username attribute.
Thanks,
Tarik Admani
