PEAP Windows Logon -Machine & User Authentication -Multiple VLANS

Windows Client <==> Access Point <==> Radius <==> Windows DC/AD
Windows OS : XP Client SP 2
Supplicant : Built-in Wireless Supplicant
Authentication : 802.1x PEAP(MS-Chapv2)
Access Point : Aironet 1200
Radius : ACS 3.3
Adaptors : Built-in
CA : Microsoft
I have a single SSID and am using a RADIUS server to assign users to different VLANs. When a computer boots up, machine authentication is used and the ACS tells the access point which VLAN to be on (i.e. VLAN1 192.168.1.x). Then when the user logs on the ACS tells the access point to switch the computer to a different VLAN (i.e. VLAN2 192.168.2.x). The problem is that the windows logon scripts do not run. Once the computer finishes booting, I quickly check its IP address and it still thinks it is on 192.168.1.x (VLAN1) when it is actually on VLAN2 and needs a 192.168.2.x address. If I give the machine time, it will eventually switch its IP to the 192.168.2.x address.
Has anyone else run across this? I assume that there is no fix and that it is a Microsoft problem. Obviously, it can't do the logon script if it does not have a valid IP for its VLAN. I also never know who will be logging into the computer to put the computer in the correct VLAN ahead of time.
Note: If the machine and user are both set to use the same VLAN, the computer does not have to switch IPs and the windows logon script works fine.
Thanks

Hi there.
I've tried that solution, and I had a similar problem. My problem was on the DHCP server side: there was a superscope defined with the different scopes for each VLAN. When I'd the MAC Address from one machine registered at the DHCP database, the settings were always the same. Then I deleted the superscope and only defined scopes for each VLAN. It's working fine now.
Hope this helps you.
Regards,
João

Cisco ISE - EAP-TLS - Machine / User Authentication - Multiple Certificate Authentication Profiles (CAP)

Hello,
I'm trying to do machine and user authentication using EAP-TLS and digital certificates. Machines have certificates where the Principal Username is SAN:DNS, user certificates (smartcards) use SAN:Other Name as the Principal Username.
In ISE, I can define multiple Certificate Authentication Profiles (CAP). For example CAP1 (Machine) - SAN:DNS, CAP2 (User) - SAN:Other Name
Problem is how do you specify ISE to check both in the Authentication Policy? The Identity Store Sequence only accepts one CAP, so if I created an authentication policy for Dot1x to check CAP1 -> AD -> Internal, it will match the machine cert, but fail on user cert.
Any way to resolve this?
Thanks,
Steve

You need to use the AnyConnect NAM supplicant on your windows machines, and use the feature called eap-chaining for that, windows own supplicant won't work.
an example (uses user/pass though, but same concept)

ISE - Machine + user authentication

I've searched forum, community but I couldn't find exactly what I need:
I have a client that want's to use two step authentication on wireless: first machine authentication to make sure that device is on the domain and then username/password authentication.
Now, I've read about MAR, EAP chaining, and I understood it all, only thing I didn't understand is:
If I configure ISE to authenticate machine, it will allow limited access to DC (for example).
Then, after that AuthZ profile is applied, what will do new authorization? My understanding is once MAR is done, AuthZ profileis applied and authorization is finished.
Now, I am not asking about turning on laptop, getting PC on the network, then logging in and then providing the user/credentials, etc. I am asking for this scenario:
How ISE policy and AuthZ profile should look like, for example, I come in the office, my wireless card is disabled, I login to my laptop, then I notice that my wireless card is disabled and now I enable it. I need to have Machine authentciation happening at that point + prompting user for username/password to complete registration on wireless.
NAM is already refused by client, so I need something that will work on plain Windows 7.
Thanks.

Hello Align-
In your post you are referring to two completely separate and independent solutions:
1. MAR
2. EAP-Chaining
MAR only happens when the machine first boots up and the host presents its machine domain credentials. Then the machine MAC address is saved in ISE. The MAC is preserved in ISE as long as configured in the machine timer. Keep in mind that if let's say a computer was booted while connected on the wired network, only that MAC address will be authenticated. If the user moves to wireless, the connection will be denied as ISE will not have any records of the wireless MAC. Along with all of that, you will need another method (usually PEAP) to perform the user authentication. Usually this method is not a very good one to implement due to the issues listed
EAP-Chaining on the other hand utilizes EAP-FAST and it s a multi-phase method during which both machine and user information is passed in a secured TLS tunnel. For that you need to implement Cisco AnyConnect as it is the only software supplicant that supports it at the moment. For more info you might wanna look into Cisco's TrustSec guide:
http://www.cisco.com/en/US/solutions/collateral/ns340/ns414/ns742/ns744/docs/howto_80_eapchaining_deployment.pdf

802.1x eap-tls machine + user authentication (wired)

Hi everybody,
right now we try to authenticate the machines and users which are plugged to our switches over 802.1X eap-tls. Works just fine with windows.
You plug a windows laptop to a switchport and machine authenticates over eap-tls with computer certificate. Now the user logsin and our RADIUS (Cisco ACS) authenticates the user as well, with the user certificate. After eap-tls user-authentication the RADIUS checks if the workstation on which the user is currently logged in is authenticated as well. If yes = success, if no the switchport will not allow any traffic.
Now we have to implement the same befaviour on our MacBooks Pro. Here the problems start. First of all I installed user and computer certificates issued by our CA (Win 2008 R2). So far so good. Now I have no idea how to implement the same chain of authentication. I was reading countless blogs, discussions, documentations etc. about how to create .mobileconfig profiles. Right now im able to authenticate the machine, and _only_ if I login. As soon as I logout eap-tls stops to work. It seems that loginwindow does not know how to authenticate.
1) how do I tell Mavericks to authenticate with computer certificate while no user is loged in ? already tried profiles with
<key>SetupModes</key>
<array>
    <string>System</string>
    <string>Loginwindow</string>
</array>
<key>PayloadScope</key>
    <string>System</string>
but it does not work
2) How do I tell Mavericks to reauthenticate with user certificate when user logs in ?
Thanks

Unfortunatelly this documents do not describe how to do what I want.
I already have an working 802.1x. But the mac only authenticates when the user is loged in. I have to say that even this does not work like it should. If Im loged in sometimes i need to click on "Connect" under networksettings and sometimes it connects just automatically. Thats really strange.
I set the eapolclient to debugging mode and see following in /var/log/system.log when I logout.
Feb 20 18:39:09 MacBook-Pro.local eapolclient[734]: [eaptls_plugin.c:189] eaptls_start(): failed to find client cert/identity, paramErr (-50)

Feb 20 18:39:22 MacBook-Pro.local eapolclient[734]: en0 EAP-TLS: authentication failed with status 1001
this are only debugging messages I get. Looks to me like eapolclient is not able to find a certificate (?)
The certificates are in my System keychain.
Unfortunatelly apple also changed the loging behaviour of eapolclient, I dont see any eapolclient.*.log under /var/log
Any ideas ?

Windows 7 Wireless Logon - Problems with 802.1X Machine & User Authentication

Hello All,
We’ve had difficulty with our Windows 7 clients authenticating to our wireless network. I’m hoping someone out there has experienced the same thing and can offer some help.
Some info about our environment:
Single Windows 2008 R2 domain with 6 DCs
MS Radius server
Aruba wireless controllers
The Problem:
The client computer boots,
Auths as machine (802.1X successful)
User enters creds
User auth (802.1X successful)
To this point, everything is working normally. Next is where it gets weird.
During the logon process, there is another machine auth
2-5 minutes later another User auth
OS is up and usable (connected to wireless network); however, no homefolder is mapped and GPP didn’t apply properly.
From what I understand, after the user has logged in, Windows never attempts another machine authentication. When the user logs out, Windows can attempt it.
Can anyone offer some insight to what is causing this? I have logs available if anyone is interested.
Thanks in advance for any help you can offer!
Brett
-- Brett

I did a network trace to gain more insight. I don’t understand why after 802.1X auth is successful on port 1, it then initiates 802.1X auth on port 2.
Can you offer any insight?

How to avoid User Authentication Multiple times after run the Bo report

Dear Experts,
I am facing issue in BOBJ portal. we are trying to run report in portal and its working fine and running ME23N transaction from that report.
Once we click on ME23N transacation from that report its opening new pop up window and data showing perfectly .
But after close that pop up window and go back BO or BI TAB in portal its asking uid and password.
But first time it's not asking. If I log out and login again then it will work but after run and close the pop up window and come back to BI or BO tab again is asking user ID and Password.
I checked all Log on tickets and validity period and system connections every thing fine.
Could you please Help me ...

Windows 8.1 user with multiple external drives. Lightroom CC 2015 freezes on import. Need to have Lightroom recognize only a single drive.

I see that Adobe still hasn't fixed this issue where Lightroom freezes up during import when a system has multiple external drives attached. Disappointing.
A friend suggested that I configure Lightroom to only recognize the single external drive where I save my RAW files. I haven't been able to find out where in Lightroom's settings to do this.
Currently the only folders I have in Lightroom are my local C disk and my external drive with the RAW files, (K), where I do all my editing.
Can anyone offer advice on how I can either do what my friend suggested or find another way of dealing with/solving this issue? Currently Lightroom is almost unusable for me since I cannot add new files on my K drive to develop.
Thanks.

I save edited images from Photoshop into a new folder on the same hard drive my catalog is on, then attempt to import, or to right-click on the edited image and choose Open in Lightroom. Lightroom hangs in either situation.

Problems with 802.1x MS PEAP machine and user authentication

Using Microsoft PEAP 802.1x client on Windows XP SP2, if we enable machine authentication against a Windows Domain, the machine authentication is successful and the machine gets access to the network. However, when user logon occurs to the domain, contrary to the flow given in ACS and Windows documentation, no user authentication takes place.
We need to differentiate user access based on their identities. We need machine authentication only to allow users access to the domain controller and also GP implementation.
Any idea why user does not get prompted when they logon. 802.1x is configured in users profile and I have tried with both integrated and non-integrated with Domain logon (i.e. "use my windows logon name and password and domain (if any) option"
There is no record of any identity request/response in ACS after the initial machine authentication (which appears in successful authentication log)
We are using MS-CHAPv2.

Update...The problem of cached credentials in MS PEAP does not occur if "enable logon using Windows username and password (and domain if any) is checked. Using this option, MS PEAP always uses logged on users most current credentials.
However, using this option sends the username as "DOMAIN\USERNAME". Since we are using ACS internal database for user authentication (even though the ACS and Windows passwords are same - using an identity management system) ACS does not recognize the user.
I have tried proxy distribution with prefix stripping but it does not seem to work when it is pointing to the same ACS server on which proxy distribution is configured and which receives the request.
Any idea how the domain\ can be ignored by ACS?

Machine Authentication and User Authentication with ACS v5.1... how?

Hi!
I'm having trouble setting up Machine Authentication and User Authentication on ACS v5.1 using WinXP SP3 (or SP2) as supplicant.
This is the goal:
On wireless (preferably on wired too) networks, get the WinXP to machine authenticate against AD using certificates so the machine is possible to reach via for example ping, and it can also get GPO Updates.
Then, when the user actually logs in, I need User Authentication, so we can run startup scripts, map the Home Directory and so on.
I have set up a Windows Sertificate server, and the client (WinXP) are recieving both machine and user certificates just fine.
I have also managed to set up so Machine Authenticaton works, by setting up a policy rule that checks on certificate only:
"Certificate Dictionary:Common Name contains .admin.testdomain.lan"
But to achieve that, I had to set EAP Type in WinXP to Smart Card or other Certificate, and then no PEAP authentication occurs, which I assume I need for User Authentication? Or is that possible by using Certificates too?
I just don't know how to do this, so is there a detailed guide out there for this? I would assume that this is something that all administrators using wireless and WinXP would like to achieve.
Thank you.

Hello again.
I found out how to do this now..
What I needed to do was to add a new Certificate Authentication Profile that checks against Subject Alternative Name, because that was the only thing I could find that was the same in both user certificate and machine certificate.
After adding that profile to the Identity Store Sequences, and making tthe appropriate rule in the policy, it works.
You must also remember to change the AuthMode option in Windows XP Registry to "1".
What I really wanted to do was to use the "Was Machine Authenticated" condition in the policies, but I have never gotten that conditon to work, unfortunately.
That would have plugged a few security holes for me.

Problem with Windows 7 802.1x prompted for authentication multiple times

I have setup a WLAN for users to bring in their own devices (devices are not on the domain). It is setup for WPA2-Enterprise/AES and it doesn't require certificates. We authenticate with a Cisco Secure Access Server 5.1.44 (setup with Active Directory).
I have configure dthe Windows 7 wireless client:
WPA-Enterprise/AES
PEAP - removed "Validate server certificate"
EAPMSCHAPv2 properties disabled "Automatically use my Windows login name and password
Advanced settings 802.1x - ticked for "user authentication"
My problem is when I connect to the WLAN, I'm prompted for authentication multiple times (x2). On the second login prompt everything logs in OK. No errors are received after the first login attempt.
Thanks

This doesn't have anything to do with eap settings?
Are the current defaults the recommended settings:
EAP-Identity-Request Timeout (seconds)........... 30
EAP-Identity-Request Max Retries................. 2
EAP Key-Index for Dynamic WEP.................... 0
EAP Max-Login Ignore Identity Response........... enable
EAP-Request Timeout (seconds).................... 30
EAP-Request Max Retries.......................... 2
EAPOL-Key Timeout (milliseconds)................. 1000
EAPOL-Key Max Retries............................ 2
EAP-Broadcast Key Interval....................... 3600
I have seen this multiple times on varying drivers and systems. The first time you login until it is cached.
Thanks,
Andrew

How to capture the Windows logon user

Hi. How I can to capture the Windows logon user for the browser.
I have a procedure on webtoolkit, and when I call the proc I pass the user of application, I need check if the net user is the same.

if you have to take the user name of the server machine it is just
System.getProperty("user.name");if you want to retrive the username from the client machine

SAP User Authentication via Windows Active Directory

The non-profit company I work for as an SAP Security Admin has been using SAP since 1999. We are currently running ECC 6.0, BI 7.0, and CRM 7.0. With fewer than 300 SAP users, we have not implemented CUA, so each of our multiple clients in these systems is managed independently.
The company recently licensed and implemented some non-SAP software to be used by all of our employees (~1200) in keeping track of & catagorizing their work time; a very handy feature of this software is that it depends upon Windows Active Directory for user authentication. Therefore, each employee logs into this time-keeping package by entering his/her standard PC userID & password. If you can log onto your PC, you can log into the time-keeping software.
That got me thinking & researching, because our SAP users - especially those who have access to three or more SAP clients - must maintain their passwords independently in each SAP client that they hope to access in the future. I'm certainly not the first person who has thought of how nice it would be to permit SAP users to log into all SAP clients across the landscape in which they have defined userIDs, using the same password that they are using to log into their PCs (i.e., the password that is stored & maintained in Windows Active Directory). My quest has led me to find presentations on this topic that typically involve modules we aren't using & very complicated configurations that we really lack the time & resources to employ; or, to third-party solution providers who claim to be certified SAP partners who would love to sell us more software to provide this convenience, usually irelated to single sign-on, LDAP, etc. The lowest pricing tier for such software usually would cover many times the number of SAP users we have to serve here - and it feels like trying to push in a tack using a sledgehammer. It is true that we have not used the same userID for our PCs that we have defined in SAP, so there would need to be some way to translate from one to the other, but our PC password rules are consistent with those we have configured in SAP clients, so it seems to me it should be very simple. Can anyone lead me to a more straightforward solution? If not, can you articulate why this has to be so complicated using SAP software when it seems so simple using relatively inexpensive timekeeping sotware?

Once installed, yes. This is all you need to maintain when users are added. You can even use LDAP if you like to sync all user info between SAP and MS AD domain, but this cannot sync the password, so using SNC authentication instead of using SAP passwords is ideal.

Yes, that is correct. The mapping is maintained using standard SAP user management, such as su01. The user in AD domain might have long account name, e.g. "firstname.verylonglastname" which is too big for use as a SAP username so you can map this long AD account name onto a SAP user called FIRSTLAST in one or more SAP clients.

Machine and User authentication with ISE 1.2.1

Hi ,
Can any one tell me in machine authentication what access need to be enable DACL for machine logon?
Can we enable the access on port level ? direct to tcp/udp or ip level what is the best practice.
Thanks
Pranav

is this what you are looking for EAP Chaining which uses a machine certificate or a machine username / password locked to the device through the Microsoft domain enrollment process. When the device boots, it is authenticated to the network using 802.1X. When the user logs onto the device, the session information from the machine authentication and the user credentials are sent up to the network as part of the same user authentication. The combination of the two indicates that the device belongs to the corporation and the user is an employee.

802.1x machine vs user authentication

In the process of depolying 802.1x on wired LAN. What is the difference between machine authentication and user authentication? Thanks in advance.

OK, so assuming we're still talking the MSFT supplicant, you have some options:
1) USe EAP-TLS and mark any certs deployed to your corporate-owned assets and non-exportable. This solves the issue by brute force. You don't exactly need machine-authentication to do this. You may need machine-auth for other reasons (as I believe we've discussed here).
2) If PEAP is in use, use the machine-auth and the Machine-Access-Restriction feature in ACS. What this does is a coupling of the notions of machine-auth as a preceeding policy decision for user-auth. Example: It is technically possible that anyone with a valid NT account may be able to 802.1x-authenticate from "any" machine. But with the machine-access-restriction feature, they will only be able to do so if ACS has also authenticated a valid machine-auth session prior to the login attempt.
3) Use a NAR in ACS. A NAR is a Network Access Restriction. If for example, you have a database of all the MAC Addresses you have (or an OID wildcard) you can configure further checking of a MAC address from an otherwise valid 802.1x authentication attempt. This effectively tells ACS to only allow authentication attempts from MAC Addresses it knows about.
Hope this helps.

Machine +User Auth for windows endpoint autheticating through ISE

Hi
Is there any way to use machine + user auth at same time when authenticating Windows machine through ISE. In Windows native supplicant there is option as
1) Machine OR user Auth
2) User Authentication
3) Machine Authentication
4) Guest authentication
I want to give more priveledge access to endpoints where they are joined to AD domain AND the user is logged in using AD credentials.
Is there any way to achieve this functionality ...

With windows you do not have the option, however with ISE 1.1.1 and the latest cisco anyconnect nam supplicant (which is free) has a feature called eap chaining, it uses eap-fast to send the authentication sequence just as you want.
Here is the reference:
