ACS + Wired dot1x machine authentication

• ACS, WCS, PEAP, Machine Authentication

  We are building a new wireless network with a new unit of ACS 5.2 and new controllers LAN with WCS.  We want to create a SSID encrypted/secure ONLY the machines managed by our care who can access the LAN with.  We are looking for the best solution with a minimum of complexity.  After that several internal discussions, we seek to use authentication PEAP (testing with a self-signed certificate), and then create a strategy to access the ACS to validate the machine is a member of Active Directory.  Unfortunately I can't find the way to validate membership of the machine.  I don't know if I'm missing something or if this is even possible.  If anyone has any suggestions for that to happen, or a better way to handle this, I would appreciate the help.

  What you need is the authentication of the computer. The machine will first authenticate with its letters of nobility (AD account) and then the user authenticates too. This option is available in the windows client.

  Then, you can also set the ACS to only allow a user to authenticate if the machien was authenticated before.

  You must enable auth on the ACS server machine (users and identity stores--> external Identiry stores--> Active Directory, check the box to turn on computer authentication)?

  Also - under Access--> Access Services policies, tab protocols allowed, you enable the option "host Lookup process.

  Create an access policy, activate the search for PEAP-MSCHAPv2/process host, set the conditions by using the identity group and has been authenticated Machine that looks like:

  (1) if Identitty group to the computer group, then allow access

  (2) if Identtity group to the Group of users and the Machine has been authenticated, then allow access

  (3) deny access by default

• Dot1x question: authentication MAB will never be failure or timeout

  Hello

  I have a problem when the switch will try to authenticate a device with MAB and it will never, or timeout.

  Here's the situation: where a device has 802 authentication. 1 x active but not a invalid parameters (or missing certificate).

  The switch will start dot1x for the customer and it will not be (a). He will switch to dot1x to MAB and... silence.

  I use a WS-C2960-24LT-L with IOS 15.0 (2) SE.

  Config:

  You can see above that is still running MAB but this device is not listed on the local store ID sequence or any where. If I run the command 'No mab', the switch will respond will be unavailable methods more and nothing more.

  However, when I remove the command MAB; reset the port; He eventually fail to dot1x and move to restricted VLAN.

  It is this value by default design or the drop between the switch and the ACS authentication? Should I just use MAB where it is needed?

  Thank you in advance.

  On your configuration of the interface, I normally expect to see flex active thus auth:

• dot1x EAP authenticator

  I have 3 ws-c3750-48ps in a pile and I would enable dot1x on battery, I entered the command:

  control-dot1x system-auth

  Group AAA authorization network default RADIUS

  Group AAA dot1x default authentication RADIUS

  I also enabled on the interface of multiple switches 2nd and 3rd in the stack with these commands to dot1x

  dot1x EAP authenticator

  Auto control of the port of authentication

  dot1x works successfully on these ports and I see the logs into acs, heres where the problem comes when I try to enable dot1x using the above commands on any interface on the first switch in the battery it does not work is as the switch does not support the dot1x. I don't get orders to dot1x in context sensitive help.

  I think it has something to do with the version numbers of the switch

  Switch 1 is v03

  Switch 2 is v08

  Switch 3 is v06

  I guess that there is a bug in version 3, but after googling I came not with ideas a lot, everything?

  You must add a command under
  Interface fa 1/0/6
  Access mode Switcport

  After this attempt to enable dot1x on this interface.

• Cisco ACS 5.1 Machine Auth problem

  Hi all

  I have a question about ACS 5.1 using EAP-PEAP (auth more user computer name and password). I managed configuration AD authentication with user credentials and auth of Machine and it works well for users and wireless peripheral companies.

  My rules ACS machine auth against computers AD that gives a positive/pass, then a rule against the user but check if unit is a unit of area valid with "has been authenticated machine = TRUE".

  The problem is when you use a Windows 7 device (laptop) and connect you using the local administrator account, I connect successfully to the network but the local Admin account is not in the AD. By default wireless adapter the W7 under Security > advanced settings > specify the authentication mode is only computer authentication.

  Does not send the client of W7 on credentials of the user?

  Has anyone encountered this problem before? Do I need to tweek client W7 via GP or is there a way to stop all machine authentication with a valid user name and password?

  Really appreciate all the responses and I thank you in advance.

• ACS with AD-with authentication of twins

  Hi gurus

  I want to integrate my 5.1 ACS with AD, my request is to check first for the machine authentication. If the machine authentication passes the customer name to username/password must be validated and customer should be in VLAN X. If the computer authentication fails, the user/password customer name must be validated. If authentication is successful the customer should be put into VLAN Y

  Let me know if this is possible

  Thank you

  NikhiL

  Nikhil,

  You can set a condition in your authorization policy and check whether the machine authentication has been made and your result out of this basic requirement.

  Here's a guide that corresponds to your questions:

• With Cisco Secure ACS for Windows GANYMEDE +, authentication fails with AD

  I'll put up a Cisco Secure ACS 4.2 server to act as a RADIUS server for switches and routers I use Windows 2003 server for the candidate countries.
  and an Active Directory of Windows 2003 server.  The ad server is very good, it is used for many other things.

  I've implemented ACS as defined nit it installation guide, including all the steps in the "Member Server" section of the installation guide
  When you use AD as an external database (e.g. setting up services to run with a domain administrator account, set up a machine called "CISCO"
  on the field, etc.).

  I've set the unknown user policy to use the database of Windows, if the internal database does not contain the details of the user.

  If I add a user to the internal database, authentication goes through fine, with an entry in the journal "Authentication," spent

  02-24-2010, 05:07:03, authentic failed, eXXXX, Network Administrators (NDG), X.X.X.X, (default), internal error, (get the internal error error message)

  I scoured google etc and just cannot come up with any reason why this should be the case.
  I followed all of the installation to the letter guides.  I need to get this up and running as soon as possible,
  so am eager to know if someone can help me with this one!

  Thanks and greetings

  Sharan

  George,

  Internal error is fairly generic, but a common situation, we see this error is when ACS is installed on a

  64-bit computer.  ACS would not work with the active Manager when it is installed on the 64-bit before machines

  ACS 4.2.1.

• Cisco ISE machine has no machine authentication

  Hey, since we migrated to ISE 1.2 patch 7 we have problems with our company SSID.

  We have a rule that essentially says:

  The user is a domain user.

  The machine is in the field.

  But for some reason, some workstations are is denied by this:

  ISE 24423 was not able to confirm the previous machine successfully authentication of user in Active Directory

  I was wondering if I could force a sync?

  Hmm, you when you restart the machine you should see an entry of authentication which starts by "host /" Let's try this:

  1 uncheck the box 'Remove' repeated successful authentications and the "suppress abnormal customers'

  2. wait 10 minutes

  3. restart the computer and try again and let us know what happens

• [ACS 5.4] PEAPv1 authentication with MAC filtering

  Hello

  Our WiFi use the PEAPv1 authentication.

  It works very well with different devices (computer, tablets, smartphones).

  Now, I want to filter the devices of the company. We have all the MAC addresses of these devices.

  Is it possible to activate authentication PEAPv1 combined with MAC filtering in Cisco ACS?

  I don't want to filter addresses MAC on WLC...

• 5.2 ACS with different RADIUS authentication servers

  Hello

  I want to migrate from ACS ACS 5.2 4.1. I have already configured authentication GANYMEDE +, but now I've stuck to the RADIUS authentication for remote access WebVPN configuration. Please see the following diagram:

  

  I want to configure ACS to use Server Token WBS first. If authentication fails or the user is not found, ACS must use IAS in Windows Server. If this server fails also ACS must use internal DB. Additional attributes as belonging to a group or ACL downloadable should be taken from internal ACS DB.

  Is it possible to configure ACS like that? ACS 4.1 it is very easy to configure by selecting the per user authentication method.

  Thanks for your help!

  There is an option in the Advanced tab of definition 'RADIUS Identity server' th:

  This storage of identity differentiates between 'authentication failed' and 'user not found' when an authentication attempt is rejected. Among the options below, select how a rejection of authentication of the identity store must be interpreted by FAC for the politics of identity of treatment and reports.
  Releases to treat as 'authentication failed' treat dismisses them as "user not found".

  In order to continue in the sequence, I think you have to select the option "user not found".

• Cisco ACS. Two-factor authentication.

  Hello.

  We intend to use the connection diagram: cisco asa + cisco acs 5.4 + rsa securid.
  We use two groups on Cisco ACS. Group "A" must use two-factor authentication, and the 'B' group don't.
  How to create this rule?

  Perform the rule base identity selection with dap-tunnel-group-name as a selector.

  ASA will send auth request name of the tunnel group.

• Cisco ACS taccas + problem with authentication

  I'm having a problem authenticating to a switch using taccas + my ACS 5.2 server. I can actually do a 'test of aaa group taccas + username password inheritance' and returns a successful user authentication. When I try to use this same account to authenticate the switch, it is unsuccessful, and I'm not even that attempt to hit GBA.

  Most likely, is a configuration of Miss of the AAA command on the switch.

  Hello

  Can you please access the ACS CLI through SSH or Console and run "display the acs application state? Are all ACS services running or some hang on the State "Initializing" or "not tested"?

  If so, you might want to try a restart of services ACS with 'stop acs', then 'start acs '.

  If the reports are not displayed on the follow-up and reports it is generally considered a problem with ACS View services.

  I hope this helps.

• ACS 4.2 RSA Authentication and LDAP group mapping

  Hello

  I have a firewall, PaloAlto, with overall protection enabled (SSL - VPN) feature

  I use Cisco Secure ACS as a proxy for the RSA SecurID authentication.

  After authentication is try to map ad through LDAP query groups.

  The question I've found, is that the user I get with user authentication has no field:

  Show user ip-user-mapping all | mbm60380 game

  10.240.1.24 vsys1 UIA 2388 2388 domain\mbm60380

  10.240.1.1 vsys1 UIA 2101 2101 domain\mbm60380

  10.240.250.1 mbm60380 2590859 2590859 vsys2 GP

  But the list of users that I receive from the LDAP query includes the domain prefix:

  See the user group name domain\group1 property

  short name: domain\group1

  [1] domain\aag60368

  [2] domain\ced61081

  [3] domain\jas61669

  [4] domain\mbm60380

  [5] domain\pmc61693

  [6] domain\vcm60984

  I would like to create the user with the area of GBA but it must delete the domain before querying the RSA server, as it does not support field stripping.

  I tried to fix this on the Palo Alto firewall without success.

  I'm trying to run Cisco Secure ACS 4.2 changing, but it did not work either:

  RSA servers are configured as an external database.  They are not defined in the groups of network devices.

  Can I set up domain stripping for queries servers RSA?

  Thank you

  Hello

  I think it should work, but it is a bit awkward:

  Create an entry in the Distribution of Proxy in the Network Configuration.

  DOMAIN\\USER *.

  Prefix

  Before returning to the AAA server, from there to authenticate to the server RSA without the domain prefix.

  Make sense?

  Thank you
