ISE subordinate CA

Guys,
Having a lot of bother with getting ISE to work with a subordindate CA. We are implementing a wireless Proof of concept for our customer useing ISE as the security element.
The customer would rather not change any settings on the root CA and would like to use a sub CA for scep. Im not sure what the setup should look like with the Root and Sub ca.
Should ise be signed by the sub CA if we are using the sub for scep? Or can we point the scep server to the Root when setting up the NDES service on the scep server?
At the minute the ISE node is signed by the root CA. When i add the sub as  the scep server it submits successfully but recevie NDES errors and prompts from apple devices saying the response from the scep server is incorrect. I can post any errors if that helps. Just looking guidance as I have no real experience with certs at all. Thanks
Update: Error on the scep server is:
The Network Device Enrollment Service cannot decrypt the client's PKCS7 message (0x80090005). Bad Data.

Cisco  ISE relies on public key infrastructure (PKI) to provide secure  communication for the following:
•Client and server authentication  for Transport Layer Security (TLS)-related Extensible Authentication  Protocol (EAP) protocols
•HTTPS communication between your  client browser and the management server
Cisco  ISE provides a web interface for managing PKI credentials. There are  two types of credentials:
•Local certificates—Used to identify  the Cisco ISE server to other entities such as EAP supplicants,  external policy servers, or management clients. Local certificates are  also known as identity certificates. Along with the local certificate, a  private key is stored in Cisco ISE to prove its authenticity.
Cisco ISE identifies when a local certificate is about  to expire and logs a warning in the audit logs. The expiration date  also appears in the local certificate list page (Administration >  System > Certificates > Local Certificates). The audit log message  is logged in the catalina.out file. You can download this file  as part of the support bundle (Operations > Troubleshoot >  Download Logs). The catalina.out file will be available in this  directory: support\apache_logs. There are two types of audit log  messages that provide information on local certificate expiration  warnings:
–Certificate expiring in < 90  days—AuditMessage: 34100: Certificate.ExpirationInDays,  Certificate.IssuedBy, Certificate.CertificateName, Certificate.IssuedTo
–Certificate has  expired—AuditMessage: 34101: Certificate.ExpirationDate,  Certificate.IssuedBy, Certificate.CertificateName, Certificate.IssuedTo
•Certificate authority  certificates—Used to verify remote certificates that are presented to  Cisco ISE. Certificate authority certificates have a dependency relation  that forms a Certificate Trust List (CTL) hierarchy. This hierarchy  connects a certificate with its ultimate root certificate authority (CA)  and verifies the authenticity of the certificate.
Please Check  the below link for managing the Certificates in ISE.

  • ISE - Multiple Issuing Subordinate CAs for EAP Auth?

    Is it possible to utilise multiple issuing subordinate CAs with an ISE implementation? In short I have a situation where the client is wanting to issue certificates for one group of users from CA1 and issue certificates for another group of users from CA2.
    As far as I can see it is not possible to have two different server certificates installed on a policy node for the purposes of EAP authentication. Is the only way around this to install a policy node per issuing certifcate server?

    Ok to add to this I would really like some clarification on certificate installation for the purposes of EAP-TLS. The Cisco doco is at best vague on this topic. I have a distributed deployment with 2 x Admin, 1 x monitoring and 2 x PSN. I have installed a Public HTTPS server auth cert on each device and all nodes are joined. I would now like to utilise MS CA cert infrastructure to authenticate EAP-TLS.
    My understanding is that I need the MS CA Root Cert and Subordinate Cert on the Admin node with the subordinate cert ticked for trust for EAP Auth. Is there a requirement for a Server Authentication certificate on the Admin Node? Going forward with that Is there a requirement to add a server authentication certificate to the PSN Nodes?
    In addition back to my first question is it possible to utilise multiple subordinate CAs for client authentication if so how as I cannot seem to click trust for EAP on multiple certs

  • ISE 1.3 - internal CA for EAP client

    Hi Experts,
    Could you please give me the right way and step to configure ISE 1.3 built in CA for EAP client auth. I'm trying to complete my dual SSIDs procedure. My configure may has some missing config on Certificate section. That make client can not get through device enrollment & provisioning but auth, authorise are fine.
    It s hard to config 100% correctly with out detailed guide. I know by fundamental setup the config must comprise of subordinate CA, OCSP, endpoint RA which I can not figure out those steps myself.
    The steps or complete document are welcome. Official document does not help me get through. 
    Thank you in advance,
    Nipat CCIE#29422

    I would like to see something similar if anyone has anything with a little more detail then what the Admin Guide has.

  • ISE's Internal Root CA. How to generate new one in distributed deployment?

    Hello,
    I have two ISE nodes in distributed deployment. I would like to generate new Internal Root CA certificate. I was able to do that from primary node, but only FOR primary node. How can I achieve this for the other node?
    Best Regards,
    Marek

    Hi Marek-
    All of the certificate management is performed from the Admin Node which becomes the Root CA for the ISE PKI. You generate Subordinate CA certificates to your Policy Nodes from the Primary Admin node. Check this link for more info:
    http://www.cisco.com/c/en/us/td/docs/security/ise/1-3/admin_guide/b_ise_admin_guide_13/b_ise_admin_guide_sample_chapter_01000.html#task_FF93B4C51BAC4CA196A48B607DAA595D
    Also, since the primary node is the Root CA, you should export the certificate and the private key and import it to your secondary Admin node. This will enable the secondary node to be promoted to a Root CA in case of a failure of the primary admin node:
    http://www.cisco.com/c/en/us/td/docs/security/ise/1-3/admin_guide/b_ise_admin_guide_13/b_ise_admin_guide_sample_chapter_01000.html#concept_435C4E3FF56949B1B4D5A0C73671AB22

  • Logical Profiles in ISE 1.2.1

    I´m having trouble understanding the Logical Profiles. 
    What I understand from the user guide: http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/user_guide/ise_user_guide/ise_prof_pol.html#58510
    for those to lazy to read: 
    You can use the logical profile in an authorization policy condition to help create an overall network access policy for a category of profiles. You can create a simple condition for authorization, which can be included in the authorization rule. The attribute-value pair that you can use in the authorization condition is the logical profile (attribute) and the name of the logical profile (value), which can be found in the EndPoints systems dictionary.
    so I thought that meant that I can group Different Profiles (Apple Iphone, Ipad, Ipod) together into a logical group e.g. "BYOD_Idevice" and use this logical profile in the Authorization. 
    But I can´t choose this freshly created Logical Group in the Authorization Condition. As for the fact, I can´t choose this logical group ANYWHERE. 
    Leaning back and thinking about it - it somehow makes sense. In the Authorization, you don´t pick Profiles, you choose Identity endpoints. So whats the point about the logical profiles? I was hoping to clean/lean up my authorization rules with them. But for what would I use them else? 
    Or is this a bug in ise 1.2.1? Not sure if I should call tac about this, or if I´m just not getting it :D
    Thanks alot for your help!  

    Nice username! :)
    So yes, you are correct, the logical profiles would allow you to group different type of dynamically profiled devices and then reference that profile in your authorization rules. However, you won't see those logical profiles under the "Identity Group Details" section. You will need to leave that field blank. Instead, you need to look in the "second" condition box: expression > Endpoint > LogicalProfile
    Hope this helps!

  • Caching credentials for webauth in ISE 1.2?

    We are providing internet access through a Guest portal. The portal is provided by the ISE through webauth and the user is created through the ISE Sponsor Portal.
    When an account is created and the enduser logs in to it, I would like for the ISE to cache the credentials for that user for a period of time; at least 1 or more days before it prompts them to log back in again. Right now, if a user disconnects for a short period and then goes to reconnet, it prompts for the username/password again.
    Where (and how) in the ISE do you configure that?
    Thank you.                  

    Thanks for the quick reply Charles. I am reading through the details of it now.
    It looks like DRW basically registers the MAC of a connecting device in an identity store and then allows that device to connect. Does it still match the MAC to a guest user so that we can set time profiles against it and does it expire like the guest accounts do?
    Any ETA on the release of ISE 1.3?

  • Intermittent AD Authentication failures in ISE 1.2

              Starting today I was getting intermittent authentication failures in ISE. It would say that the user was not found in the selected identity store. The account is there though. At one point I ran a authetication test from the external identity source menu and I got a failure and then the next time a pass. I have no idea why this is happening. I just updated to ISE 1.2 the other day. I'm also seeing what looks like a high level of latency on both of my PSN's. Is this normal?  Any ideas?
    Thanks
    Jef

    Interesting. I have one location that is not having this problem at all. The other is having it somewhat frequently. The PSN's for each location are tied to the local AD servers. I have not had this until we started getting 300-380 PC's connecting. We are a school so we are slowly getting started. It's real random. One user will work then another time they won't. Happens with admin and user. I have notices that with this new version of ISE it is complaining that it is getting accounting updates from the NAS too often, but I have not looked into this because I just installed 1.2 about 3-4 days ago and haven't had time to look into it.
    When you say Multicast to you AD...how did you check that? We do use multicast.

  • Double lookup possible in ISE 1.2 ?

    I want to do MAB on a certain SSID and authenticate and register devices used in the SSID.
    I managed to do that. If not "RegisteredDevice" then redirect to a portal where users can login with AD account and register there devices.
    After registration, the device MAC is added to "RegisteredDevices" and the endpoint is profiled.
    The ISE database contains an endpoint profile and this profile contains the propertie "BYODRegistration" = yes and "PortalUser" = the AD account xxx@ADdomain.
    Now i want to link the state of the AD account to the database. When the user account is locked/expired/disabled, the device should be refused.
    I wonder if it is possible to do the following:
    MAB authentication occurs -> lookup MAC address in Registered Devices (=OK), lookup "Portal User" of device -> Query AD for this user, get property "UserAccountControl". Based on this property, i can determine if account is still active. If yes -> allow access. If not -> refuse access, even if device is in "RegisteredDevices".
    When i troubleshoot however, i notice that -when using MAB- ISE is trying the MAC address as username against AD and gets returned: "Unknown User", of course. Is there a way to use the linked "PortalUser" as username against AD instead of MAC address ?
    [NOTE: i am fully aware that the proper way of doing this is through Client Provisioning and Certificates with a second SSID using 802.1x to authenticate certificates, but for now, i want to prevent pushing anything to the clients.......]

    Too bad.
    I wish Cisco had implemented a property like this: RegisteredDevices:PortalUser:IdentityAccessRestricted
    (i am assuming PortalUser is an AD account here). Maybe a PER can help.....

  • Bug CSCup27305 in ISE 1.2.1.198 patch3

    Hi guys,
    I´m hitting bug CSCup27305 in version ISE 1.2.1.198 patch3 but cant find a fix version.
    Do you know what version can be applied, so DACL can start with permit IP Host 2.2.2.2 Host 1.1.1.1 = is NOT ok!
    Thanks a lot for your help.
    Erick Flamenco

    It is not resolved in any shipping version and will currently be in first release that ships post 1.3
    Note that this issue impacts DACL validator functionality in that does not detect the invalid DACL as it should but does not impact any end to end functionality and so may not get priortized for any earlier patch

  • Authentication Combination in ISE 1.2

    Is it possible to have dual authentication using workstations auth certs and Windows domain credentials for authentication in ISE 1.2?

    This would be a client side configuration.
    What type of authentication is this?
    VPN? wired or wireless dot1x?

  • Logical Profiles in ISE 1.2

    I created a logical profiles group that is assigned with the Apple-ipad, Apple-iPhone and Apple-iDevice policies. Now ISE will not update the feed policies for the three devices. This is the message that I recieved from ISE when it does it Feed Polices update, I use the logical profiles group matching for authentication and authorization. Is there any way for me to update these feed polices? Thanks for the help!!

    Hello Toua,
    Please Verify switch configuration for those network segments where endpoints are not being appropriately profiled to ensure that:
    •The required information to profile the endpoint is being sent to Cisco ISE for it to profile.
    •Probes are configured on the network Policy Service node entities.
    •Verify that packets are received at the Cisco ISE profiler module by running the tcpdump function at Operations > Troubleshoot > Diagnostic Tools > General Tools > Tcpdump.
    Note If you are observing this issue with endpoints on a WAN collected by HTTP, Netflow, and NMAP, ensure that the endpoint IP address has been updated with a RADIUS/DHCP Probe before other attributes are updated using the above probes

  • ISE 1.2 patch 4 not retrieving groups

    Since the update to ISE 1.2 patch 4 it isn't possible anymore to retrieve groups or attributes from the active directory. It keeps loading.
    Anyone else experiencing this issue?           
    Regards,
    Mathieu

    The issue you are referring to is documented in the following CDETS:
    CSCul84544: Retrieval of AD groups or attributes is failing
    This is not yet resolved. May be resolved in a future patch
    The workaround given in the CDETS is
    Fix the DNS server so that the reverse DNS lookup matches
    I believe there are other steps that can be taken to mitigate this but would need intervention from TAC

  • ISE 1.2 Authentication fails for 2nd AD domain with the forest trust relation

    We are running cisco ISE 1.2, we have new AD domain with forest trust relation between both the new and the old. authentication to with the new domain fails.
    Is there any requirements or configurations change needs to be done to make it success?

    Use the license that is currently on your ISE.  If your account has access to download the software, then you are good.  The license will not change during the upgrade.  If you are using ISE 1.2 Patch 8 or above, then you are using the same Base/Plus?Apex Licensing model. 
    If you are not yet on Patch 8, the you are using Base/Advanced and these will be converted during the upgrade.
