Cisco ISE NDES EAP and HTTP certificates from different CA
Hi guys, hope this is something you can help with…
2 x ISE 1.2 (patch 5) 3415 appliances with hostnames webproxy1.customerdomain.com and webproxy2.customerdomain.com
AD integration with customerdomain.local
Guest authentication (CWA) using a separate interface on the ISE appliance (Gigabit 1) routing into its own VRF for isolation
Corporate authentication is using EAP-TLS which is working fine
BYOD using NSP with SCEP for iPads only at this stage using NDES on <customerdomain.local>
I have installed a signed GlobalSign server certificate for HTTPS for guests (with SAN fields webproxy1.customerdomain.com and webproxy2.customerdomain.com)
I have also installed a signed server certificate from the customer's CA for EAP (with CN of psn.customerdomain.local and SAN fields psn.customerdomain.local , webproxy1.customerdomain.com and webproxy2.customerdomain.com)
The issue I have is if the two certificates are assigned for EAP and HTTP respectively the NSP process fails to generate a certificate though SCEP to the NDES server.
As soon as I use the same internally signed certificate for HTTP and EAP it works, this then causes a problem with the HTTPS certificate being trusted by guests.
This does not work with the GlobalSign certificate being used for both HTTPS and EAP, only the internal one works.
Can you confirm if it is a valid design to have the ISE use one certificate for HTTPS and another for EAP signed by different CAs, it appears it has to be the internal CA used in the SCEP process to work.
Thanks
Andy
I have now tested this with a test HTTP cert signed by a public CA and an EAP cert signed by my internal and SCEP works fine. I am wondering if this is a certificate tier length issue. My working example has a RootCA->IssuingCA->Cert. It fails with a cert with a 3-tier heirarchy RootCA->IntermediateCA->IssuingCA->Cert.
Can anyone confirm this works on other deployments with a 3-tier certificate chain with SCEP?
Thanks

I want to integrate SMS gateway to Cisco ISE 1.2 and my question is
SMS notifications are supported for Guest self−registration Services ? or it should be done by SponsorI'm not sure I understand the question. Do you want to log in to the Sponsor Portal using AD credentials?
Create an Identity Source Sequence using AD as an Authentication Source. Go to Administration > Identity Management > Identity Source Sequences. Either Edit or +Add a Sequence and choose from the Authentication Sources shown.
Then choose that Identity Source Sequence by going to Administration > Web Portal Management > Settings. Double-click Sponsor from the Left Menu and click Authentication Source. Choose the Identity Source Sequence. Click Save.
I hope this helps.

Cisco ISE with EAP-FAST and PAC provisioning
Hi,
I have search with no result on this topic. So, Does anyone have implemented Cisco ISE authentication with EAP-FAST and PAC provisioning ?
Since I have an issue with internal proxy, user required to authenticate with an internal proxy before granting access to the internet.
If you have any documents, it would be appreciated for me.
Thanks,
PongsatornFrom what I understand a Internet proxy PAC and a eap-fast PAC are two different purposes.
Is that what you are trying to get clarification on.
Basically eap fast PAC provisioning is a PAC that s provisioned when a client authenticates successfully. The client provides this PAC for network authentication and not proxy authentication.

Cisco ISE 1.2 and AD Group
Hello,
I have Cisco ISE installed on my EXSi server for my test pilot. I have added several AD groups to ISE as well.
I have created an Authorization policy condition, which is WIRELESS_DOT1X_USERS (see screenshot)
Basically, I just duplicated the default Wireless_802.1X and added Network Access:EapAuthentication, Equals, EAP-TLS.
My problem is, I was unable to join the wireless network if I added my AD group to the Authorization policy (see screenshot). The user that I have is a member of WLAN-USERS. If I removed the AD group from the Authorization policy, the use is able to join the wireless network.
I attached the ISE logs screenshot as well. I checked the ISE, AD/NPS, WLC, laptop time and date, and they are all in synched.
I also have the WLC added as NPS client on my network.
I checked the AD log and what I found was the WLCs local management user trying to authenticate. It is supposed to be my wireless user credential not the WLC.
This is the log that I got from the AD/NPS
Network Policy Server denied access to a user.
Contact the Network Policy Server administrator for more information.

I got my AD group working. What I did, I checked the user's certificate that is installed on the laptop then modified the ISE certificate authentication profile to "Subject Alternative Name". I had the ISE set to common name when I was having an issue.
I forgot to mentioned that I have to servers in my ISE test pilot. I have AD with NPS, and CA. These servers are Windows 2008 R2.
I am a little confuse about the attribute in certificate template you have mentioned. Is that located at Certificate Authority/server-name/Certificate Templates/Users? I am not sure where to look for that attribute on the CA server. -
ISE 1.2 and iPEP Certificate Requirements
Hi,
For 1.1.x version of ISE, there are some constraints regarding the certificates used for iPEP and Admin:
Both EKU attributes should be disabled, if both EKU attributes are disabled in the Inline Posture certificate, or both EKU attributes should be enabled, if the server attribute is enabled in the Inline Postur certificate.
[http://www.cisco.com/en/US/products/ps11640/products_configuration_example09186a0080bea904.shtml]
Does the same thing applies for iPEP in ISE 1.2? The User Guide for ISE 1.2 and Hardware Installation Guide doesn't mention anything about EKU and specific certificate attributes..
Any thoughts?
Thank you,
OctavianThe EKU validation has been removed in version 1.2
"If you configure ISE for services such as Inline Policy Enforcement Point (iPEP), the template used in order to generate the ISE server identity certificate should contain both client and server authentication attributes if you use ISE Version 1.1.x or earlier. This allows the admin and inline nodes to mutually authenticate each other. The EKU validation for iPEP was removed in ISE Version 1.2, which makes this requirement less relevant."

ISE 1.2 and multiple certificates
Hello,
Hopefully someone can answer this question. We have ISE 1.2 setup and running, 802.1x and user and computer certificates. All is working fine except some users have two user certificates, one from our server the other from our parent company. When these users log in they get a bubble message saying "additional information is required to connect to the network", they click on this and they are asked to pick a certificate. If they pick the one from us all works.
Question, is there a way either in Windows or ISE to use our certificate by default? The PCs in question all have the cisco NAC agent, 4.9.43, and are either XP, Windows 7 or 8.
ThanksThanks for the response but it's wrong. Cisco supports stacked ports in 1.2 for wired users. They carried over 1.1documentation to 1.2 and never updated it. We have it in writing from Cisco tac.

Web Redirection Problem on Cisco ISE 1.2 and WLC 7.5
Hello,
We are at initial phase of deploying ISE 1.2 in our environment for Wireless Guest Users.
I have configured ISE and WLC to talk to each other which is working fine. An SSID with MAC-Filtering is also configured on WLC and ACL only allowing ISE and DNS traffice.
I have configured proper authentication and authorization policies on ISE. Now, when I try to connect my device (laptop and android mobile), I see my device gets associated with the SSID (Demo) and gets the right IP Address from DHCP and right VLAN from WLC. The log process on ISE is as follows.

I also see a redirect url in the detailed authentication logs. But the problem is that when I open my browser on my device, it doesn't get redirected to the guest portal url. Now since I can't get there, I can't continue with the rest of the process of authentication, COA and final ACL for internet access.
Can some one please either guide me the correct steps that I need to follow, if I have mis configured something or advise if this is a bug.
Thanks in advance.
JayThe ACL is definitely used to define what traffic is re-directed to ISE and what traffic is not redirected. Having the permit-all statement at the end will break redirection. If you are using flex-connect then you will need to use flex-connect ACLs and apply those to the flex-connect APs. The links below should give you an idea of what needs to be done:

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 with TACACS+ and RADIUS both?
Hello,
I am initiating wired authentication on an existing network using Cisco ISE. I have been studying the requirements for this. I know I have to turn on RADIUS on the Cisco switches on the network. The switches on the network are already programmed for TACACS+. Does anybody know if they can both operate on the same network at the same time?
BobHello Robert,
I believe NO, they both won't work together as both TACACS and Radius are different technologies.
It's just because that TACACS encrypts the whole message and Radius just the password, so I believe it won't work.
For your reference, I am sharing the link for the difference between TACACS and Radius.
http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a0080094e99.shtml
Moreover, Please review the information as well.
Compare TACACS+ and RADIUS
These sections compare several features of TACACS+ and RADIUS.
UDP and TCP
RADIUS uses UDP while TACACS+ uses TCP. TCP offers several advantages over UDP. TCP offers a connection-oriented transport, while UDP offers best-effort delivery. RADIUS requires additional programmable variables such as re-transmit attempts and time-outs to compensate for best-effort transport, but it lacks the level of built-in support that a
TCP transport offers:
TCP usage provides a separate acknowledgment that a request has been received, within (approximately) a network round-trip time (RTT), regardless of how loaded and slow the backend authentication mechanism (a TCP acknowledgment) might be.
TCP provides immediate indication of a crashed, or not running, server by a reset (RST). You can determine when a server crashes and returns to service if you use long-lived TCP connections. UDP cannot tell the difference between a server that is down, a slow server, and a non-existent server.
Using TCP keepalives, server crashes can be detected out-of-band with actual requests. Connections to multiple servers can be maintained simultaneously, and you only need to send messages to the ones that are known to be up and running.
TCP is more scalable and adapts to growing, as well as congested, networks.
Packet Encryption
RADIUS encrypts only the password in the access-request packet, from the client to the server. The remainder of the packet is unencrypted. Other information, such as username, authorized services, and accounting, can be captured by a third party.
TACACS+ encrypts the entire body of the packet but leaves a standard TACACS+ header. Within the header is a field that indicates whether the body is encrypted or not. For debugging purposes, it is useful to have the body of the packets unencrypted. However, during normal operation, the body of the packet is fully encrypted for more secure communications.
Authentication and Authorization
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates on a Kerberos server, it requests authorization information from a TACACS+ server without having to re-authenticate. The NAS informs the TACACS+ server that it has successfully authenticated on a Kerberos server, and the server then provides authorization information.
During a session, if additional authorization checking is needed, the access server checks with a TACACS+ server to determine if the user is granted permission to use a particular command. This provides greater control over the commands that can be executed on the access server while decoupling from the authentication mechanism.
Multiprotocol Support
RADIUS does not support these protocols:
AppleTalk Remote Access (ARA) protocol
NetBIOS Frame Protocol Control protocol
Novell Asynchronous Services Interface (NASI)
X.25 PAD connection
TACACS+ offers multiprotocol support.
Router Management
RADIUS does not allow users to control which commands can be executed on a router and which cannot. Therefore, RADIUS is not as useful for router management or as flexible for terminal services.
TACACS+ provides two methods to control the authorization of router commands on a per-user or per-group basis. The first method is to assign privilege levels to commands and have the router verify with the TACACS+ server whether or not the user is authorized at the specified privilege level. The second method is to explicitly specify in the TACACS+ server, on a per-user or per-group basis, the commands that are allowed.
Interoperability
Due to various interpretations of the RADIUS Request for Comments (RFCs), compliance with the RADIUS RFCs does not guarantee interoperability. Even though several vendors implement RADIUS clients, this does not mean they are interoperable. Cisco implements most RADIUS attributes and consistently adds more. If customers use only the standard RADIUS attributes in their servers, they can interoperate between several vendors as long as these vendors implement the same attributes. However, many vendors implement extensions that are proprietary attributes. If a customer uses one of these vendor-specific extended attributes, interoperability is not possible.
Traffic
Due to the previously cited differences between TACACS+ and RADIUS, the amount of traffic generated between the client and server differs. These examples illustrate the traffic between the client and server for TACACS+ and RADIUS when used for router management with authentication, exec authorization, command authorization (which RADIUS cannot do), exec accounting, and command accounting (which RADIUS cannot do). -
SA540 and SSL certificate from DigiCert
Has anyone succeeded in installing a SSL certificate from DigiCert on a SA540 router?
The SSL certifcate is a wildcard variant (*.example.com).Hello Mr. ivar,
In order to get a new SSL certificate please follow the next instructions:
STEP 1 : Click Administration > Authentication.
The Authentication (Certificates) window opens.
STEP 2 For each type of certificate, perform the following actions, as needed:
• To add a certificate, click Upload. You can upload the certificate from the PC or the USB device. Click Browse, find and select the certificate, and then
click Upload.
• To delete a certificate, check the box to select the certificate, and then click
Delete.
• To download the router’s certificate (.pem file), click the Download button under the Download Settings area.
STEP 3 To request a certificate from the CA, click Generate CSR.
The Generate Certification Signing Request window opens.
a. Enter the distinguished name information in the Generate Self Certificate
Request fields.
• Name: Unique name used to identify a certificate.
• Subject: Name of the certificate holder (owner). The subject field populates the CN (Common Name) entry of the generated certificate and can contain these fields:
- CN=Common Name
- O=Organization
- OU=Organizational unit
- L= Locality
- ST= State
- C=Country
For example: CN=router1, OU=my_dept, O=my_company, L=SFO, C=US
Whatever name you choose will appear in the subject line of the generated CSR. To include more than one subject field, enter each subject separated by a comma. For example: CN=hostname.domain.com, ST=CA, C=USA
• Hash Algorithm: Algorithm used by the certificate. Choose between MD5 and SHA-1
•Signature Algorithm: Algorithm (RSA) used to sign the certificate.
• Signature Key Length: Length of the signature, either 512 or 1024.
• (Optional) IP Address, Domain Name, and Email Address
b. Click Generate.
A new certificate request is created and added to the Certification Signing Request (CSR) table. To view the request, click the View button next to the certificate you just created.

Cisco ISE: Dot1x failing and MAB succeeded (Intermittent) /or Posture Delay
Hi,
We are running the cisco ise 1.1.3 and configured for the Dot1x and MAB authentications. PC's are getting access through MAB while Dot1x failing again and again. But, sometime, same PC is getting authenticating via Dot1x. Connectivity is intermittent. Also, sometimes, stucks longer in Posture
We have three different switches at the moment with the latest IOS version.
1) WS-C4507R-E = 15.1(2)SG,
2) WS-C3560-48PS = 12.2(55)SE7
3) WS-C3750X-24P = 15.0(2)SE1
Could you anyone pitch the idea? or advise about the latest IOS for the switches.
Let me know, if you need more information.
Thanks,
Regards,
MubahserIt seems your PCs are failing dot1x and also failing MAB authentication, the switch by default will start the process again and will again fail dot1x and MAB authentication, and so on.
It will be helpful to see the logs from both the switch and the radius servers (i take it is ACS or ISE). Also the configuration of the radius server. -
Always Access Denied when choosing Automatically Enrol and Retrieve Certificates from MMC
I am using 2008 R2 Certificate Services to issue certs across multiple forests (although don't let that muddy the waters).
I have a need to issue certificates for use with s/ldap, so I have duplicated the Kerberos cert and removed all Intended Purposes other than Server Authentication and configured appropriate security to allow Domain Controllers/Domain Admins to enrol.
The certificate also requires CA Manager Approval.
Everything looks good - I am able to enrol for the cert via the MMC, the request goes into pending, and I am then able to issue the cert. However, when I go back into the MMC on the Server that requested the cert and choose All Tasks | Automatically
Enrol and Retrieve Certificates, I choose the pending cert and then get Access Denied.
On the issuing Server, I get an Event 21 in the App Log:
Active Directory Certificate Services could not process request 8466 due to an error: Access is denied. 0x80070005 (WIN32: 5). The request was for CN=server.domain.com.
On the Server that requested the cert, I get an Event 9:
Certificate enrollment for Local system was denied by servername\Issuing CA when retrieving the pending request for a SecureLDAPCertificate certificate with request ID 8466.
The strange thing is, if I follow this procedure but using the certsrv website, it works fine and I can install the certificate.
What am I missing? Or is this one of those random quirks of AD CS?
Any help is appreciated.Hi,
Thanks for posting in Microsoft TechNet forums.
According to the error messages you provided, this can be a permission issue.
The method of Autoenrollment for a certificate depends on an Active Directory. Considering using Certsrv website was successful, the problem can be that the requester does not have enough permission to access the certificate template in Active Directory
To autoenroll a certificate template, a user or computer must belong to a security group that is assigned the read,enroll,and autoenroll permissions.
Only groups that are assigned these permissions are enabled for autoenrollment.
Could you please answer the following questions for us so that we can troubleshoot the issue more effectively?
Are the issuing CA server and the requesting CA in the same forest/domain?
regards
Ted
