Cisco AAA/Identity/Nac :: Install Certificates On ACS 5.2
Jan 31, 2012
I have generated request and our CA server gave us two files, one is certificate from CA itself, one is the certificate CA created for the ACS. I used the "Bind CA Signed Cerficate" under "local certificated"Option to bind the latter. it shows successful.and a web access from any pc will give you error info, "that the security certificate presented by this website was issued for a different website's address." And all the while I dont know how to deal with the other file, which is "Internal CA certificates" I was try to use the first option import server option, but it seems not right,

is there a easy to install SSL certificate on ASA, rather than enroll with a public CA? ASDM has a place to import certificates. Can I just upload a SSL certificate I got from my CA to ASA, withou setup CA enrollment? And if yes, how can I generate a SSL certificate request from my ASA 8.2?

I want to use multiple cert (enterprise certs and verisign cert) for authentication in wireless.Users that have their computer in the domain should use EAP-TLS and PEAP (verisign) are for users in the domain but on non-domain computers.I can only enable one certificate in system adminstration->local server certificates-> local certificates to use EAP.I have installed both enterprise and verisign cert in the CA store in User and Identy store and enbled the enterprise cert for EAP-TLS.The EAP-TLS connection works fine when the enterprise cert is enabled for EAP (in local certificates) but PEAP does not. If I enable EAP on the verisign cert in local certificates the enterprise cert get EAP disabled and that authentication stops working av PEAP starts working.
Is the ACS5.2 only able to have one certificate enabled at the time for EAP?

how the certificates work when using PEAP on ACS 5.2.Currently we have clients which are Cisco wireless IP phones that are using the ACS server(s) for authentication to the wireless network. The phones are configured to use PEAP with server validation enabled. The phones have a Godaddy root certificate, and Godaddy intermediate certificates installed on them, (in addition they have all the certs that are on the phone by default). On the ACS server there is a certificate that is signed by Godaddy. This was creating doing the CSR process etc...
So from what I understand, because all the phones are set up to validate the server certificate, they require the public root certs and the intermediate certs that are installed on them, in order to validate the private cert that is on the ACS server. The private certificate (the one signed and issued by Godaddy), expires the middle of next year (2014) (a little ways off I know, but it is never too early be concerned about stuff). When we go to get a new private certificate for the ACS servers (or get a renewal) and when we install this new signed certificate onto the ACS servers…will all the clients still trust this new certificate, and everything will continue to work smoothly? Or will the clients all need to have new root certs installed, and new intermediate certificates installed? From what I can gather I think the first scenario should be the case, because the root certs and intermediate certs are there to trust certs that are signed by Godaddy, so as long as the new private certificate is signed by Godaddy everything should be okay.

I have a Cisco 4506 With IOS 12.2 54SG1
Iam new on Acs 4.2 and i want to use Certificates to authenticate my windows XP Client and Igels.
On Windows Xp i selected : IEEE 802.1X Authentication enable EAP (Peap)
But i dont understand the Certification of ACS 4.2.
I generated a Self-Signed Certificate. Is this right ? and under installed Certificates the Certificate Status is okay.
Do i have to create for each windows Machine one user Account under user-Setup to authenticate the Machine?
Where do Windows Xp know whitch Certificate he have to take ?
I configures the Switch on Global Configuration like this:
aaa authentication login default group tacacs+ enable
aaa authentication enable default group tacacs+ enable
[Code].....
Iam triying to configure ist szenario till 4 days and it still dont work.. On Windows i Only get the Error" authentication failed" on the Switch the same : dot1x : Authfailed

When I tried to import the file, there are two lines there, One is Certificate file, the other is for "Private Key File".
My question for you is, is this the private key of CA? My understanding has always been that the private key stays in CA only, not going to any other devices.

A PC with a machine cert gets connected to a switch running 802.1x. The switch uses EAP with .1x to query PC, handing this off to ACS, that bit I'm ok with. The ACS needs to query the CA server to authenticate the PC, its this process I'm not sure about.
Reading the documentation I think that I need to configure LDAP between the ACS and the CA, which is running on 64-bit 2008 server. But, ACS SE remote agent is 32 bit only.
Is this correct, if so how do I get ACS SE to communicate with a 64-bit 2008 CA server?

I have been trying to figure out for days now how to get Windows XP/Windows 7 and Apple iPads to connect to a broadcasted SSID and authenticate with PEAP without getting prompted to verify a certificate that exists on ACS.
In Windows 7, I get a window that says the connection attempt could not be completed and get a warning that the certificate could not be validated. If I manually configure a wireless connection and specify PEAP to accept my trusted root certificate authority (in the default list), it doesn't prompt but having users do this is not acceptable and more work than to just verify when prompted. I have no control over the devices connecting so I can't push anything down using GPOs.
For the iPad, I get a similar message that the certificate authority can't be verified and you have to accept.
For the certs, I have tried GoDaddy and Starfield. How to get this working without getting prompted to verify/validate a certificate authority? If so, what cert are you using? I have the intermediate certs installed in ACS and Windows and iPads see them because as soon as I delete, the screen that pops up changes to my actual cert.

I have an ISE 3395 appliance that comes with ISE version 1.1.1.I've decided to upgrade it to version 1.1.2 patch 5 (latest patch version) and played with it for a few days. I set it up as a stand-alone box.
Now, I need to deploy this box as administration and monitoring. So, I put in the command "application reset-factory" to set it back to factory.Does it mean the ISE version of this box will still be at version 1.1.2 patch 5 and I will get a clean box to do whatever I want, similar to Cisco IOS of "write erase" and "reload" to have a clean box?

I'm curently studying for my CCNP Switch certfification, and I'm learning about RADIUS and AAA. I need to practice this topics, but unfortunately I can't find any way to do it. I have cisco ACS 4.2 but I'm unable to install it on my Server 2003 (it says mmc.exe needs to be closed, tried some things but no luck...). I'm unaware of any simulator for RADIUS or anything similar.
how to install ACS 4.2 on Server 2003 (how to solve the error I'm recieving), or point me towards some other product to practise RADIUS and AAA authentication

I have a fresh install of an ACS 5.4 virtual appliance. This ACS instance will only be used for TACACS+ AAA for network device administration. It is up and running on the network. I have time, timezone, NTP and DNS configured. ACS admin accounts and logging are configured. I created an internal user, a network device, a network device group, an internal identity group, a shell profile, and command set. It is joined to the Enterprise Active directory domain, and a couple of AD groups have been selected for use in policies.The default network device is enabled and configured with a TACACS secret. I have a lab router configured and pointed at ACS and I can SSH to it with the ACS internal user.The problem is: I can’t create any rules for any policies. If I try to add a rule (or edit a default rule) to the “Service Selection Rules” or “Default Device Admin” or Identity, group mapping or authorization, all I get is a popup with the message “Resource not found or Internal Server error”. If I click “customize” anywhere I just get empty selection/transfer boxes. If I try to change to a single result policy from compound rules I get a “System failure – your changes were not saved” message. I have installed this twice now with the same results.This is my first experience with ACS. I’ve gotten through most of the configuration guide but I don’t know ACS well enough to know if I’m missing something incredibly obvious, or whether it’s just broken.

I understand that on ACSv5 you can use either "show udi" or "show inventory" to find out the S/N of your ACS appliance....i.e. the S/N that you will use to open a TAC case....however, this particular install is a VM install and when I type either of those commands, under S/N the only thing I see is this: Serial: Cisco-VM-SN.how can I actually locate the S/N of ACS ona VM install to open a case with TAC?

I have access to an ASA running 8.4 and I need to copy the config to another one, to have it has as a spare.All configuration has coppied fine except for this part in the config;
crypto ca trustpoint ASDM_TrustPoint0
enrollment self
subject-name CN=GS2-NT-FIR-01
proxy-ldc-issuer
crl configure
[code]....
So firstly, I assume this certificate is for the SSL vpn that is configured on the ASA? Secondly, this wouldn't copy across (the HEX part). But I believe this ASA is using a self signed cert so instead I probably ned to generate a new one on this spare ASA, so how do I do that?

I am delving into the world of Certificates and the ASA. I am having the HARDEST time grasping this though. I've poured over Cisco whitepapers, been reading through books and things just aren't solidifying in my head. So my question is, how do Certificates for SSL work on the ASA? Where does the data transmit and how does an ASA talk to a CA and User for things?
Lets do this basic topology for the discussion:
End User------SSL VPN---> ASA--->Internal CA
So in theory we are supposed to create a certificate and install it on the ASA and then set the outside interface to trust that cert?
How do identity certs and root certs also work out on the ASA? I have instructions that pretty much say
Create RSA key
Create new trustpoint
cry ca auth newtrustpoint
cry ca enroll newtrustpoint
cry ca import ?
So what are all of these steps specifically doing? Also in ASDM it shows a normal Certificate and an Identity Certificate. I can't really figure out the difference between the two. Does one cert talk to the CA and the other identify the ASA to the CA?

I have an ASA5540 running 8.4(3) which has CA and identity certificates from godaddy.com installed, identifying the ASA to VPN remote users (the are using the anyconnect client.) There is also a separate certificate server located on the inside LAN that is used for internal purposes. All client workstations have identity certs from this internal server.
We would like to be able to continue using the existing godaddy CA/identity certs to identify the ASA to the clients, but we'd like to use the internal CA server to identify the clients when they initiate the AnyConnect session to the ASA.
I have seen other postings that state you cannot have more than one vert on an interface, but this is a little different - only one cert needs to be used to identify the ASA. The other one is only to identify the users. The ASA did allow me to import the internal CA cert.

I've tried to piece this together with SSL Remote Access VPNS, Understanding PKI and the Cisco's ASA 5500 Series Chapter 73 Configuring Digital Certificates. Below is a basic config I use to create the CA and ID certs on ASAs. I use the ASA as the CA server. When I export the SSL trust point it doesn't show chaining from the CA. Since there is no chaining when I load the CA certificate in the Root Store I still an SSL Certificate error. Instead I have to load the SSL Trustpoint Certificate.
CREATE CA
crypto ca server
smtp from-address admin@Cisco.local
lifetime ca 3650
lifetime certificate 3650
lifetime crl 24
[code]....
I originally thought it was a problem with enrollment self in the trustpoint, but I cannot figure out the steps to complete enrollment terminal. I got to the steps of crypto ca enroll Identity_Certificate and displayed the certificate request. At that point the sh crypto ca trustpoint Identity_Certificate is pending enrollment. I can not find the command for the CA that allows trustpoint enrollment. If I try to crypto ca export Identity_Cetificate identity-certificateit says trustpoint not enrolled. Of course if I take the enrollment request and attempt to crypto ca import Identity_Certificate certificate it fails because it's not the cert.

We're looking to deploy a certificate-based VPN solution for users with mobile devices (iPhone, iPad, and Android devices at minimum).We currently have CheckPoint firewalls (with VPN capabilities, currently unused), SonicWall, and Aventail devices at our disposal, but would not be against adding new equipment if the solution is secure, easy to deploy, and easy to manage.We want to use client certificates for authentication, though we currently have no infrastructure in place for such a thing.I'm looking for starting points/reference documents to learn to deploy:
* Certificate infrastructure, including a secure and manageable way to deploy certificates to devices, and revoke them if devices are lost or stolen.
* VPN concentrator configuration guides (whether it be Cisco or one of our existing VPN-capable devices).
