I want to use a different certificate by connection profile. Is-it possible on ASA 8.4 ?
My first certificate is for vpn.itcom.fr associated to one connection profile and my second is for vpn.newitcom.fr associated to a second connection profile.
I'm working on task to update the SSL certificate for an application. steps to upgrade the SSL, stuffs need to be checked before and after the installation and how to verify the new certificates.
View 1 Replies View RelatedI'm generally pretty good with VPN issues and with SSL certs, but this is my first rodeo with VPN and certificates together. I've got a Cisco 2811 router running IOS Firewall (12.4(25)) and for a while now, I've had VPN clients connecting using PSK's and XAUTH. In order to tighten security, we'd like to move away from PSK's with Aggressive Mode and use certificates with Main Mode.I've been trying to use the Cisco 2811 as the CA, rather than use a Microsoft server or third-party provider. I think I'm pretty close to getting this to work, but something isn't quite right. My VPN client software does connect to the 2811, and I get prompted for the XAUTH creds. If I supply the right creds, I do see in my VPN log window that I've gotten assigned an IP address from the inside VPN pool, my split tunneling rules come through, but the VPN disconnects almost immediately and I never get a chance to try any pings or to send any other types of traffic. [code]
I have attached a sterilized copy of the 2811's current config (2811_sterile.txt), a copy of the 2811's debug output when the VPN client tries to connect (vpn_client_connect_sterile.txt), and a copy of the VPN client's log with IKE on High and Certificates on High (vpn_log_sterile.txt).FWIW, the 2811 is NOT behind NAT, but my VPN client IS behind NAT. However, I have tried using a direct connection with the VPN client and it didn't seem to change much so I'm not convinced this is a NAT issue.Again, I've never used a Cisco router as a CA and I've been battling this problem for several hours now so the 2811's config may have a lot of unneccessary lines in it at this point.
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?
My ASA's have the follwing Versions: ASA Version 8.4(3) ASDM Version 6.4(7)Have I a chance to configure a site-to-site tunnel with a hostname as peer address when I will use Identity and CA Certificates?

Why the key usage is invalid? What certificate template must be used in MS CA in order to get a regular key usage?
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.
Which certificates do I install on the ASA 5510 ???
I have a Trust External CA Root, Trust Server CA, Extended Validation Secure Server CA and the name of the domain all ending in CRT. Yet the instructions only refer to two certificates ?
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?
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).
Has anyone tried to get two factor authentication working with the asa 5505. I have a CA setup and the enrollment emails are being sent out. But when I go to login to the enrollment site at [URL]. I get a page not found.
I would like to have one factor be a username and password and the second factor being a certificate on the device.
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 issues connecting to the webvpn as its asking for some certificate for authentication, I am using the self generated certificate, but when I try to connect to SSL gateway via its IP address , Browser expect me to provide the certificated, I want to tell the Browser to use the self generated certificate of ASA5505, but not sure how I do it.I undestand when WEBVPN/SSL clientless VPN try to establish the VPN , ASA sends the certificate back to the browser to accept/authenticate it, but when I connect I don't get any certificate where I say YES to accept it.Can I just disable certificate with SSL and just use username/password to crater a WEBVPN ?

I have some questions about the size of the certifcates in ACE module (ACE20). Reading the following link: [URL]
I can verify this text: 4096 (high security, level 4) - For software release A2(2.4) and later in the ACE module and software release A3(2.6) and later in the ACE appliance, you can use 4096-bit SSL certificates in chaingroups and authgroups. You can also import public certificates and keys that are 4096 bits in length.
We intend to use a certificate (CA) with keys of 4096 bits and according to the text of wiki, it's possible.
But if I check the guide [URL]
Somebody that already use certificates with 4096 bits in ACE20 module?

View 8 Replies View RelatedI have a Cisco ASA 5505 as a BOVPN endpoint using certificates. The config is complete and I now need to back it up and restore to a cold standby Cisco ASA 5505 that will sit on the shelf until something goes wrong.
Problem is I cannot restore my certifcates to the standby.
I have tried the backup and restore wizard in ASDM and to be honest it didn't work.
Recently we updated to the Anyconnect 3.0 client. I see the new 3.1 client is out and we are currently testing it for production. My question though is since updating to 3.0 our end users receive a message at the bottom of their client stating "No valid certificates available for authentication" They can still VPN in since we dont do certificate based authentication but we have been getting tons of questions on this. I would like to stop these messages from appearing and I am not sure if its just how the new client behaves or if its something configured on our ASA's.
View 1 Replies View RelatedWhen 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.
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?
View 2 Replies View RelatedA 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.
Does changing the device certificate for AnyConnect Connection Profiles break any established AnyConnect connections, or is it transparent to the users?

I ordered a certificate from Geotrust. Geotrust signed my certificate with an intermediate certificate.

"ERROR: Failed to parse or verify imported ceritificate"
I do not know the way how to add two authentication certificate on ASA. I need similar solution like this: [URL]
So the question how to arrange the installed certificates into chain on Cisco ASA.
My firewall frimware/type is: Cisco Adaptive Security Appliance Software Version 8.3(2)
Hardware: ASA5520, 2048 MB RAM, CPU Pentium 4 Celeron 2000 MHz
One is the FQDN.crt for my domain and the other is the intermediate certificate that is responsible for completing the chain of trust. However, I haven't been successful with installing the intermediate .crt onto my ISA550. I was able to install the FQDN.crt using the guide here: url... but that doesn't talk about installing chained certificates at all.
I have seen some guides talking about how to do this with ASA devices but it seems those don't apply to the ISA. This is mostly because there is no CLI with the ISA (as there is with the ASA) and also I don't see way to import/export private SSL keys from/to the ISA.
