  How does * (certificate-based authentication) work?

  We do * in a company whose phones android and exchange 2010.

  We use the activesync to talk to Exchange via the SSL protocol.

  It works.

  I am documenting HOW it works (on a rather high level).

  I have some information, but would like to know what happens when exchange Gets the customer real auth cert of the device in the last part of the authentication process.

  Exchanges with impatience in its entirety to RFA, since AD (or its related PKI service) created the cert?

  Thank you.

• ACS 5.3 certificate based access to the network by using AD

  Hello

  Is that what someone has implemented certificate based 802. 1 x network access using ACS5.3 & identity authentication outdoor store like AD.

  If yes then please let me know as soon as possible.

  Ajay

  When you use EAP - TLS AD may come into play in one of two ways

  -There is an option to perform a binary comparison on the certificate of the client against a stored in AD (or LDAP)

  -It is possible to retrieve ad for the user groups and use this in authorzation

  Configuration for this is done as follows:

  (1) establish a profile of certificate authentication:

  Users and identity stores > profile of certificate authentication

  In the profile to define the "main Username attribute" - attribute that identifies the user

  Can optionally select "Perform with certificate certificate binary comparison comes from LDAP or Active Directory"

  (2) if want to do authorization based on groups of ads, then need to create a sequence identity

  Users and identity stores > sequence identity store

  In 'List of authentication method' select 'Certificate based' and select the profile of step 1

  In "Attribute retrieval research additional list", select Active Directory in the list of selected stores

  (3) select the sequence of the identity as the result of identity politics. For example, for the strategy set by default:

  Access policies > access > by default access to network > identity

• Certificate of ISE chain is not the confidence of Clients WLAN

  We run ISE 1.1.3 using Entrust cert signed by Entrust sub CA L1C, which is signed by Entrust.net 2048, which is in all the major BONES stores in the approved form (Windows, Android, iOS).

  We have installed a file PEM concatenated with all certificates in the chain, as shown in the records of ISE. The ISE GUI shows all certificates in the chain individually after importation (i.e. the chain works and is good). However, we are not sure if the ISE sends the entire chain to WLAN clients during the EAP authentication or just the ISE cert due to the error message we get on client all types that stipulate that the certifiicate is unreliable.

  So the question is if the ISE really sends the entire chain or just his own cert with the rest of the cert in the string (which would explain why the WLAN clients complain related to approval of certificate.)

  Anyone out there know if the ISE code isn't up to the shipment in the chain of certs in version 1.1.3 yet or if there is an explanation? Screenshot attached of the iPhone to request verification of cert.

  Hello

  I'm having the same problem with ISE 1.1.1 and I have discussed this thing with Cisco (Expert ISE) and he suggested that the best practice is to use the single certifiacte device and then download intermediate root certificate and certificate root in the ISE certificate store. The ISE will send to the full certificate chain - device > mid-range > root. But the problem is with Apple iOS even when the root signature is already approved, it will ALWAYS ask certificate known either accepted. When I use Windows, it works very well what this means that ISE sends the entire string. For Windows, you must explicitly trust CA under the wireless profile properties > Security > Micrsoft PEAP > settings > validate the server certificate, and then select your CA server.

  I always find out why iOS not accepting is not the string and we find some related discussion on the apple support forum. I'll put you on this.

  I hope this helps.

  Unfortunately, as you have understood well enough already, XAuth is enabled at the global level, not by group. If you turn it on for some users, it gets turned on for all, no way around it.

• How to fill a control ring with chains [] array?

  How to fill a control ring with chains [] array?

  It must be karma. (Try really bad karma because I couldn't post this question in my original)

  I must have been a Really bad guy in a previous life...  It's not like I'm bad in this one...

  So... what I want to do this time around?  Something that I thought would be easy... Well... it's a long story...  I had a simple solution, but the client wants something else.  -sigh-

  Here is what they want...  They want a control that allows for multiple selections to a control of the ring (or a control that allows a drop down selection menu).  Bites are filled at run time because it is based on 10 000 other precedents of things this particular choice.  So it must be dynamic.

  The snippet of code & images below show what I'm doing a little...

  The bottom image shows on the right bites which is filled in the control of the ring.  Since the number of items / items changes, I didn't have a bunch of controls stacked on another.  In addition, I have to deal with an unknown quantity of selections.

  Does anyone have a solution that can be recommended?  If so, can you share the solution / idea?

  Thank you

  I have posted a code that does something similar here: http://forums.ni.com/t5/LabVIEW/array-of-cluster/m-p/1822451#M625032

  It uses a table hint and individual controls that are moved on top of the table and populated as needed.  This approach might work for you?  You would need a two-column table and only control ring, which you would fill properly whenever the currently active cell changes.

• 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.

• Dynamic to static IPSec with certificate-based authentication

  I'm trying to implement a dynamic to static LAN2LAN vpn from an ASA 5505 (with a dynamic IP address) to an ASA5520 (with a static IP address)
  I wish I had a small (/ 30) network on the side dynamics which I can connect to a larger (/ 24) network on the static side.
  I also try to use the identity for authentication certificates.

  I produced a root and intermediate CA signed of the intermediate CA with the certificate authority root and then created identity cases for
  the ASAs, signed with the intermediate CA using OpenSSL and imported to a trustpoint

  I tried to use the instructions on:
  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080930f21.shtml
  to configure certificates (replacing MS with OpenSSL) and following the instructions to:

  I tried the ASDM to set up the cert to identity appropriate on the external interface
  [Configuration-> Device Management-> advanced-> SSL settings]

  and establish a connection profile [Configuration-> Device Management-> connection profiles] on both devices,
  setting the part that gets its IP via DHCP static and the side that has the IP permanently to accept dynamic.

  I apply the settings, and nothing happens.

  See the crypto isakmp just returns "there is none its isakmp.

  I don't know where to start debugging it. How can I force the side DHCP to initiate a connection?

  We are sure that both peers are using the same isakmp settings? It seems the policy that uses rsa - sig on one end uses a different Diffie-Hellman group.

• issue certificates of 802. 1 x authentication and X 509

  Hello

  Can someone please help me with the following question:

  First off I am a guy from Windows Server/PKI/AD etc. rather than CISCO, even if I have a CCNA :)

  I take care of PKI to my company and will work with the team CISCO that are the introduction of CISCO's ISE, we will use X 509 CERT on the suppliants (desktop/laptops Windows computers mainly)

  What I want to know is something pretty basic, but I saw not written anywhere

  Question 1:

  First stop, I guess it's the AAA (ISE) server is the entity that verifies the pleading certificate X 509, rather than the AP (access wireless router for example point)? is that correct

  Question 2:

  As supplicants X 509 certificate is public (for example, it is not secure and anyone can ask what it is normal) I guess the AAA server must encrypt a (random number for example) value with the public key of supplicants (of the X 509 cert) then send this value to the supplicant by which the supplicant decrypts with its private key (that no one else has as usual). Then the supplicant figure the value even with servers AAA public key (which is held in servers announced AAA X 509 cert) cela send on the AAA server and once that deciphers AAA server (with its private key) if the value matches the value originally sent to the supplicant then the AAA server can continue with authentication etc.

  The above assumption is correct?

  If the above is correct, not ISE always act like that or can you lower the security and get just the ISE server to check whether he trusts the issuer of the certificate (CRL does OK) the pleading X 509 Cert and not bother to send the encrypted packet as described above (this of course would ensure not begging-1 is actually "supplicant" - 1).

  Thank you very much in advance

  Answers:

  1 - Yes, ISE verifies the certificate presented by the device of end-user (begging) against his PB of authority certificate TRUSTED internal to import in ISE root and intermediary certificates where you use CA non-public servers (this is my case for EAP - TLS) such as Verisign, Entrust, etc. UNFORTUNATELY, ISE allows you only to have 1 cert for the use of EAP in the list (PEAP, EAP - TLS, etc.), which means that you CAN not EAP - TLS and PEAP running on different SSID. The problem is now that Entrust for example use an intermediary called L1K Entrust which is not included in trust for the devices Apple and Win 7 CA. This causes a certificate not approved for IPADs warning then you need to trust this certificate but for Win 7 features the PEAP TLS Tunnel, Setup will fail if the connection cannot be established if you uncheck "VALIDATE SERVER" on Win 7 for this SSID profile.

  2 - you can create a condition that validates the issuer cert but the authorized Protocol is EAP - TLS or PEAP so that the actual process for one of these protocols, based on my understanding is actually. For example, Protocol PEAP, the configuration of the TLS Tunnel is the 1st step, so once the configured secure tunnel then the inside MSChapv2 + EAPOL is performed and finally the data passes through the tunnel

• Cannot delete root a certificate manually with certmgr.

  We are in the processing of the deployment of 802. 1 x throughout the organization. All of the client computers Windows XP SP3 and they are joined to the new Active Directory domain during the migration of the network. (Existing infrastructure is based on Novell NDS, which is being migrated) A GPO has been created in the pub for the 802. 1 x settings and a certification authority root of Thawte primary for all Client computers.

  During the pilot process, we found that there are already two certificates in many machines trusted Local Machine CA root roots of primary Thawte in the store & a Thawte SSL in primary root (which is supposed to be at intermediate CA) it's originally 802. 1 x authentication problem because the GPO does not overwrite these certificates.  Once I have manually remove defective CERT & reapply the GPO, the machine works fine for authentication of 802. 1 x.

  Now to avoid production problems, it is imperative to clean the machines for existing thawte certificates and get applied Group Policy, like machines to join the domain. This cant be done manually because we have more than 1500 workstations.

  Here is the command I tried with the answer.

  certmgr - del - c s root - sha1 91c6d6ee3e8ac86384e548c299295c756c817b81

  Error: Could not delete certificates
  CertMgr failed

  Try to delete the certificate with the certificate number also led to the same result.

  Please advice on how to proceed.

• Renewal of certificates Cisco ISE Admin and EAP

  Hi on board,

  Maybe I'm asking a rather stupid question here, but anyway :)

  Currently, I think about how renew a certificate admin/EAP on a node of the ISE and the effect on the endpoint authentication.

  Here's the thing that I do when I install initially an ISE node

  1.) creation of CSR on ISE (PAN) - CN = $FQDN$ and SAN = 'name of FQDN as well. "

  2.) sign CSR and certificate of bind on the ISE node - done

  Now, after 10 months or two (if the certificate is valid for one year) I want to renew the certificate of admin/EAP ISE.

  Creation of CSR: I can't use the $FQDN$ like CN, because there is still the current certificate (CN must be unique in the store, right?)

  So what to do now? I really need to create a temporary SSC and make the admin/EAP certificate, remove the current certificate, and then create a new CSR? There must be a way better and more important to do nondisruptive.

  How you guys do this in your deployments?

  Thanks again in advance, and sorry if this is a silly question.

  Johannes

  You can install a new certificate on the ISE until he's active, Cisco recommends to install the new certificate before the expiry of the old certificate. This period of overlap between the former certificate expiration date and the new certificate start date gives you time to renew certificates and to plan their installation with little or no downtime. Once the new certificate enters its valid date range, select the EAP or HTTPS protocol. Remember, if you turn on HTTPS, there will be a restart of the service

• Cisco ACS with external DB - EAP - TLS

  Hi guys,.

  I understand how the EAP - TLS exchange works (I think), but if I have a client (with or without wire) that uses EAP - TLS with a CBS, I confirm the following.

  Let both users and computer certificates are used:

  1. customer and ACS are with each of the other automatic certificates to ensure they are known to each other. The eap - tls Exchange.

  2A. At any given time and I'm assuming until the successful eap - tls message is sent to the client, the ACS to check if the user name or computer name is in the AD database?

  2B. Wot is the parameter that is checked on the AD database?

  I read here that it can be: http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/configuration/guide/peap_tls.html#wp999517

  Client certificates

  The client certificates are used to identify with certainty the user in EAP - TLS. They have no role in the construction of the TLS tunnel and are not used for encryption. A positive identification is made by one of three ways:

  CN (or name) comparison-compare CN in the certificate with the user name in the database. More information on this type of comparison is included in the description of the subject field of the certificate.

  Comparison of SAN-compare the San in the certificate with the user name in the database. It is only supported from the ACS 3.2. More information on this type of comparison is included in the description of the field another name of the subject of the certificate.

  Binary comparison - compare the certificate with a binary copy of the certificate stored in the database (only AD and LDAP for that). If you use the binary comparison of certificate, you must store the user certificate in a binary format. Also, for the generic LDAP and Active Directory, the attribute that stores the certificate must be the standard LDAP attribute named "usercertificate".

  3. with the foregoing, if options 1 or 2 are used (CN or SAN comparison), I guess it's just a check between a value out the CERT of the ACS and checked with AD, is that correct? With option 3, GBA exercise a complete comparison of the certificate between what the client and a "cert stored client" on the AD DB?

  Please can someone help me with these points.

  I'm so lost in this kind of things :)) I think.

  Thx a lot and best regards,

• Problem with the two factor authentication with Apple TV.

  I tried to connect to my Apple TV (2nd generation, operating system and updates are up-to-date), log-in failed and indicated that I had to use two-factor authentication which I recently install on my trust Apple devices which included my iMac, iPhone and iPad. As expected, I received a notice on my Apple devices trust with the verification code to six figures to add this code to six figures at the end of my password when signing in the Apple TV. I put my password and add the code check digit at the end on my password. It did not work. Now I can not connect. Any suggestions to connect to Apple TV using 2nd generation two-factor authentication? This Apple TV device is not supported?

  There is model of Apple TV MC572LL/A with Apple TV software version 6.2.1

  Model identifier is AppleTV2, 1

  Model number is A1378

  People have been facing difficulties with this process. I have not encountered such difficulties then have not had the opportunity to test solutions. While a little pain can I suggest that you disable temporarily two authentication step until you have set up your Apple TV.
