Is it possible to strip suffix on wireless client running PEAP (MS-CHAPv2). ACS version 5.3 (patch 5) - 5-3-0-40-5
Look like ACS 5.1 does not support this - see below link [URL]
We have just set up a Secure ACS 5.2 VM to provide authentication for Anyconnect VPN clients. The clients connect to an ASA 5520, which queries the ACS, which in turn queries Active Directory directly. All seemed to work OK, but I noticed it was using PAP. Following some docs, MS-CHAPv2 was enabled via the "Password-management" command. This broke the configuration and the error on the ACS was:
11309 Incorrect RADIUS MS-CHAP v2 attribute Some references suggest that the ASA and ACS should talk MSCHAPv2 without additional config, so I guess it must be the ASA config for the tunnel-group. There are additional secondary authentication and authorisation pages on ASDM, that I suspect might be necessary to use mschap.
I have configure my ACS 5.3 to strip the prefix of the radius username (Domain week wang) it received and I also configured my ACS as the External Radius Server. However, this does not seem to work. The authentication protocol that I am using is PEAP Mschap v2.
I have read inside this forum that due to the fact that the radius username and password is transited inside the TLS tunnel of the PEAP MsChap v2 thus ACS is not able to do the stripping as it is not allow to touch anything inside the TLS tunnel.
i have flushed dns cache and i do not know how to renew dns suffix.

I've checked the release notes for 5.3.0.40.5 and there are some changes/fixes for AD but nothing I can see to explain the behaviour above. I'm looking to upgrade to 5.3.0.40.5 soon but I really need the Alternate UPN suffixes to work.mydomain.com is the AD domain namean Alternate UPN suffix of another.com has been added to AD
A valid AD user can add either the @mydomain.com or the @another.com suffixes to their username and login successfully. This works fine with 5.3.0.40.2 but changes when I upgrade to 5.3.0.40.5 - users who use the @mydomain.com login ok but users using the Alternate UPN @another.com fail with the error: [code]
For awhile every now and then my computer decides it needs to 'acquire network address' on booting up. It never does succeed unless prompted by my going into Wireless Connections and pressing 'repair'. Yet my connection to the Internet is not impeded even while the little yellow ball hovers round mini monitor in the taskbar. It is hovering now as this thread is written. ipconfig reveals Connection Specific DNS suffix is missing, but the IP Address is there. My ZyXel 7087 router shows a fixed W/LAN/WPS and DSL light, but the Internet light is continually flickering, regardless of whether the computer is on. The TCP/IP is set to,'Obtain an IP address automatically' and 'Obtain DNS server address automatically'. Advanced TCP/IP Settings shows DHCP Enabled. DNS tab - DNS server addresses box is blank 'Append primary and connection specific DNS suffixes' is dotted and 'Append parent suffixes of the primary suffix' is ticked. 'Append these DNS suffixes (in order)' is unchecked. WINS addresses box is blank. 'Enable LMHOSTS lookup' is ticked. NetBIOS setting - Default (checked) - Use NetBIOS setting from the DHCP server. If static IP address is used or the DHCP server does not provide NetBIOS setting enable NetBIOS over TCP/IP. Enable & Disable NetBIOS over TCP/IP unchecked. While reading the WNC status the computer has found the Network address, but all above remains true.

Since I did not have the password I performed a hard reset.Now when I try to acces any website I receive error 105 ERR_ NAME_ NOT_RESOLVEDThe only difference that I can see now is that there is no longer a connection specific DNS suffix assigned.Could this be the issue? If yes how can I configure this?

I assume it's a wap problem since all of my wired clients receive the correct suffix. I'm using a RVS4000 router if that makes any difference.

I was able to successfully implement MS-PEAP authentication with 5508 WLAN controllers and Cisco ACS v4.2. However, when I integrated 4402 WLC with version code 7.0.116, it did not pass across any authentication requests. Did a debug aaa events enable and there was no output. Configured another SSSID with PSK to test that my controller was OK and aaa debug was working, and there were CLI messages when I associated an AP.
why the 4402 is not working as I have compared configs with the 5508 and there is no difference. The shared secret is configured on both ACS and Controller and CA is downloaded on the ACS.
I was pondering on getting a certificate fro ma public CA to maintain easier configuration for end users. There will be a multitude of devices on this wireless network configured with 802.1x PEAP. (iPhones, iPADs, Droids, and PC's of course).
If you were to get a certificate from a public CA, I'm assuming this would be just a regular server certificate from GoDaddy, or Verisgn?
I have 802.1x/peap authentication in my wireless network with ACS 4.2 as the authentication server. I enabled PEAP machine authentication under the Unknown user policy --->database configuration sub-menu. I discovered that I was still able to access the wireless network on my android phone with my domain logon. I later discovered that there is an option in Group policy to force Windows XP clients to perform computer authentication. Now the problem is that windows 7 clients do not have the EAPOL option in the registry, hence the group policy object may not work. How to enforce machine authentication and stop unwanted devices without having to purchase a NAC server.

I have configured ACS 5.1 to check AD domain computer accounts then permit access, the next rule authenticates AD domain users and checks machine accounts with WAS MACHINE AUTHENTICATED "TRUE" permit.
My dilemma - Windows XP supplicant work fine and I can see the host/machine (Wireless device) authenticating followed by user credentials, but when I use the Intel Pro/set supplicant version 12.1 the same device fails authentication due to ACS not being able to verify a good previous machine authentication?
Is this problem ACS related or down to the Intel supplicant.
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.
A customer has RADIUS running on a Win Server 2008 R2 machine, has Autonomous 1140 APs and a mix of Windows 7 and XP Pro clients. Using PEAP as the authentication method the Win 7 clients can access the WLAN, but the Win XP clients cannot. The Win XP clients are at least SP2. I am doing some research before going to site on Friday and wanted to poll the community. I found an older post speaking to a MS Hotfix under KB#885453, but it referes to "third-party RADIUS servers," not MS servers URL.

View 1 Replies View RelatedI 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.
Any good guide for configuring PEAP with Machine Authentication to allow for domain login?This is a clean install on a new 5.2 install.We are moving from 4.X to 5.2 and i want to make sure i dont miss anything.

View 3 Replies View RelatedI'm in the process of setting up PEAP with ACS 5. From understanding the certificate that I generate is a server side certificate used between ACS and CA authority. However, according to the Cisco document that I'm using it sounds like I still have to install a certificate on the wireless clients that validate the server certificate. Is there a process to push this cert out via AD or do I need to manually install it and if I wanted can I get away with out checking the validate the server certificate on the wireless client?
View 4 Replies View RelatedWe currently are using a self-signed cert (for PEAP machine authentication) that was created on an ACS 3.3 appliance. That cert was manually installed on our laptops when they were configured for wireless conenctivity.My problem is, that self-signed cert will soon be expiring and I am not sure what needs to be done to issue a new cert AND deploy it to my Windows XP Pro clients without a service interruption. If possible, I'd like to leverage our exsiting AD infrastructure for this, but I need some direction, and time is of the essence!!
View 2 Replies View Relatedwe have acs 4.2 as our radius server, and 2 wlc 4404 with a wism2 for our wireless network. we have 2 SSID network, lets call them SSID A and B. A have a more restricted access to server than B.PEAP machine authentification is authorize on both network, to let our users laptop connect before the user login, this enable us to have our computer gpo deploy before the user logon, or have network access to authenticate a user to our directory if he had not logon previously on the laptop.
Users from group A can't logon to SSID B, they can only logon to SSID A, but we have some clever users from group A who have change they wireless setting to only send machine authentification (this can be done in the advance setting of a wireless network in windows 7) to connect to SSID B
We can't force the wireless config by GPO because we don't have an ad 2008 domain, we are still in 2003 soo we can't change the gpo for windows 7 wireless setting . I can't force user to require machine authentification and user authentification because we have a lot of ipad and iphone, and other mobile device that connect using only their user credentials.Is there a way I could configure this without having to disable machine authentification for SSID B?
I'm running version 7.2.111.3 on my WLC 5508 and I try to figure out how I can set PEAP towards my configurerd Radius servers. On my Local EAP profile I can specify PEAP, but how is it default configurerd when you just specify the radius servers on the "WLANs > Edit Test > security > AAA servers tab ?
The MS radius logs tell me that it is EAP and not PEAP, so the questions is does the WLC support Microsoft: Protected EAP ???

Cisco 5508 wireless controllerCisco ACS 5.1LDAP connection I have setup the wireless controller to do RADUIS authentication with the ACS 5.1 using LDAP. The setup is currently working, Brief info below on setup.
I setup the PC client to use WPA2-Enterprise AES and authentication method CISCO PEAP. When I connect to the SSID this will prompt for a username and password. I will enter in my AD details and the ACS with the LDAP connection will authenicate and on the network I go.
Now I want to add machine authentication with CERTIFICATES, each laptop and pc in our network has CA certificates installed.
way that I can add these certificates into the ACS 5.1 so I pretty much want to import them into the ACS. Once they are imported inside I want the ACS to check that the certificates are on the PC and then prompt for the AD username and password, and only once it meets these two conditions it allows the workstation onto the network.So it will be a two form authentication one with certificates and the other ldap.
I have a Cisco WLC talking to a ACS 4400 version 5.1 which in turn talks to Active Directory.Ive been trying to get 802.1x for wireless clients going, I have a cert on the ACS from verisign on the box but when users try to sign in they get 12309 PEAP handshake failed in the ACS RADIUS log.The cert was exported and placed directly on the testing laptop and at one point it all worked. I stepped away from it for 2 weeks to get a new internal CA built on a windows box, now coming back to it with the intent of issuing new certs to the ACS from the internal CA and thought I would check it to make sure all was good, but its not.Google doesn’t return happy results for “12309 PEAP handshake failed”, I opened a TAC case on it and they took my cert to their lab. Haven’t heard back.

I bought 2 Cisco 1140 series Access Points a couple of months ago. We would like to use PEAP to autheticate with Microsoft IAS Radius Server & Active directory. I cannot find a document which describes how to setup this type of configuration. The only document which is close is how to setup LEAP & with ACS: [URL] I initially followed the 'TechReplublic's Ultimate Guide to Enterprise Wireless LAN Security' which has all the steps to setup Radius server, client side configuration, Certificates and finally a handy excel script to generate a config for the AP. This did not work. [URL] I am now trying to configure the AP using the Web GUI. I can see the network on the client machine but when I try to connect it timesout.

I would like to use ISE for authentication. I would like to use PEAP with Server side Cert (similar setup like IAS). I want ISE to perform the same function in addition to profiling etc.....
I was able to integrate ISE with Active Directory but could not get it working with PEAP (server side Cert). I would also like to know if they used Microsoft’s CA server or Open SSL CA server or a third party CA server (Go Daddy, VeriSign etc.)Can you we ISE as a CA server just the way we used Microsoft’s IAS Server as a CA Server?
I replaced an ACS certificate that had been installed as follows:
1. Generate CSR file and private key file, then send CSR to GeoTrust (Key length: 2048 and Digest to sign with SHA1)
2. GeoTrust send me a certificate. Issued by "GeoTrust SSL CA".
3. Install the certificate on the ACS. Restart ACS service.
4. ACS Certification authority setup. Issued by "VeriSign Class 2 Public Primary Certification Authority - G3"
5. Edit certificate trust list and select "VeriSign Class 2 Public Primary Certification Authority - G3" as trusted.
6. Enable EAP-TLS, then restarted the ACS service. The problem is when i try to enable EAP i get the error msg:Failed to initialize PEAP or EAP-TLS authentication protocol because CA certificate is not installed. Install the CA certificate using "ACS Certification Authority Setup" page.I searched on cisco and it said to disable the CSA, but in fact there is no CSA installed on this server.

We are deploying ACS 5.2 to replace our ACS 4.2 in production. I have two wireless networks setup as WPA2-Enterprise. One points at the ACS 4.2 and the other at the ACS 5.2. Both use the same SSL certificate with the same CN. Both authenticate Windows 7 clients. However, Windows 8 CP will only authenticate to the ACS 4.2 and not to ACS 5.2. The error it gives is:
11051 Radius packet contains invalid state attribute
It also shows no authentication method (most of the time).
Occasionally, I get a request that actually shows an authentication method of PEAP (EAP-MSCHAPv2) which is what it should be. On those requests, I get error:
24444 Active Directory operation has failed because of an unspecified error in the ACS.
Both ACs 4.2 and ACS 5.2 are pointed at the same Windows AD source.
