Cisco AAA/Identity/Nac :: Wireless ISE - 12508 EAP-TLS Handshake Failed
Mar 21, 2013
I'm in the middle of my very first wireless ISE deployment and I'm hitting issues with EAP-TLS based authentication. In short, all EAP-TLS authentication is failing with the following error. Below that is the relevant excerpt from the logs:
Authentication failed : 12508 EAP-TLS handshake failed
OpenSSLErrorMessage=SSL alert: code=0x233=563 ; source=local ; type=fatal ; message="X509 decrypt error - certificate signature failure", OpenSSLErrorStack= 597863312:error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown

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.

WLC 5508 running 7.0.98.0
Site was running fine until the WLC had a hardware failure.
A new WLC was shipped out, was running 6.0.99 then manually upgraded to 7.0.98. Clients cannot authenticatewith recurrent logs messages like this.

I have a problem where wireless clients at a remote site cannot successfully authenticate through their WLC to my ACS 5.2 (Linux on VM). I have three sites where this authentication is functioning properly; at my fourth site the wireless clients fail with a PEAP error: "12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate". My wireless clients are Win7 using WPA2-Enterprise security type with AES encryption. The authentication method is set to Microsoft PEAP (EAP-MSCHAP v2) and the 'Validate server certificate' is not checked. My wireless access rules on ACS 5.2 are working well at three sites. My ACS 5.2 has a self-signed certificate that doesn't expire until August 2012. A laptop that can successfully authenticate at other sites cannot authenticate at the fourth site.
Phase one of the PEAP process is where the client authenticates the server certificate and the TLS tunnel is created so that in phase two user authentication credentials are sent through the TLS tunnel using EAP. My clients do not seem to be able to create the TLS tunnel because they reject the ACS local certificate; thus, user credentials are never passed and authentication fails. I have renewed the ACS local certificate and rebooted the ACS server but the problem persists. My WLAN on the WLC has its security policy set to [WPA + WPA2][Auth(802.1X)]. WPA uses TKIP and WPA2 uses AES; Auth Key Mgmt is set to 802.1X. The remote site where authentication fails is a different domain; the other three sites are the same domain.
I can see the failed authentication attempts in my ACS "Monitoring and Reports | Reports | Catalog | AAA Protocol | RADIUS Authentication" report. They all fail with the same PEAP error: 12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate. The ACS local certificate works fine at three sites--just not at the fourth. Is my problem the certificate or is it an 802.1X client problem?

I recently purchases new E3000. I setup the E3000 with static IP from border router rather DCHP which seemed to default to the same IP address and DNS. The laptops tied to the E3000 have their own IP's that are different from the IP of the border router. E3000 is configured with no firewall an minimal protection, for now. The reason for minimal protection was to get the handshaking to work between the two routers. The border router is a Verizon product. The old router that I was using is a Netgear that did handshake with the border router. I have the latest firmware for the E3000 namely Firmware version: 1.0.04 build 6. Router will not handshake either with wired or wireless connections. Laptop used to connect to the E3000 is running Windows 7 Ultimate. In fact all laptops here are using the same OS and connect using wireless. I tried the included software package from the website, which housed a diagnostic that apparently couldn't fix the problem as well. I don't have clue as to the reason for E3000 not to handshake with the border router.

I've just had to rebuild my ACS appliance with new hardrives but I am unable to register the devices to each I get a system error. I thought it may have had something to do with the rebuilt device not being joined tothe domain but it has now been joined albeit using a different ad account, but still cannot register to primary.

I have already set up a lab comprising of 1x2950-24 switch, 2x3750-24T in stack mode and 2x MS Domain Controller with AD 2008 Servers and NPS enabled (Domain level 2008). I use NPS as a Radius Server. I am trying to test the 802.1x framework in two scenarios.
1. I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant. As authenticator use the 2950 switch and as authentication servers I use the two NPS integrated in MS DCs. Everything is working fine as I expected with basic configuration guidelines from Cisco & Microsoft.
2. I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant (the same as before). As authenticator I use the 3750 Stack switch and as authentication servers I use the two NPS integrated in MS DCs (the same as before). I have configured the supplicant for both machine or user authentication in both scenarios. However the client never pass the authentication in the second one. I disconnect and connect the same supplicant in the 2950 switch and the authentication is completed successfully. Getting back to the 3750 stack the authentication failed and the laptop gains network access in the configured Auth-Failed Vlan. I have tried several configuration changes without success. I cannot understand why does this happen. I have made some debugs and I am sending them a long with a partial basic configuration of 3750 stack switch.

I´ve implemented 2 Cisco ISE v1.1 in HA to run MAB and 802.x Authentication / Authorization. Using Local ISE DB and Active Directory as an External Identity Source for wireless and wired users and devices. This was working fine 2 weeks ago after finishing installation.
My NAD devices are a Core SW 6500 for wired users (there are no access SW, just the Core for the whole network, its a small office) and a WLC 2405 for Wireless Users.[code].....

I am gettning warning messages in ISE saying
Cause:Dynamic Authorization Failed for Device: 0002SWC003 (switch)Details:Dynamic Authorization Failed
It is not only on that switch but on all switches I have configured. I am using 3560 IPBase 12.2(55)SE6. I have configured them according to Trustsec 2.1. My end devices are none-802.1x. I can't figure out what is causing this error.
The thing is that I have not experienced any problem. In Live Authentications there are some 'Unknown' and 'Profiled' devices hitting the DenyAccess rule, but other then that everying is beeing Authorized fine.

Having an issue where a user will plug a PC into a switch. The switch does a MAB authenticaiton and the MAC is not located in the ACS server. It logs the failed attempt, but when the PC is removed from the switch, the failed attempts keep getting logged until the port is bounced. Any way to keep the attemps from happening after the PC is removed? If not, any way to make it stop without bouncing the port?
running ACS version 5.2.0.26
switch port config:
interface GigabitEthernet1/0/2
sw access vlan 2 sw mode access

I am facing an issue with several ACS appliances (some other work well) when upgrading to version 5.2.0.26.8.
When I launch the command acs patch install, I receive the following error message (we use FTP):
Failed to copy file '5-2-0-26-8.tar.gpg' from repository PatchRepository
(Error -302)
% Error: patch install 5-2-0-26-8.tar.gpg from repository PatchRepository - transfer failed (code 1)
This happens on three appliances but I could successfully upgrade 4 other appliances.
What is the reason behind this error code ? What could I do solve it ? I have already tried to create another repository on another server, without success.

I've got a problem with Cisco ACS 4.2 authenticating Cisco 4710 ACE appliance.
ACS4.2 has been configured to use both internal and external database. It's been working fine for a couple or years.
Recently we bought a Cisco 4710 ACE appliance. When I use ACS4.2 internal username and password to login the Cisco 4710 ACE appliance, I have no problem. I can also see the passed authentication log on ACS4.2. However, if I use AD username and password, I couldn't login in. The message is "Login incorrect". I checked the failed attempts log on the ACS4.2, there was no log regarding the failed attempt. My AD username and password works fine on all other cisco routers and switches.
I've posted my AAA configuration of the 4710 ACE below. ACE is running on the latest version A4(1.1).
tacacs-server key 7 "xxxxxxxxxxxxx"aaa group server tacacs+ tac_admin server xx.xx.xx.xx
aaa authentication login default group tac_admin local aaa authentication login console group tac_admin local aaa accounting default group tac_admin

While working in a 3560 all of a sudden I received the message "command authorization failed" while trying to issue certain commands.
It appears I lost my priv 15 authorization. We have seen this before, we do not have access to the ACS to trouble shoot the issue.I tried logging in a 2nd and 3rd time using tacacs and received the same error whenever I issued a command such as dir flash: , copy tftp flash or show run. At the time I was trying to copy IOS to the switch, I had a co-worker log in and it was fine for him and he completed the copy.
Once completed I logged back in and all was fine again. We suspect an issue with ACS? possibly a timeout of our TACACS authorization ?

I am getting Authorisation requests failed log entries for a user however there aren't any successful authentication logs.
The user would never be able to authenticate as it no longer exists in ACS (it was the user for someone who left the company 3-4 month ago)
The other wierd thing is that the caller-id is 0.0.0.0 BTW the NAS is a Cisco ASA firewall running 8.0(3)

Just upgraded from 4.0 - to 4.2 then to 4.2.1 15. As you may have seen with periovous posts of mine its not been an esay ride.I have now managed to get it all working - backups AAA etc but for some reason i cannot get the replication to work! Its states the following...
Within the Database Replication active log - Error OutBound database replication failed - refer to CSAuth log file.Other lines in the log state its ok eg - Component logging reports was updated - being replicated to slave...
Please note that the $ is a symbol that i have used because the symbol in the log is strange and i cannot seem to be able replicate here with this text, for example $etworks - should be networks.

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.

I am using ISE 1.1.1.268 and WLC 7.2.111.3 and NAC agent version 4.9.1.6 on Windows 7 Client machines.
About once a day i get the error "ISE Alarm (WARNING): Dynamic Authorization Failed for Device".
The device it is referring to is my NAD, a WLC 5508 running 7.2.111.3
I have looked at the logs and I cannot see anything in the logs which corresponds to this message so that I can troubleshoot further. Maybe I can if I am enabling the correct logging level on the correct ISE component.
What are the components and the logging level that I should set to get some more detail about this error?
At the moment, I have only set debug logging on Active Directory. I have TRACE logging set on Posture, Run time AAA & prrt-JNI.
I do not want to enable too much debug logs, so what is the specific element that I should be debugging.
I thought debugging the posture element would be enough but when I look at the logs there is nothing there that relates to this message.

I'm working on implementing a RADIUS authentication for wireless access with the following :
- PCs running Windows 7, protocol used is PEAP (without validating the server certificate to make it simple at first),
- AP 1252 configured to use a RADIUS server to authenticate (it's working good with an ACS server 4.2),
- ACS Server 5.1.0.44.5 running as VM connected to an AD domain and working good with VPN connections,
- AD domain running on Windows 2003 Server.
My ACS VM is working good since a couple of months for VPN (RADIUS) and administration (TACACS) remote access, both using Active Directory. Now, I'd like to use it to authenticate people connecting to a 1252 Cisco access point but I'm getting this error "24427 Access to Active Directory failed". I switched from PEAP to LEAP but this is the same.

There is ASA with remote access VPN and users are authenticated using third party signed certificates (CA is not local in ASA).When user certificate expires i can see it in syslog messages. For example:
%ASA-3-717009: Certificate validation failed. Certificate date is out-of-range, serial number: (...)
I would like to know if there is an opportunity to view user's certificate expiry date beforehand, say, 3 days before?
