ISE EAP Authentication fails

I've integrated a new ISE deployment, After a while I start getting the following error below, for wired users, it randomly fails on different users
The NAD I use is WS-C3650-48PD with the following 03.03.03SE cat3k_caa-universalk9 version,
All was working properly for one month, all of a sudden it has started to report such error
I tried to optimize the timers , but it's still the same
Also when I do clear authentication on the same user who has failed the authentication passed
Please advice
Event
5400 Authentication failed
Failure Reason
12953 Received EAP packet from the middle of conversation that contains a session on this PSN that does not exist
Resolution
Verify known NAD issues and published bugs. Verify NAD configuration. Turn debug log on DEBUG level to troubleshoot the problem.
Root cause
Session was not found on this PSN. Possible unexpected NAD behavior. Session belongs to this PSN according to hostname but may has already been reaped by timeout. This packet arrived too late.

IOS-XE has been very problematic. The version of code that you are running is not that old but I would recommend that you upgrade it. I have heard very positive feedback for v.3.7.0 but it is fairly new so if you want to be safe I would suggest running the 3.3.5.

Cisco ISE and Authentication Failed VLAN

I am trying to setup ISE to assign a VLAN to unauthorized computers. I tried using "authentication event fail action authorize vlan 666" command but unfortunately I'm using multi-auth because we have users with bridged VMs and Cisco does not support it (http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_55_se/configuration/guide/sw8021x.html#wp1454875).
Is there a way to make an Authorization/Authentication profile within ISE to assign the VLAN to failed devices?

You can set endpoint protection status to quarantine, and establish policies that assign different
authorization profiles, depending on the status of the endpoint.
Quarantine essentially moves an endpoint from its default VLAN to a specified Quarantine VLAN. The
The Quarantine VLAN must be previously defined by a network administrator and supported on the
same NAS as the endpoint. Unquarantine reverses the quarantine action, returning the endpoint to its
original VLAN.
The quarantine and unquarantine actions are performed as a result of established Authorization Rules
that are defined to check for EPSStatus

Cisco ISE Guest Authentication Failed : 86020: Unknown exception

Hi,
I would like to check what may be causing the error message 86020:unknown exception for ise when guest user authenticates via wireless using CWA? I have also attached a screen capture of the error and after the authenitcation logs change to autheorization only succeed after a repeated trying. Based on user feedback for failed login, When guest user gets conected to wirless and login in to guest portal with credential after putting credential then its again redirect to same login page wihout successful login prompt; not too sure if there may be any settings that may be looked into and the reason for the unknown exception error?
Any suggestion/recommendation is appreciated.

Hi Tarik,
Not too sure if i understand on the static hostname for redirection; there are 2 PSNs for the deployment however they are acting as active/secondary for the wireless (This is done from the wlan on the wlc to set the primary/secondary radius server). From the guest redirection; it is always hitting the primary radius server defined on the wlan/wlc. The ise is running version 1.1.4 with patch 8 applied.
Not too sure if there may be any settings that may be looked into for the guest authentication/redirection and the reason for the unknown exception error?
Thanks.

EAP Authentication Failing (External DB account restriction)

Hi,
I am using ACS 3.0 as my Access Server configured for LEAP authentication,Everything was working fine till 2 days back, All my wireless clients ver getting authenticated,
But suddenly they have stopped doing so, On checking the logs it says "External DB account restriction"
I am using Windows Group Mapping, Dont know why suddenly it has started behaving like this, Have made no changes on the user profiles/permissions from either ACS or windows servers.
Any clue...suggestions..
Thanks
Maneesh

I'm having the same problem and it is quite frustrating... It should not be this difficult.
I've tried both IAS and ACS and I can not get either one of them to work. I'm sure it has something to do with certificates... I just don't know what I'm doing wrong, but I'm going to beat the stuffing out my server if I see "External DB account Restriction" one more time!
currently i'm trying to get ACS 3.2.1(trial) on Win2k SP3 to work and time and time again no matter how I try to install the certificate I create (following instructions in chapter 10 of the User Guide) I keep getting that infernal error. If someone out there could post SPECIFIC instructions about how they got their installation to work it would be GREATLY appreciated.

Cisco ISE authentication failed because client reject certificate

Hi Experts,
I am a newbie in ISE and having problem in my first step in authentication. Please help.
I am trying to deploy a standalone Cisco ISE 1.1.2 with WLC using 802.1x authentication. The user authentication configured to be checked to ISE's internal user database for early deployment. But when the user try to authenticate, they failed with error message in ISE :
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
I've generate a certificate for ISE using Windows Server CA and replace ISE's self-signed certificate with the new certificate but authentication still failed with the same error message. Must I generate a certificate for WLC also? Please help me in solving this problem.

Ratna

Certificate-Based User Authentication via Supplicant Failing
Symptoms or
Issue
User authentication is failing on the client machine, and the user is receiving a

Conditions (This issue occurs with authentication protocols that require certificate validation.)
Possible Authentications report failure reasons:
• “Authentication failed: 11514 Unexpectedly received empty TLS message;
treating as a rejection by the client”
• “Authentication failed: 12153 EAP-FAST failed SSL/TLS handshake because
the client rejected the Cisco ISE local-certificate”

Note This is an indication that the client does not have or does not trust the Cisco
ISE certificates.
Possible Causes The supplicant or client machine is not accepting the certificate from Cisco ISE.
The client machine is configured to validate the server certificate, but is not
configured to trust the Cisco ISE certificate.
Resolution The client machine must accept the Cisco ISE certificate to enable authentication.

ISE Problem: EAP-TLS failed SSL/TLS handshake because of an unknown CA in the client certificates chain

Hello, I´m stucked with this problem for 3 weeks now.
I´m not able to configure the EAP-TLS autentication.
In the "Certificate Store" of the ISE server I have Installed the Root, policy and the Issuing certificates as "trust for client authentication",and in the Local store I have a certificate issuing for the same issuing authority which sign the thw client ones.
The ISE´s certificate has been issued with the "server Authentication certificate" template.
The clients have installed the certificates also the certificate chain.
When I try to authenticate the wireless clients I allways get the same error: " Authentication failed : 12514 EAP-TLS failed SSL/TLS handshake because of an unknown CA in the client certificates chain"
and "OpenSSLErrorMessage=SSL alert
code=0x230=560 ; source=local ; type=fatal ; message="Unknown CA - error self-signed certificate in chain",OpenSSLErrorStack= 1208556432:error:140890B2:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:no certificate returned:s3_srvr.c:2720"
I don´t know what else can I do.
Thank you

Hi Rik,
the Below are the certificate details
ISE Certificate Signed by XX-CA-PROC-06
User PKI Signed by XX-CA-OTHER-08
In ISE certificate Store i have the below certificates
XX-CA-OTHER-08 signed by XX-CA-ROOT-04
XX-CA-PROC-06 signed by XX-CA-ROOT-04
XX-CA-ROOT-04 signed by XX-CA-ROOT-04
ISE certificate signed by XX-CA-PROC-06
I have enabled - 'Trust for client authentication' on all three certificates
this is unchecked - 'Enable Validation of Certificate Extensions (accept only valid certificate)'
when i check the certificates of current user in the Client PC this is how it shows.
XX-CA-ROOT-04 is listed in Trusted root Certification Authority
and XX-CA-PROC-06 and XX-CA-OTHER-08 are in Intermediate Certificate Authorities

Hi guys,
I have root CA and intermediate CA in ISE local certificate store trusted for client authentication.
I have imported both root ca and client certificate in the device I want to authenticate, but ISE keeps spitting out this error :
12520 EAP-TLS failed SSL/TLS handshake because the client rejected the ISE local-certificate

Cisco ISE authentication failed for Win XP SP3

Hello,
I have some trouble this Win XP wired Client authentication. With Win7 everything works well.
ISE 1.2 (patch 4)
Switch: 2960 / 2960S (15.0.(2)SE2)
Authentication details:
Event:
5400 Authentication failed:
Failure Reason
11514 Unexpectedly received empty TLS message; treating as a rejection by the client
Resolution
Ensure that the client's supplicant does not have any known compatibility issues and that it is properly configured. Also ensure that the ISE server certificate is trusted by the client, by configuring the supplicant with the CA certificate that signed the ISE server certificate. It is strongly recommended to not disable the server certificate validation on the client!
Root cause While trying to negotiate a TLS handshake with the client, ISE expected to receive a non-empty TLS message or TLS alert message, but instead received an empty TLS message. This could be due to an inconformity in the implementation of the protocol between ISE and the supplicant. For example, it is a known issue that the XP supplicant sends an empty TLS message instead of a non-empty TLS alert message. It might also involve the supplicant not trusting the ISE server certificate for some reason. ISE treated the unexpected message as a sign that the client rejected the tunnel establishment.
I try to disable validate server certificates on Win XP Clients, but it won´t work for me.
Add ISE self-sign certificate to clients trusted root certification authorities and enable validate server certificates also won´t work.
Any idea?
thanks

The ISE use a self-signed certificate. I add this self-signed certificate to the clients "trusted root certification authorities", enable validate server certificates at the eap properties and select the added certificate from the trust list. But if I uncheck validate server certificates, I see the same error message as well.
Are there any differences between xp client config and win7 client config?
thanks,

ISE Voip phones: authentication failed against AD

the message is
2064 Authentication method is not supported by any applicable identity store(s): Authentication failed
the user is present on AD and testing user in ise is ok
the authentication rule to check in AD is created
policy servers are joined and in green status
if I create an internal user (just for testing) authentication is ok
my authentication sequence is:
mab
mab_ad
dot1x
dot1x_ad
those phones uses eap-md5
i guess there is something to check in AD, can someone help me to solve this?

yes that is true however it supports eap md5 against internal database strange thing...
it won't have been a bad thing if it had the ability to turn over the eap-md5 request in another format like ldap...
thank you!!

EAP-TLS or PEAP authentication failed during SSL handshake

Hi Pros,
I am a newbie in the ACS 4.2 and EAP-TLS implementation, with that being said. I face an issue during a EAP-TLS implementation. My search shows that this kind of error message is already certificate issue;However, I have deleted and recreated the certificate in both ACS and the client with the same result. I have deleted and re-install the certchain as well.
When I check my log in the failed attemps, there is what I found:

In the output below, it says that the user is authenticate and it puts the user in the right group with the right username, but the user never really authenticate. Maybe for the first few seconds when I initiate the connection.
Before I forget, the suppliant is using WIN XP and 802.1x is enable. I even uncheck not verify the server and the ACS under External User Databases, I did check ENABLE EAP-TLS machine authentication.
Thanks in advance for your help,

Any ideas on this guys?? In my end, i've been reading some docs... Things started to make sens to me, but I still cannot authenticate, still the same errors. One more thing that catch my attention now is the time it takes to open a telnet session to cisco device which has the ACS for auth server.
My AD(Active Direct) and the ACS server are local same subnet(server subnet). Ping to the ACS from my desktop which is in different subnet is only take 1ms. To confirm that the issue is the ACS server, I decided to use another server in remote location, the telnet connection is way faster than the local ACS.
Let's brain storm together to figure out this guys.
Thanks in advance,

Eap tls authentication fails if bluetooth device connected

Hi All, I'm new to Macs but was tasked with getting a MacBook Air connected to our AD integrated, 802.1x wifi network. After a lot of trial and error with certificates I finally got this working but now have a rather bizarre problem. With the MBA on it's own it will connect to the wifi network, sucessfully authenticate and work perfectly well. However, if my Apple bluetooth mouse or keyboard are connected to the MBA the EAP-TLS authentication fails. A packet capture of the connection process shows that at the same point every time the process take a while then a packet shows as "Unknown Error Ignored", then loops thorugh the process. Turning off the keybpard and mouse at this point and the MBA will connect. Once connected I can then connect the keyboard and mouse and continue to stay connected for a while before, I assume, the AP forces a re-auth and the connection drops again.
Has anyone come across this elsewhere?
Thanks

I have a Macbook Pro Retina 15" from 2012 and it has the same issue. Running 10.8.4. I have spent probably 5-6 hours trying to troubleshoot cert's network settings, did a complete fresh install (then restored from timemachine when that did not work) with no luck this solution worked but obviously is not a real solution as it should not confilct in this way. Great job on finding a workaround! I will be contacting apple about this ASAP under my applecare.

EAP-TLS & ACE Appliance "EAP-TLS or PEAP authentication failed"

Hello - I have a version 3.2 of the ACS appliance and I am trying to set up a successful test of EAP-TLS. I have a W2K server for a CA and I believe I have the certificate install properly. However, I get the "EAP-TLS or PEAP authentication failed during SSL handshake" error message in my failed attempts log. The troubleshooting document tells me to look at the CSAuth.log file but I can't seem to find in on the ACS Appliance.
Does anyone have any ideas how to troubleshoot this problem with the appliance?

If the client's certificate on the ACS is invalid (which depends on the certificate's valid "from" and "to" dates, the server's date and time settings, and CA trust), then the server will reject it and authentication will fail. The ACS will log the failed authentication in the web interface under Reports and Activity > Failed Attempts > Failed Attempts XXX.csv with the Authentication Failure-Code similar to "EAP-TLS or PEAP authentication failed during SSL handshake." If the ACS rejects the client's certificate because the ACS does not trust the CA, the expected error message in the CSAuth.log file is similar to the following.
AUTH 06/04/2003 15:47:43 E 0345 1696 EAP: ProcessResponse:
SSL handshake failed, status = 3 (SSL alert fatal:unknown CA certificate)If the ACS rejects the client's certificate because the certificate has expired, the expected error message in the CSAuth.log file is similar to the following.
AUTH 06/04/2005 15:02:08 E 0345 1692 EAP: ProcessResponse:
SSL handshake failed, status = 3 (SSL alert fatal:certificate expired)

EAP-TLS or PEAP authentication failed due to unknown CA certificate during SSL handshake

Hi All ,
             I am trying to test EAP_TLS authentication on acs 4.2.1.15 running on Appliance 1120 , I have installed my server certficate along with CA certficate on my appliance box , I have enabled features of EAP_TLS under golbal authentication setup .
             I have downloaded client supplicant certficate file for my windows XP machine .
When i tried to authenticated i am finding following error message under failed attempts(EAP-TLS or PEAP authentication failed due to unknown CA certificate during SSL handshake) on my acs appliance box .
Under certficate revocation list , I have forced my CA as CRL in use . Attached snap shot of all .
Suggest me whether i need to enable all corresponding CA certficate undercertficate trust list , Kindly let me know were i am doing wrong on this ..

Hello,
I am NO expert on certificates but I have seen your error dozens of times from wireless clients on my Cisco ACS 4.2 Radius server.
Through trial and error I wrote up this procedure for our Helpdesk for installing certs in Windows XP and Windows 7. These steps haven't failed me yet and the Helpdesk doesn't bother me as much anymore so see if this helps you:
-          Manually install the Global CA under BOTH Trusted Root Certification Authorities\Certificates AND Intermediate Certification                      Authorities\Certificates
-          Manually install the Intermediate CA under JUST the Intermediate Certification Authorities\Certificates
-          Delete the wireless network from the computer
-          REBOOT!!
-          Open the Microsoft Management Console, “mmc”.
-          Go FILE\Add Remove SnapIn. Select Certificates ..
-          If promoted, do it for “My User Account”.
-          Make sure the certificates are where you put them.
-          If you see any of these exact certificates out of place in either Trusted Root Certification Authorities\Certificates or Intermediate Certification                      Authorities\Certificates, remove them.
-          Redo wireless network setup again
I hope this helps you.

EAP-TLS or PEAP authentication failed during SSL handshake to the ACS serve

We are running the LWAPP (2006 wlc's and 1242 AP's) and using the ACS 4.0 for authentication. Our users are
experiencing an issue, where they are successfully authenticated the first time, however as the number of them is increasing, they're starting to drop the connections and being prompted to re-authenticate. At this point, they are not being able to authenticate again.
We're using PEAP for the authentication and Win XP SP2 clients as the supplicants. The error message that we are seeing on the ACS for that controller is "EAP-TLS or PEAP authentication failed during SSL handshake to the ACS server"...Not sure if this error msg is relevant since we have other WLC's that are working OK and still generating the same error msg on the ACS...
Thanks..

Here are some configs you can try:
config advanced eap identity-request-timeout 120
config advanced eap identity-request-retries 20
config advanced eap request-timeout 120
