WLC log RADIUS server failed to respond to request

I'm keep on getting same couple MACs being failed. I was hoping somebody has more inside about this? Radius server is pingable from WLC. People are authenticating. Please let me know what log should I provide. Thank you in advance.

You should look at the ACS logs as that will give you a better idea of the failure.

Explanation RADIUS server failed to respond to request for STA

Hi all,
i have configured WLC 5508 to access through FreeRadius. Login is working fine but i see a lot of Warning message like :
WLC_5508_SECONDARY: *radiusTransportThread: #AAA-4-RADIUS_RESPONSE_FAILED: radius_db.c:472 RADIUS server X.X.X.X:X failed to respond to request(ID 28) for STA 40:83:de:3e:ee:81 / user '4083de3eee81'
In Cisco System Message i've found :

Recommended Action No action is required.
Is there a solution?
Thanks

I think you've not configured the WLC as a RADIUS client on the RADIUS server, or the RADIUS shared secret is incorrect.

Radius server occasionally sees attempts from user "XXZZYY"

Osvaldo,
Your observation is correct and this should be documented on the WLC help tab if you search for keyword network user under radius auth.

safari cannot open the page as the server fails to respond? i am getting this message and safari is not working

My 2nd gen works fine with WPA2 and AES encryption.
You may need to go back and start over. Reset the router back to factory defaults, log on as the admin, set up security, DHCP, and make sure the IP address pool has enough IP addresses to lease to ALL of the computers/devices that will connect to that the router.

what is the authentication list precedence for radius authentication?

global list       network user uncheck
i have 3 radius server, 2 of which are use for gloabl authentication(all ap are hreap) and a 3rd one use only for 1 site, when the 2 first radius server fails the wlc use the 3rd one, but the 3rd only has database for 1 site users,
do i need to uncheck the network user checkbox on the 3rd radius and create a hreap group then associate the 3rd one? i dont want the 3rd radius to be able for the gloabl list to take this as normal globla radius. any commnets?

Visio - bug - The server failed to process the request

Hi
When uploading a visio diagram into one of our sharepoint document libraries we then get a 'The Server failed to process the Request' error when we then try and view the document in the Web Browser. Does anyone know how to fix this?
Thanks

I understand that this is an old thread. The following might be useful to other readers engaging this issue in the future.
I experienced the same error message when provisioning a new instance of the Visio Graphics Service application for a new farm. I first tested the approach presented by sjb500 and found that this approach did resolve the problem. I then
explored using a more limited permission approach. Over the course of several attempts, I eventually found that I only need map the application pool identity to the SPDataAccess role to resolve the problem:

ForbiddenError: The server failed to authenticate the request. Verify that the certificate is valid and is associated with this subscription.

Im trying to connect to my azure subscription via powershell on my machine but keep getting the following error when i run a command:
ForbiddenError: The server failed to authenticate the request. Verify that the certificate is valid and is associated with this subscription.
The steps i have taken so far are:
1. get settings file
Get-AzurePublishSettingsFile
2. Import settings file
Import-AzurePublishSettingsFile -PublishSettingsFile "C:\Users\me\Downloads\credentials.publishsettings"
3. I then run Get-Azuresubscription with the following output:

OK. That won't work in Azure Automation though, as mentioned above. OrgID (recommended) or cert-based auth will need to be used. PublishSettings file won't work.
Correct, but the original question was:

I wanted to test automation script's core functionality without having to wait for the very very long time taken for an automation runbook

The Server failed to retrieve the requested data

I used to be able to open this site with firefox. I haven't been able to open it for 2 days. It does open in internet explorer.

This appears to be an error message which has it roots in MS DTC, Microsoft Distributed Transaction Coordinator.
This indicates that you somewhere manage to get a distributed transaction. This could be because of two things:
1) There are triggers on the tables that accesses linked server.
2) Your client code dabbles with some transaction class, like TransactionScope or similar.

Radius server 00.00.00.00 deactivated in global list

Hi
we unable to authenticate the users connecting to WLC over EAP-FAST from the ACS 5.1.
AD is integrated with the acs....
The error msg coming in wlc is :Radius server deactivated in global list
Radius server failed to respond to request(ID:xx) for client xx:xx;xx:xx:xx:xx:xx
I find that problem with time skew error happen between the AD and ACS. But after i configured ntp server in acs the problem
still exist.
I removed the controller from the acs and added back, same thing done in controller(reconfigured aaa settings).
But the problem not resolved
Thanks

After working with TAC, I resolved this issue recently. Increasing the timeout value did not help. On the WLC, try:
config radius aggressive-failover disable
As per http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080665d18.shtml :
If the aggressive failover feature is enabled in WLC, the WLC is too aggressive to mark the AAA server as not responding. But, this should not be done because the AAA server is possibly not responsive only to that particular client, if you do silent discard. It can be a response to other valid clients with valid certificates. But, the WLC can still mark the AAA server as not responding and not functional.
In order to overcome this, disable the aggressive failover feature. Issue the config radius aggressive-failover disable command from the controller GUI in order to perform this. If this is disabled, then the controller only fails over to the next AAA server if there are three consecutive clients that fail to receive a response from the RADIUS server.

WLC not integrating with Radius Server

Hello world,
I have the following situation:
One WLC 2000 Series (software version 7.0.230.0) with multiple SSID`s, one is with 802.1x integrated with a Radius Server.
Everything worked fine until fiew days ago, when users were unable to logon via they`re certificates on Windows XP.
The infrastracture didn`t suffer modifications.
What i have checked: Radius certification isn`t expired, client certification isn`t expired, the password between controller and Radius is correct.
There are no ACL`s between the WLC and the remote Server. I can ping the devices, other SSIDs on the same controller (wpa/psk) are working correct.
The AP`s are 1242.
I have tried deleting the SSID, configure it back. The OS on Windows Server is 2003 Standard. The AP`s are configured H-Reap.
I have increased the Server Timeout from Radius Authentication Servers from 2 to 30 sec.
The message logs recived on WLC Trap Logs:
RADIUS server X.X.X.X:1812 failed to respond to request (ID 161) for client xx.xx.xx.xx.xx.xx/ user 'unknown'

Can anyone help why i cannot log the users via 802.1x ?

Okay that is good..... this is what I would do next. I would create a test ssid that uses PEAP MSchapv2 and create a new policy in IAS that is basic. Allow 802.1x wireless and user group only and see if you can reconfigure one of the XP machines for PEAP. Can you also post a screen shot of your polices (connection and network) so we can review it.

WLC "radius server overwrite interface" setting

Hello
I'm looking at using "radius server overwrite interface" on a WLAN as a replacement for Called-Station-ID for Radius to match on SSID.
When I enable "radius server overwrite interface" on a WLAN and join a client to the SSID I can see (via packet capture) that the WLC is correctly sourcing the Radius packets with the WLAN's "dynamic" interface IP Address. The problem is that the Radius server doesn't repond to these requests. Radius is configured with rules to match the new IP address but I see nothing (pass or fail) in the logs.
Interestingly, the packet captures shows the correct NAS IP address (the WLAN interface IP Address) but always shows the WLC hostname as NAS-ID (regardless of NAS-ID settings on the WLAN or WLAN interface)
I've tried WLC software 7.4.110.0, 7.4.121.0 and 7.6.100.0 with the same results but Radius never responds. Radius is Cisco ACS 5.5.0.46. Any ideas as to why this is happening?
Thanks
Andy

Hi Scott
installed ACS 5.4 0.46.6 and I still have the same problem - ACS doesn't respond to request from WLC when "radius server overwrite interface" is enabled on WLAN and nothing appears in the logs. With "radius server overwrite interface" disabled on the WLAN, authentication is a success and I can see this in the logs.
I had a look a the packet captures I took earlier and the attributes in the Access-Request look ok - the only attribute I wasn't sure about was Message-Authenticator. Found this ietf document http://www.ietf.org/rfc/rfc2869.txt which mentions "silent discards" of Radius packets with non existent or incorrect Message-Authenticator attributes. I'm not sure if this is what I'm seeing on ACS when it receives the "radius server overwrite interface" Access-Request packets. ACS is under contract so I will contact TAC about this.
Mt production ACS cluster was upgraded from latest version of 5.3 to 5.5 with no loss of historic logs (logging after upgrade worked fine also). The upgrade did take a while with the log-collector. When it had completed I checked the Data Upgrade Status under Monitoring configuration and it showed that the upgrade was successful.
Thanks for your help with this.
Cheers
Andy

Tabish-
The pre-auth ACL that you have on your port is used for what's called a "Low-Impact" mode type of setup. With Low-Impact mode you are allowing services defined in the pre-auth ACL until the user/devices is authenticated. Once authenticated the pre-auth ACL gets replaced with the dACL/authorization policy that you have defined in the authorization profile. As a result, it is not possible to use "fail-open" configuration with low-impact as there is nothing to replace that pre-auth ACL since your NAD device(s) are unavailable.
If you want to use the "fail-open" features you will have to use the "High Securty/Closed Mode." In that mode you cannot utilize the pre-auth ACL and essentially only EPoL traffic is allowed on port until authenticated.

Detect up/down radius server

Hello,
I was wondering how does a switch proceed to detect when one or several radius server is down.
If I leave only one radius server in a C3560-24PS (running with the lastest software version) and shut all services associated with my ACS4.2 through the web interface, I receive the following error logs:
13:55:31:%RADIUS-4-RADIUS_DEAD: RADIUS server x.x.x.x:1645,1646 is not responding.
13:55:31:%RADIUS-4-RADIUS_ALIVE: RADIUS server x.x.x.x:1645,1646 is being marked alive.
Anyone can explain me why a such ouput?
Thank you for your help!
David

Hi David,
Following are the comments for the above messages
%RADIUS-4-RADIUS_DEAD -- A RADIUS server has not responded to repeated requests
For checking purpose check to see if the RADIUS server is still active.
%RADIUS-4-RADIUS_ALIVE -- A RADIUS server that previously was not responding has responded
to a new request
Hope to Help !!

I have a very similar situation here. Took me a while to figure out why existing user certificates are OK but no new users can enroll. I checked all certificates for expiry. No go. It was not the expiry ("Valid to") time, but rather the "Valid From" time that is messed up.
This is what happens: The rollover gets created and replaces the original one (which remains in memory, no flash) But the new one is valid from the expiry of the old one - in my case TOMORROW and after a power-outage the day before yesterday (the most definitive way to get a reboot!) I only have the new NOT YET VALID certificate.
OK, I can wait until tomorrow and see if it works. But the design is far from intelligent. The industry standard is that when you renew a certificate, the validity of the new one is immediate - even if it means it runs for a few days longer than the designated lifetime.
So much for the overlap period of 30 days (as you can see from your own post) if the old certificate goes away after a reboot and the new one is not yet valid! (The CA certificate expiration timer gets reset to some Unix time-zero ( 01:00:00 CEST Jan 1 1970) which I take to mean "not valid yet".)
I only have a few days of trouble - and just one to go after finally working it out, but it could have been up to 30 days if I for any reason had rebooted after the roll-over certificate got created.

Cisco ISE with both internal and External RADIUS Server

Hi
I have ISE 1.2 , I configured it as management monitor and PSN and it work fine
I would like to know if I can integrate an external radius server and work with both internal and External RADIUS Server simultanously
So some computer (groupe_A in active directory ) will continu to made radius authentication on the ISE internal radius and other computer (groupe_B in active directory) will made radius authentication on an external radius server
I will like to know if it is possible to configure it and how I can do it ?
Thanks in advance for your help
Regards
Blaise

Cisco ISE can function both as a RADIUS server and as a RADIUS proxy server. When it acts as a proxy server, Cisco ISE receives authentication and accounting requests from the network access server (NAS) and forwards them to the external RADIUS server. Cisco ISE accepts the results of the requests and returns them to the NAS.
Cisco ISE can simultaneously act as a proxy server to multiple external RADIUS servers. You can use the external RADIUS servers that you configure here in RADIUS server sequences. The External RADIUS Server page lists all the external RADIUS servers that you have defined in Cisco ISE. You can use the filter option to search for specific RADIUS servers based on the name or description, or both. In both simple and rule-based authentication policies, you can use the RADIUS server sequences to proxy the requests to a RADIUS server.
The RADIUS server sequence strips the domain name from the RADIUS-Username attribute for RADIUS authentications. This domain stripping is not applicable for EAP authentications, which use the EAP-Identity attribute. The RADIUS proxy server obtains the username from the RADIUS-Username attribute and strips it from the character that you specify when you configure the RADIUS server sequence. For EAP authentications, the RADIUS proxy server obtains the username from the EAP-Identity attribute. EAP authentications that use the RADIUS server sequence will succeed only if the EAP-Identity and RADIUS-Username values are the same.
