AAA/Identity/Nac :: 1841 Giving Error In Authentication

May 15, 2013

I have an 1841 that was working fine - I could SSH to it with my Radius login and console into it with local credentials ("Fred").I added another use ("Mike") with priv 15 so the end user could log in locally via console if needed.After that, we can both log in via console, but when we try to enter privileged mode we get "% Error in Authentication", before even entering the   password.I can still log in via Radius SSH with no problems and access privilege mode via SSH.What am I missing so we can have two different users be able to log in locally with different credentials and access privileged mode, and keep my ssh radius working?

Cisco AAA / Identity / Nac :: 1310 Bridges - FreeRadius Authentication Error

Mar 2, 2011

I have two 1310 bridges. one configured as root and the other as non-root. Authentication Settings: Open with EAP and Network EAP with no addition. Set up: when non-root bridge tries to associate with root bridge, root bridge checks with radius server if it's ok to associate with the non-root bridge.
I can see communication with the radius server (I'm using FreeRadius) and the radius server even sends a SUCCESS back to the root bridge. However I'm seeing this error on the non-root bridge: DOT1X_SHIM-3-PLUMB_KEY_ERR: Unable to plumb keys - Eap key struct is NULL and the bridges do not authenticate.

Cisco AAA/Identity/Nac :: 5508 - NGS Guest Server Authentication Error

Apr 29, 2011

I installed NGS 2.0.2 for wireless guest user management and authentication. I implement webauth via webauth page on wlc deployed.One Branch with a WLC5508 version 7.0 wireless anchor controller is working on the NGS.But now I integrate next branch with WLC4402 version 6.0.188 and the authentication of users at the new branch gets an error, wrong user/password.
I double checked configuration and user/password but I can't find any configuration error. Also stopping and starting of radius service and reboot of NGS still does not work. I tried to debug the radius via web interface and watched for the loggfile and there is still a reject.I also tried the freeradius command radiusd -X but I got an error when starting the radiusd -X.
1.) How can I figure out, if I will get the correct password from my WLC ? Are there any debug options to see more ? e.g. some cli commands, radiustest utilities or how to get the received password from the chap challenge of the debug ?
2.) I have appended a part from my radius loggfile. How can I find the detailed error in the radius log file? Is it correct that the password in the debug file is empty ? raiuds logg line "[radius-user-auth] expand: %{User-Password} -> "

Internet Is Giving Limited Connection Error

Apr 22, 2013

I am currently on Time Warner Cable 10 mbps packge, and am using their wireless DOCIS3 modem/router. It is connected in my bedroom to the main computer. That computer stays connected. However, throughout the rest of the house (we have a two story townhome) it will drop completely or give limited connection...constantly. Sometimes I can have my laptop next to me and it will go out or give limited connection. The connection speed never drops, it just goes completely to no connection. Not for sure what is going on, if its on my end or time warner. Has been doing this for quite some time, the cable company comes out and changes the modem, but that's it, couple days later, goes back to doing it again.

Cisco :: After Connecting VPN Giving Connection Timed Out Error?

Jul 24, 2011

I had been working on our client servers through Cisco VPN using internet datacard. But from past 3 weeks after logging into Cisco VPN using my username/password, when I try to connect to any of the servers, it is giving connection timed out error.

Whereas, my team members across other locations are able to connect to the servers using my VPN username/password.

I thought there might be some issue with my laptop or internet datacard. I got my laptop formatted, even tried out with fresh new laptops & new internet datacards, but the issue remains same.

I have tried using vpn_5.0.06.0160-k9 & vpnclient- to connect but issue did not get resolved.

Cisco Switching/Routing :: Nexus 5596 Giving Error In Connection

Aug 28, 2012

I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX i'm not sure...
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus,  going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

Cisco VPN :: 3825 - VPN Client Is Giving Error And Unable To Create Certificate Enrollment Request

Feb 21, 2011

We find ourselves in a difficult situation with the Cisco VPN Client version where it keeps giving us an

"Error 42: Unable to create certificate enrollment request"

When we attempt to use the Online enrollment method to create and enroll a new certificate. There is no additional information in the VPN client logs where we have set 3-High for all logs. In addition, Wire shark does not show any packets sent from the machine running the client to the Cisco 3825 router which runs the Cisco CA.
To create and enroll a certificate we do the following:

1. Click on the Enroll button to show the Certificate Enrollment dialog
2. Select  Online
3. Select <New> for Certificate Authority
4. Enter as CA URL (note, is the IP of the Cisco 3825)
5. Click Next to display the dialog where we can enter certificate details
6. Enter details in all fields except IP Address and Domain
7. Click Enroll which shows a dialog with the Error 42 ... message in it.
If we attempt to create a request by using the File method, all works fine, that is, the client creates a file with the enrollment request. The fact that the client does not send any messages to the Cisco CA leads us to believe that we have a problem on the client machine. However, the client does not write any information in the logs, so it is a bit hard to fix the problem. I can provide additional configuration information if required for both the client and the Cisco CA. Note that we have not modified any client configuration. Basically, we installed the client on a Windows 7 64bit machine and attempted the steps listed above.

Cisco AAA/Identity/Nac :: ACS V5.3 Identity Selection For Authentication?

Jan 16, 2012

I configured before ACS v4.2 to authenticate network devices using internal users at first, and if the user is not found use AD list users.  But with v5.3 I have some problems doing this, on identity policies I use rule based result selection option, I configured 2 polices for Identity source, one for Internal Users and other policy for AD user, but it only works with the first policy, internal users or AD, but works only for the first policy identity.  how to do that, if the user is not found on first policy, continue to the next policy.

Cisco AAA/Identity/Nac :: ACS 5.2 Error - 22056 Subject Not Found In Applicable Identity

Oct 6, 2012

I have two ACS v 5.2 (primary and secundary) and some users are in the internal stor and the others are in the AD.The local site topology is like this:
PC - AP - WLC - ACS - AD
Authentication method is PEAP(EAP-MSCHAPv2) and all user have the certificate company installed. The OS in the client users is Windows 7.Users was working fine but some users reports intranet disconnections. I see in the ACS log  many "22056 Subject not found in the applicable identity store(s)." and "24415 User authentication against Active Directory failed since user's account is locked out" alarms.I believed it was because user wasn´t in the AD data base, but some times the same user is authenticated successfull and other i see the "22056...." or "24415...." alarms.
I switched the role for ACS primary to works as secundary and we see the same alarms.

The security settings are WPA/WPA2. When I try to connect, the phone is able to see my Wi-Fi network, and it asks for my password, which I enter. It keeps trying to connect, but then it says an "authentication error occurred." I have checked and triple-checked the password, and it is correct. I have also checked and triple-checked the MAC address, and it is correct. I have rebooted the router and the phone several times each.
