Cisco AAA/Identity/Nac :: 3560 / TACACS (Command Authorization Failed)
Jan 3, 2012
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 tried to configure TACACS+ authentication / authorization for NCS via ACS 4.2. For that I followed the configuration guide:
1. Configured the service for NCS with HTTP (see attachment)
2. Added the tasks to the user (see attachment)
When I try to login on the NCS it fails, in the logs on the NCS I see the following lines:
09/14/11 16:53:03.333 TRACE [system] [http-443-7] [TACACS+ AAAModule] Creating authorization socket - To Server: 192.168.49.14 - For User: netadmin

I can get it to authenticate. But I've read some posts on ACS 4.2 and authorization, but I don't find anything similar.I want to control down to what commands the authenticated user can run. I want the defintion to come from the ACS server, or at least control it from the ACS server. I want to minimize the changes on the JunOS side,but if it can't be easily done, I'll change the JunOS side.

ACS 5.3 configured with two rules, 1 rule for standard level 15 access for the Network Engineers and a 2nd rule to allow some limited access to switches: The limited access account has enough command set access to change the vlan on a switchport, so Configure Terminal, Interface FAx/x and switchport access vlan x.
Switch configuration:
aaa authentication login default group tacacs+ local
aaa authentication enable default group tacacs+ enable
aaa authorization console
aaa authorization config-commands
aaa authorization exec default group tacacs+ local
aaa authorization commands 0 default group tacacs+ local
aaa authorization commands 1 default group tacacs+ local
aaa authorization commands 15 default group tacacs+ local
aaa session-id common
Everything works well and the limited access users can only perform the commands i've setup.
Problem:The problem i've encountered is when one of the network engineers makes a change that would stop the device from being able to see the ACS server it stops allowing any commands to be typed in the router/switch. Additionally if you then connect to the device and login with the local username and password the device then waits for it to hit the TACACS server timeout for every command you enter. This is obviously very slow and painful for the engineer.
Question:Is there a way to set this up so the engineer logging in with full Level 15 access doesn't have to have each command authorized by the ACS server but still allow the limited access accounts to be able to make interface changes?

Noticed tacacs authorization logs when you change password for a user ?? in authorization logs I can see the new password but same I can not see in accounting logs ? is it a normal behaviour ?? or do we need to do something to hide the password in authorization logs ?
For example if i type command username xyz priv 15 secret cisco 123
I see this command in accounting logs as uername xyz oriv 15 secret *** where as in tacacs authorization logs it shows username xyz priv 15 secret cisco 123

I am having an issue with authorization on the Nexus 5548. Note: The tacacs configuration has and still works correctly with all non-Nexus gear.
Authentication succeeds, and initiatial authorization passes. However, all sh and config commands fail, though AAA Autho Config-Commands .... and Commands Default Group <Grp Name), are configured.
ACS generates the following error: 13025 Command failed to match a Permit rule. The Selected Command Set is DenyAllCommands. I created an AllowAll, but am unclear how to associate this with Access Policy.

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.

I have a pair of ASA 5520 firewalls running in active/standby mode on 8.3.2.34 code. My configuration performs authentication/authorization into ACS 5.1, however command authorization is failing when I try to execute a command on the standby from the active unit...
failover exec standby dir disk0:/
Fallback authorization. Username 'adminuser' not in LOCAL database Command authorization failed
I don't even see the authentication attempt going into ACS.

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)

Using ISE 1.1.1 and Switch 3650 12.2(55)SE6. I have a client (computer) that should be authenticated with MAB and then the switch port should be asigned a DACL and VLAN 90. I do get "Authorization succeeded" but directly after it fails and I can't figure out why. ISE only shows the successful authentication under "Live Authentications".
As you can se from the log below 802.1x fails, as it should, and then MAB succeed, asigns the VLAN and then fails:
0002SWC002(config)#int fa0/13
0002SWC002(config-if)#shut
0002SWC002(config-if)#

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've been configured my device 6506-9 with TACACS+ server authentication: [code]
but when I tried to access the device only uses authentication local but not uses TACACs (with username/password defined) it can be an error in configuration? in the other devices of network this works properly, only it's wrong in Cat6506-E

I have two WLC-5508 for 50 AP's deployed. One is primary controller & other is secondary.Recently noticed an unknown "authorization failed, no sufficient privileges for user" message poping up while making configuration changes in WLC. Specificly when trying to create an new SSID. WLC Authentication is local. This message poped up earlier once or twice but it didnt prevent from making changes that time.

I'm doing some tesing in SFE2000P linksys switch about the TACACS authentication. I have configured the switch accodringly to point my ACS server with key string. Now, I'm able to login into the switch with TACACS account in HTTP/HTTPS only and but, not with the TELNET access.
Still Switch is authenticating with the local user account only, when in TELNET access method.

I'm trying to set a VPN connection to a router using group authorization with the ACS 5.2 but cannot make it work. I configured everything based on the procedure used for ACS 4.2. I created a user that corresponds to the group name, used the password cisco and used all the requiered Cisco AV pairs in an authorization profile. (Based on document: [URL]
While testing with ACS 4.2 this works fine, I can see that the ACS returns the group attibutes correctly (here is a debug output)

Have a conceptual question bout CLI command authorization. We have ASC 5.2 up and running, providing AAA services for network devices. Now I need to make profiles for users in certain group to restrict dem CLI "rights" to show, clear counters and show running-config commands. I need to accomplish dis task.I should clrete separate privillege levele profile (let it be 2), specify commands at this level, assign Group this Authorization Prifile and make some additional changes in my devices.

I am in the process of setting up an ACS evaluation that will authenticate against a Windows 2003 AD. I am currently testing this with AAA TACACS+ but will evenutally setup 802.1x authentication. My problem however seems to be between the ACS and AD.
I have the AD External Identity store configured and successfully tested for connectivity. I created a shell profile and a command set and also created an access ploicy for Device Admin. I added the AAA commands to my test switch and do get prompted for username and password. This is where my issue starts. Regardless of what username and passwword I enter, I always fail authentication. At least that is what is in the reports and I have 0 hits on my Access and Authorization policy rule. I am using as basic as a config as I can get with simply using a contains from one of the groups I am in for the policy rule. I had a non-AD admin account to start with thinking maybe a rights issue with the AD account but have moved to an AD admin account with no change in the results. I saw a post somewhere that the time stamps on the AD server and the ACS had to almost be perfect and recommended that NTP for ACS be the AD server as that could cause issues and I have done that as well with no change. I am wondering if there is something specific I needed to configure or something I missed between the ACS and the AD? Is there a way I can display what is passed back and forth between the ACS, or the switch, and AD to verify content? I put a call into my local SE and he is as puzzled as I am.

I have IAS set up on my organization's AD domain controller. Multiple policies set up for various authorization scenarios, authenticating based on Windows user groups and client IP, authorizing by passing "shell:priv-lvl=#" where #=desired privilege level. On my IOS devices I have:[code]
This identical configuration operates correctly on a Cisco 3825 and a Catalyst 4506. On the 24 port Cat 3560G PoE running 12.2SE (do not recall exact IOS version, but I know it is in that release train) that I am currently working on, every attempt to login via ssh passes authentication but fails authorization, displaying %Authorization Failed on the terminal and a message stating that "No appropriate privilege level found for user" in the debug statement from RADIUS.I have verified correct server addresses, correct source-interfaces, and that configs between the three devices match exactly with regards to aaa.

In the process of migrating from ACS 4.1 to ACS 5.3. Authentication works fine, but having issues with authorization on the Juniper WXC-3400 devices. In ACS 4.1 we were passing TACACS+Shell (exec) Custom attributes Privilege level=15, which allowed a user to login with read/write privileges. In ACS 5.3 tried setting the Shell Profiles common task to 15 for both Default and Maximum (one at a time, and together), as well as setting the Custom Attributes for priv-lvl=15 (with and without Common Tasks set).
A capture shows Auth Status: 0x11 (ERROR).

I am trying to move my ISDN dialup branches authentication/authorization from old ACS 4.1 to ISE appliance. Before it was through ACS 4.2 with TACACS protocol but now since we are moving to ISE we are moving them to ISE with radius.
Problem is that isdn client gets authenticated and authorized but calls get dropped and they dont able to communicate with HO. IP address is assigned by Head End router to all remote isdn dialing branches..
I have used default "PermitAccess" in authorization policy and authentication policy is also default. I dont understand where I am going wrong as authentication and authorization is sucessful.
aaa authentication ppp default group radius local
aaa authentication network default group radius
aaa accounting network default start-stop group radius
radius-server host 12.18.22.41

1 ) : Is it possible to do authentication with one ACS server while authorization with another ACS? Use case is if the user authenticated to one ACS server and then switch loses the connectivity to this ACS. Now command authorization requests will go to another ACS server since switch is not able to communicate to the 1st ACS.
2): How can the local database sync be acheived in distributed ACS deployments?
3): Are the accounting records are sync between different ACS? In other words can accounting be centeralised with ACS4.2

I have a Cisco ASA (8.2) setup with remote access for my users using Cisco VPN client. The authentication is passed off to my ACS 5.3 which then checks with AD. What I've done so far is create Access Policy rule where I define specifically the Location and NDG where the ASA is and then a DenyAllCommands command set. This should pass authentications just fine but this also gives those users the ability to remote connect directly into the ASA and login successfully. Even though there is a Deny Commands there I still would prefer they get Access Denied as a message. If I do a Deny Access on the ShellProfile then this stops the login authentication altogether.
