I have a problem trying to export logs to the Cisco ACS View from my ACS 4.2In the document [URL] Cisco states that one of the mandatory attributes for export to work is "Network Access Profile Name" under TACACS+ Accounting (under ACS 4.2 System configuration -> Logging settings). Well, I don't have this mandatory attribute listed in ACS under TACACS+ accounting log configuration. I tried to ignore this attribute, but then ACS View complains about null value for the attribute mentioned above.Is this some bug in ACS View or ACS or maybe I simply missing something?
View 1 Replies View RelatedI have two Nexus 5520 running 5.0(3)N1(1c).
I have both boxes heading off to ACS for TACACS lo gin authentication and for command authorization. When I first set things up everything works fine. I have a shell profile configured in ACS with Cisco-av-pair*shell:roles="network-admin" to set the network-admin role. I even have command sets configured to deny the use of configure terminal as I am using switch configuration profiles. Everything runs fine. User lo gins are authenticated by ACS and users have the correct command set applied to them.
The problem comes when I make a change to a shell profile in ACS. Even something as simple as changing the name of a shell profile causes the 5520's to crash as soon as I try to log on. If I unplug the management link so that the TACACS server is unavailable I can log on fine with the local admin user.
The NEXUS console reports this error. (amongst many others)

View 5 Replies View RelatedSo far i managed my switches with TACACS+, however now i've to deploy 802.1X, requiring RADIUS only. For what i know, ACS (i'm using 4.2) allows to define a device using only TACACS or RADIUS, but not both. Do i am right? Or there is a way to define an AAA client to communicate with the same ACS using both the protocols?
Supposing i am right, i was then considering the following options: - configure all of the switches to use radius for any service (authentication, authorization etc ec) This simplifies the task, but i lose the TACACS+ services for the switches. Is this a big loss?
- configure the L3 switches to use a second Loopback, just for RADIUS services. This would allow to still use the TACACS+ but would require a new network just for the RADIUS service; furthermore L2 switches doesn't support two IP addresses and would require anyway a migration to RADIUS.
A considerable administrative overhead, in other words. I'm not willing to deploy a second RADIUS (ACS, Windows, whatever), in this moment.
The key point is this: reading around i see Cisco documentation recommending always to use TACACS+ for management, but in this situation is not possibile. In general, every time the device has a role of network admission (switch or access-point) RADIUS seems to be the protocol of choice. Moving to RADIUS would have some major drawback or only a change in the communication protocol? (I know the difference between TACACS+ and RADIUS: tcp vs udp, encryption of the whole packet vs encryption of only the password).
IS there a way to stop the Radius/Tacacs service in ACS 5.2 from the GUI ?
View 6 Replies View RelatedOur ACS 5.2 is authenticating ASA VPN users with Radius. I would like to use the ACS to authenticate ASA administrator logins with Tacacs. When I modify the ASA Network Device by checking the Tacacs box in addition to the Radius box, ASA VPN authentication stops. Running original 5.2 without any patches on ESX. platform. I thought 5.2 supports radius and tacacs on the same device?
On subsequent tests found that just opening the ASA Network Device and closing the window will also stop the ASA RADIUS from working. Logs don't show any attempt by the ASA to connect and I'm sure that's wrong. To fix it, I reselect all ACS policy items and save the same settings. Sounds like a bug?

View 2 Replies View Relatedis there a way to assigen a QoS service policy via Radius to an Caltalyst 4500/3750 Switchport?
in detail, we would like to assign this policy
policy-map SET_EF class class-default set dscp ef
to an interface. All traffic should be marked with a defined DSCP value.
This works find when doing it statically with
interface FastEthernet2/1 service-policy input SET_EF
but we would need to assign such a policy via Radius during the 802.1x Authentication. different users should get differnt policies. We use Cisco ACS 5.2 as Radius Server and there actually is a field for that in the Authorization Profile Common Tasks Configuration. in detail, this uses the cisco-av-pair "sub-policy-In=<policy name>" attribute to assign a service policy to an NAS.
we found also two other attributes "sub-qos-policy-in" and "ip:sub-qos-polcy-in" for that. CCO says that "ip:sub-qos-polcy-in" works with Catalyst 65k [URL]
unfortunately this seems to not work on Catalyst 45k and 37k.
In the ACS Logs we can see that these attributes are attached to the Radius Reply, but unfortunately they are ignored by the switch.
it is interesing that when entering "show aaa attributes" on the Catalyst 45k, these attributes are displayd - so for my understanding the switch should understand these attibutes (?)

I have been experimenting with acs 4.2 and a cisco asa 5510. I have managed to authenticate the ASA users with my tacacs server. The user "test" is authenticated with the tacacs server, and can log in. But the enable password is wrong, because i dont know where to place it in the tacacs server.

View 1 Replies View RelatedI am in the process of setting up ACS 5.2 for a network and have run into an issue when attempting to apply the following aaa commands to a network device:
aaa authorization exec default group tacacs+ local if-authenticated
aaa authorization commands 1 default group tacacs+ if-authenticated
aaa authorization commands 15 default group tacacs+ local if-authenticated
Once the commands have been applied to the device configuration I get "command authorization failed" when attempting to do anything. Taking a quick look at the TACACS Authorization reports I see a failure reason of "13025 Command failed to match a Permit rule" and under the Selected Command Set "Deny All Commands" is listed. After doing a bit of searching, I noticed some articles online that indicate I should be able to specify the appropriate command set to the authorization profile under the Default Device Admin policy. However, when I open up a Device Administration Authorization Policy, nowhere in the window does it display command sets that I can select from.
I have a Cisco ASA (8.2) with several group-policies setup. By default, I can hit the SSL page, and have a selection of available group-policies for a user to login to. I want to have different ACLs for each group, to go along with the subnet that each particular group hands out. Right now, as long as a user is authenticated through AAA, they can log in to any group they select, and therefore, have more permissions than another group.
I know how to hide the list, but I need to be able to assign a specific group to a user based on an attribute in ACS.
I've setup ACS to use the "CVPN3000/ASA/PIX7.x-Tunnel-Group-Lock" Atttribute, to which I match the group-policy name in the ASA, to the attribute on the user account in ACS.This doesn't seem to work, and it just throws the user into DfltGrpPlcy, which doesn't give the user anything. So it's either wide-open, or it's broken.
I'm using RADIUS authentication and not TACACS, so it should retrieve the attributes, and according to the ACS, it grabs the attribute during the authentication process.

View 1 Replies View RelatedI 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.
View 2 Replies View RelatedI think i've got everything set up to authenticate against AD for Tacacs+ device logins. When i check the logs, i see:"24408 User authentication against Active Directory failed since user has entered the wrong password". This leads me to believe that it is checking AD correctly, however if i enter the password correctly for the same AD user, there is no log at all...no pass, no fail.
If i look at the Tacacs debugs on the switch, i see the following:May 25 10:55:07.927 CDT: TAC+: ver=192 id=874699084 received AUTHEN status = ERRORMay 25 10:55:09.932 CDT: TAC+: send abort reason=Unknown
Obviously the switch is communicating to ACS, and ACS is passing info back to the switch. ACS also appears to be communicating effectively with AD since it knows when i put in an incorrect password for the specific user.

Switch configuration:

aaa authorization commands 1 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?
