Cisco AAA/Identity/Nac :: Authentication With One ACS 4.2 Server While Authorization With Another
Apr 5, 2011
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 set up LDAP store pointing to a Windows domain and am testing authenticating users via an ASA. In my LDAP config, its set for "Groups Objects refer to subjects" and I selected usernames in the drop down. I also added a a Global Group to the Directory groups tab in the LDAP store that I created.
Under my Access Polices, I created a rule that meets two condititons - coming from the ASA, and then I was able to select the group from the drop down box for my ldap domain. As a condition, it shows up as DomainName:External Groups. I set the permission to Permit Access.
Originally, I was failing authentication and I was receiving Subject Not Found in Store. I adjusted the Identity Sequence and now I receive a the following error:
15039: Selected Authorization Profile is Deny Access. So it must not be associating my account with the group with the Permit Access and using the Default Permissions.So it does match the correct Access Service, and Identity Store.
We got 2 Cisco ACS 5.2.0.26.10.Primary server as authentication server and log collector.Secondary server as authentication server. Replication is configured. url..."There are some exceptions to this usual setup, which you can handle as described below: If the ACS 5.3 primary server also functions as a log collector in your 5.3 deployment, you should promote any one of the secondary servers as primary server in the deployment. See Promoting a Secondary Server to Primary "
This exception matches with my case. I have to promote my secondary server as primary.I would have :Secondary server as authentication server and log collector.Primary server as authentication server. I think I have to deregister secondary from primary server..According to the guide, I have to upgrade the log collector server. "Step 1: Choose any secondary server to become a log collector:" I dont have another secondary server..
Does Cisco Secure ACS 5.3 support LDAP authentication with Apple Mac OS X server? One of our clients require an access control system. The major portion of the network consists of Apple Mac OS X 10.7 (Lion) Server and clients. They were using MAC-address based authentication along with LDAP through Cisco Wireless LAN Controller. But now the number of users has exceeded the maximum number of MAC addresses supported by WLC (2048). Hence we suggested ACS appliance to overcome the limit. My doubt is whether ACS 5.3 appliance can communicate with the Mac server and perform LDAP authentication.
I have a customer who used to own a 3750 with a older version of IOS. The switch he had used a three year old version of IOS which allowed him to browse to the switch IP and manage it via HTTP without entering a password at all. Now that he has a replacement switch with a new ver of IOS (since the previous switch died). We slapped the config on from the old switch but no matter what we do (understanding that new http aaa authentication commands were added) we cant get this thing to let him in without prompting him for a password. I understand this was an insecure config to begin with so I shouldn't be advocating using it in the first place, but this is what the customer wants.Basically what I'm trying to figure out is are we banging our heads into the wall for nothing as the "ip http server" will not allow an authentication method of "none" anyway? None of the offical documentation I have read for the http aaa authentication cmds shows this as an example nor have I found any blog posts on how to do it ether. Perhaps Cisco removed this by design.
Here is the config:
aaa new model aaa authentication login default local aaa authentication enable default none aaa authentication login none none ip http server ip http authentication aaa login-authentication none
I'm looking for Cisco ISE v1.1 to use the following licensing feature. url...Endpoint is dynamically profiled by Cisco ISE and assigned dynamically or statically to an endpoint identity group. Cisco ISE authorization rules do not use this endpoint identity group.
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 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} -> "
I would like to configure RADIUS authentication and authorization in ASA 8.2 (ADSM 6.2) by configuring Cisco anyconnect VPN client connection profile.So the end result would be user enters his username, password and a token in any connect client, then the RADIUS server validates this information and sends the user attributes to ASA upon successful authentication.I would be grateful if i can get the step by step procedure to achieve this:The below is what iam trying to do:
1) Create an AAA server group. 2) Add the AAA server to this group (here its RADIUS). 3) create an LDAP-cisco ASA group mapping (for authorization) 3) Add a group policy and create IP pool. (We can add two types of group policies, one is internal and external. Not sure which one to select here). 4) create a any connect vpn client connection profile. Here we specify the created server group name, IP pool and group policy.(While creating a connection profile, it asks us to select an interface. As of now i have only one interface which is "inside". Not sure what the interface "outside" means).
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 create a one profile on PIX/ASA Command Authorization Sets & MAP with Group & Ldap with My AD. but authentication is not done as per the set parameter on command authorization in ACS.i am using Cisco ASA 5505 & ACS 4.2.
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).
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 radius-server key *****
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
A short background. Our corporate SSID is being migrated from using PEAPv0 to EAP-TLS. This restricts access only to company notebooks. Additionally we have barcode scanners which are used to inventory assets. Those devices are not able to use EAP-TLS as they cannot be integrated in the domain and being unable to do certificate based authentication.
As a workaround we planned to use another SSID with access to the same network but using PEAPv0 as authentication method, basically the same SSID but with a different name. As this naturally allows anyone to access the corporate network with a valid username/password I now wanted to add another step into the authentication process - the MAC of the device. I know I can do the filtering at the WLAN controller, but as it has a limited database as well as the fact that it is cumbersome to maintain the MAC list on all the controllers I thought I can do it over our ACS system.
I am now trying to accomplish the following: The user gets authenticated via the internal user store, which is succesful. Now I want to authorize the user via the MAC address, which is stored in the internal host store of the ACS, if access is granted or not.
For this I created the following policy:
Service Selection Policy -- (Rule based result selection)
-- (NDG:Device Type in All Device Types:Wireless And RADIUS-IETF:Called-Station-ID contains <SSID>) | Result: PEAP access
-- Default | Result: DenyAccess
Service PEAP access Identity: Internal Users -- (Single result selection) Authorization -- (Rule based result selection) -- Internal Hosts:HostIdentityGroup in All Groups:Valid_MACs
When I then try to access the wireless network I won't get authenticated. The error I get, when I look into the logs is: 15039 Selected Authorization Profile is DenyAccess
Is it not possible to use one identity store as "attribute database" for the other identity store?
For ACS 5.4: In Network Access -> Authorization Profiles there is a Permit Access profile. If you try to edit it a message pop's up that says: "The profile you have selected is reserved and cannot be deleted or modified". What this profile contains in its rule base? If I wanted to create a similar profile what Common Tasks, or Radius Attributes would I need to use? The same would go for a Deny Access profile. I have looked at the Common Tasks and Radius Attributes for a new profile and it doesn't seem very intuitive.
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.
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.
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:
I am setting up Radius AAA for cat6K switch.For authentication its work and user can login to switch. But for the privilege level assignment, it does not work. After loging in, I always get privilege 1. I need your guide on how to configure on ACS 5.1, RADIUS Attribute.I follow the document to configure the cisco-av-pair for assign Privilege 15 and Privilege 5 , but it does not work.This attribute format was shown in document is to set Privilege 15, "shell:privlvl=15" it is correct way of configure it on ACS 5.1
I have an ASA 5520 8.2(5) with ACS 5.1, I made the configutation of Authentication and is working well, now how I can configure the authorization and get into the privileged level 15 mode directly.
I have defined Radius proxy on csg2 to external radius server, but pdp fails with Authorization failure message on GGSN and on Csg2 debut log I see “SAMI 3/3: Nov 23 15:11:43.937: RADIUS: Dropping the unsolicited RADIUS packet”
I am trying to solve this problem without success so far. I have fresh ACS 4.2.15 patch 5 ACS installation and I am tryng to deploy it to our environment. So I have configured one 2960S to be my test client and everything works fine. Problem is when I try to create fine grained policies using network device groups and shell authorization sets.
I have created shell authorization sets called ReadOnly and FullAccess. I have also created NDG called FloorSwitches and added my 2960. I have 2 user groups called FloorSwitchesReadOnly and FloorSwithcesFullAccess. Now, if I configure group FloorSwitchesFullAccess and assign Shell command authorization set per NDG and then log into the switch, all of my commands are refused as unauthorized.
One thing that I have noticed is that if I assign shell command authorization set to any device ( in user group settings ) it works fine. Or if I create association with DEFAULT NDG in user group it also works. So my conclusion is that ACS for some reason does not associate my switch with correct group but rather puts it to DEFAULT group for some reason.
