I am using ACS 5.2 and attempting to authorize users through TACACS to Nexus 5.1 code. I seem to have ACS setup correctly based on documentation I received through here. The problem is that the NX/OS doesnt seem to be operating as expected.
View 2 Repliesmy customer has FreeRadius, and I'm trying to get the server to assign a network admin role to a 5K running 5.0.3 code.This is based on the example given in this document: url...The server authenticates the user name, but will only put the user into the network operator role. This is confirmed by checking the output of show user-account and debug security user-db.The Radius test using the same credentials passes the authentication test. I'm sure the problem is that the N5K dosent understand the VSA format of the attribute, and that this is a simple syntax problem.

Is there any way to link the Role-based CLI views created in the AAA client to the user created in the ACS 5.2 server? I know that you could do that in ACS 4.2 by using the “cli-view-name” attribute.What I have in mind is to login with some user and that the ACS 5.2 server links this user with a view previously created in the AAA client:This is what I would like to achieve:view configured in the AAA client:parser view DiData secret 5 $1$jPNA$gr9o8gGNmWh9sk8Axbfx91 commands exec include copy running-config ftp commands exec include copy running-config commands exec include copy startup-config ftp commands exec include copy startup-config commands exec include copy commands exec include all show Login to the device using a user created on ACS 5.2 and linked to the above DiData view:

View 1 Replies View RelatedI've got two Nexus 7010's running HSRP north bound to a pair of ASA's, and BGP south bound to four 6509's. Is it possible to advertise default route to BGP neighbor (or prefer it via MED), only if the node is HSRP-active?
Essentially the goal is to create symmetry for inbound/outbound traffic. Only way I can think of so far is via an EEM script, so that when it sees HSRP go active via syslog, it would kick off an action to remove ASN prepend, or reduce MED, and the opposite if HSRP goes standby.
I have a Nexus 5500 which is the core of our network and we have access layer switches uplinked to it. I know by default the qos markings will be trusted.
1. On a trunk uplink from an access layer switch to the Nexus, I have "mls qos trust dscp". Will the DSCP marking be preserved when it reaches the Nexus?
2. How do I do prioritization of voice traffic on an uplink on Nexus based on DSCP EF?
I am configuring a new ACS 5.3 system. Part of the rules is that I want to match the users specific AD group membership, and match appropriatly to an identity group.What i'm trying to do is say that if the user is a member of the AD Group (G-CRP-SEC-ENG) then associate them with the Identity Group SEC-ENG. The under the access service, authorization portion, i assign shell profiles and command sets based on Identity Group.It seems that the ACS server will not match the AD Group for the user, and it will match the Default of teh Group Mapping portion of the policy every time.
I tried several configuration choices from : AD1:ExternalGroups contains any <string showing in AD>, AD1:memberOf <group>.Is there something special i need to do in the Group Mapping Policy to get it to match and active directory group and result in assigning the host to an Identity Group?
I have 2 types of network, DC & Office. I have 3 types of users NOC, Office & DC. Office network devices are in Office NDG, DC network devices are in DC NDG.

How can i achieve this?
View 6 Replies View RelatedWe use a combination of Cisco ACS and Cisco catalyst 3560 switches for network authentication and authorization. Clients (Windows XP) have a certificate installed which will grand access to the network and put them in the correct VLAN. So far, so good. Some users are testing with Windows 7 in the same set-up as above and run into strange behaviour. The problem is that after a random timer the machine gets de-authenticated and nothing besides a reboot works to get the computer authenticated again (from a Windows point of view). It looks like this only happens to users who are using a certificate to authenticate, Windows 7 MAC bypass users have no such problems. If it occurs, the following logging appears in ACS: [code] We are using ACS 4.2(0) Build 124 and 3560-48PS switches with IOS 12.2(55).
View 4 Replies View RelatedA 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?
How to implement certificate based 802.1x authentication network access using ACS5.3 & external identity store as AD.
View 13 Replies View RelatedI'm trying to configure ACS 5.2 to assign the VLAN to a user dynamically based on the AD group that the user belongs to. I've gone into:
Users and Identity Stores -> External Identity Stores -> Active Directory -> Directory Groups tab
and selected the group name from the AD. If I understand correctly, I should now see this group under:
Policy Elements -> Authorization and Permissions -> Network Access -> Authorization Profiles -> Common Tasks -> VLAN ID/Name
However, it does not. Am I missing something?
using ACS 4.2 and I can't find a way to bind an incoming NAS port to a specifc IP Pool:
When a user connects the request to auth comes from 2 possible NAS ports randomly (this cannot change). Depending on which NAS makes the requests determines the IP range required, so I need 2 IP Pools. There is no way to say 'if request comes from NAS1 give IP from Pool1 and if request comes from NAS2 give IP from Pool2'
I have gone around and around with NAFs and NARs, but cannot do this.I can create 2 ACS groups with the specific NAS and specific IP pool within, but then I cannot have a single username bound to both groups.
I moved the auth to an AD group in the hope that I could bind that single AD group to the 2 ACS groups; and so have a single username, but no joy.
I recently saw a Cisco demo of ISE with a customer and the Cisco SE was setting the port description to the logged in username (dot1x). I can't find any docs on doing this. I did find some old ACS docs that mention using an AV pair and sending aaa:suplicant-name in the result, but that isn't working. I'm trying this on a 3750. and using ISE.
View 3 Replies View RelatedI am deploying ISE with WLC 7.4. I have two SSID(s) running in my network 1. Corporate & 2. Services. I have a domain setup lets say "AD.com" with 4 groups 1. Corporate, 2. Services, 3. Employees, 4. Contractors.Here is an example of the scenario that I want:
AD.com Group : Corporate's User : 1. C_USER1
2. C_USER2
3. C_USER3
4. C_USER4
5. C_USER5

Now what I want to do is have 802.1x authentication on my Corporate SSID that will check in AD.com, ONLY AND in ONLY corporate group for authentication. That is only C_USER1 to C_USER5 are allowed to connect to it. Users from any other AD group shouldnt be authenticated on this SSID.The same for the services group & SSID.
I've been working on trying to get RADUIS authentication working for devices connecting to our corporate mobile APN. Out APN provider sends us Username & Password attributes which I can authenticate fine using ACS 5.2 but I'm having a problem using other attributes sent in the Access-Request. We have mobile SIM cards with an MSISDN value match with a physical device with an IMEI value. The SIM cards cannot be used in other devices, only their matched device. The provider passes us the MSISDN attribute under RADIUS-IETF 31 and the IMEI under a VSA of 3GPP-IMEI
What is the best way of being able to authenticate a user and match the MSISDN and IMEI associated to that user?
I'm trying to find out the options for authenticating remote users via IMEI and MISDN values via ACS 5.3/I'm unfamiliar with the Radius attribute options here and what kind of request/response we can utilise. Also previously I could define IP pools on ACS 4 but can't seem to do that now. Is there a way have ACS 5.3 to provide a DHCP server address for the connection ?
View 6 Replies View RelatedLooking to fine tune Cisco IPSec client RA-VPN authentication on our ASA-5510. Currently using NT Domain authentication. It's been working fine for quite a while but is too broad a brush. It authenticates anyone who is in the domain. We need to only authenticate folks who are in a specific AD remote access security group. I'm testing LDAP but am getting the same results. I can get it to authenticate based on overall domain membership but can't seem to figure out how to check group membership.
We've updated to ASA 8.2(1) and ASDM 6.2(1). It seems to have more LDAP functionality but I'm not an LDAP expert. I've posted an image of the LDAP server dialog from the ASDM. I originally tried putting the Group DN in the Base DN field but kept getting a "can't find user" error when testing. I also tried adding the group info in the "LDAP parameters for group search" field at the bottom. But it doesn't seem to be looking there. Note that the current value is the Group Base DN only. I also tried putting "memberOf=" in front of that. Still no luck. The values shown in the image work for simple domain membership.

We have Nexus7009 at client network but due to limitation of Nexus switches that they can not be directly integrate Nexus with RSA so client has purchased cisco ACS for the AAA. We are able to do the authentication and authorization via ACS.However clients wants to further integrate the ACS with RSA so that authentication should happen via RSA and authorization should happen ACS. Is that possible ? if yes, how can i configure the ACS ?
