AAA/Identity/Nac :: ACS 4.2 - Send RADIUS To An External Site?
Jan 16, 2012
I've got a pair of Cisco ACS 4.2 servers running on our corporate LAN. Currently they are doing TACACS+ for the network gear, and wireless authentications for internal users.
We have contracted with an external web site for an application - They can run RADIUS from their site to our LAN for the user authentications. How can I best do this?
1. NAT the traffic on my ASA firewalls to the internal servers, send the RADIUS traffic to/from the external site?
2. Is this secure?
3. Should I have a RADIUS server in the DMZ instead?
4. Any issues with doing this on ACS 4.2?

Wondering if it's possible to send a VSA from my radius server to my ASA-5505 that will instruct the ASA to use one of several split tunnel lists I have created, based on the user name supplied in the Radius request.For example, I can send a VSA of "ip:inacl#1=permit ..." and the ASA will dynamically create an access-list for that user.Is there a similar VSA for split tunnel?

I am attempting to configure Radius authentication accross a site-to-site VPN for my ASA 5510-01 for remote access.
ASA5510-1 currently has a live site to site to ASA5510-2.
ASA 5510-1 - 10.192.0.253
ASA 5510-2 - 172.16.102.1
DC - 172.16.102.10
ASA5510-01 can ping the DC and vica versa but is unable to authticate when i perform a test. ASA5510-01 can authenticate to a DC on it;s own LAN but not on the remote LAN that DC sits on.
I have double checked the 'Server Secret Key' and ports as well as various users which all work locallly. ASA5510-02 authenticates to DC with no problems.

I have a Sito-to-Site VPN between two ASA 5540 outside interfaces.I'm trying to configure ssh radius authentication on one of them but the Radius server is located behind the other ASA.When I try to connect to this ASA outside interface using my radius credentials, the communication to the radius server goes in timeout.It seems that the ASA doesn't use the crypto map to route the request to the Radius server.

I have a site to site VPN tunnel configured between a rv220w and rv180. Everything works fine going from site to site on LAN connections. I'm now trying to tie in the remote site wireless (rv220w side) by pointing radius to my ACS server which is on the other side of the site-to-site tunnel but it seems as though it doesnt route across the site to site tunnel. If i put a radius server on the local lan on the remote site that authentication works fine. I have confirmed there are no ACL problems. the RV220W capable of using a radius server across the vpn tunnel?

I am looking to port legacy ACS 4.2 "proxy distribution tables" to ISE 1.1.1 and I am currently a little at a loss where to start. I know I have to add the External RADIUS Server, Configure a RADIUS Server Sequence that will skip local authentications then send to the External RADIUS server. How do I match this authentication and how do I match it to an authorization rule? Is this the Network Access:Use Case equals proxy?

I am biulding a wireless network with 5508 WLC and trying to use ISE as radius server and also to redirect the web-login to it.I was trying to understand that to achieve the external web-login, do i need to use the raduius-nac option under advanced on the guest wireless where i am trying this out. and if not, where do i actually use it?So far what i have understood that i do need to have preauth ACL on the Layer 3 security, but the issue is there is no hit reaching the ISE.

We have a 1231 AP and a Freeradius Server.Now we are using MAc authentication.The thing is that the AP sends two parameters to the RADIUS:
User-Name = "000ff855df2e"
User-Password = "000ff855df2e"
both are the MAC of the wireless client.I want that the AP send:
User-Name = "00-0f-f8-55-df-2e"
User-Password = "mykey"
Note that the MAC is dash separated and the password is forced to the key that I want.

I have a new Cisco Secure ACS 5.2 on a VM. We want to use it to for administrative access to our Cisco equipment with TACACS+. I am trying to map user permissions to different groups of devices based on active directory group membership, however it is not working.
I am using an LDAP (configured for secure authentication) external identity store. On the directory organization tab, I have confirmed the accuracy of the subject and group search base and the test configuration button shows that it's finding > 100 users and >100 groups.
On the directory groups page I have entered the groups according to the required format. cn=groupname1,ou=groups,dc=abc,dc=com
I have a rule based result selection under group mapping. I have two rules in the format below.
Conditon
LDAP:Externalgroups groupname1
Result
Identitygroup1
I have the default group set to a identity group named other. My problem is, no matter what user attempts to authenticate, the Default rule is applied, and the user is put into the other identity group.This occurs when I log on as a groupname1 user, groupname2 user, or as user that is not a member of either of those groups. LDAP authentication works and the user is able to logon to the device.

I have installed ACS 5.4 and we are looking to authenticate our Anyconnect users with ACS via Active Directory. I think I have the correct commands in our ASA ( we had ACS 4 and authenticated our anyconnect users ).
I also have configured ACS to use Active Directory and installed the server side cert in ACS. I'm just uncertain how to program ACS to use the security group that I have setup in Active Directory.

I would like to configure the below setup:
End user client (Cisco Any connect/VPN client) -> ASA 5500 (AAA client) -> ACS server -> External RADIUS database.
Here ACS server would send the authentication requests to External RADIUS server.So, i have added the external user database (RADIUS token server) in ACS under External databases.I have added AAA client in Network configuration (selected authenticate using RADIUS(VPN 3000/ASA/PIX 7.0) from the drop down.
Here how do i make ASA recognize that it has to send the request to ACS server. Normally when you use ACS as RADIUS server you can add an AAA server in ASA and test it.But here we are using an external RADIUS server which has been configured in ACS, so how do i make ASA to send the requests to ACS server?

I am currently useing ACS 5.2 and have no problem using Tacacs+ with AD access.
But with Radius it seems I can only get the Local identity store to work, need to do something special to get Radius to work with active directory with Cisco ACS?

Device: 3841
IOS: 15.1(4)M2 ADVSecurity
Commands: AAA Authorization
Commands take approximately 8 seconds to process when required to authorize with ACS. The show run command will take 8 seconds to process then output is displayed.Packet sniff indicates that it takes 8 seconds for the router to send the initial TCP SYN SEQ packet to ACS. Login to device has no delay.

We have to configure our firewall cisco Asa 505 (ASA Version 8.3(1)) in order to establish a ipsec vpn between our office site and another external site. Vpn has been established successfully between our ip site 172.16.69.24 and other vpn ip site 172.16.23.23.Our server (192.168.100.25) behind firewall cisco (sk lan 192.168.100.254) manages to ping server 172.16.23.23 on other site through a static route add on windows so server (route add 172.16.23.0 MAK 255.255.255.0 192.168.100.254).On the other site, server with ip 172.16.23.23 doesn't ping our vpn ip site (172.16.69.24) which has to be natted to our server 192.168.100.25.

We have 2 ACS 4.2.1 servers in Windows 2003 with SP2 installed. We have updated the first ACS to the latest patches for Windows. After that we started having problems. CSRadius either stops by itself or when some time passes we get the following error in Failed attempts "Unknown error". When we restart the ACS services by the GUI, it resumes until the next time it stops.Do you happen to know if we have any bugs related to Windows patches?

I am trying to configure AAA authentication and authorization with Cisco 3725 (IOS 12.4(17)) for 802.1x and ACS 4.2 with VLAN assignment to my Windows XP client. (trying to assign VLAN 100 in my scenario).When user connects to the Router, it passes the authentication process (EAP-MD5). In my debug i see that Router recieves the Radius Attributes BUT does not apply anything!My running config:
Building configuration...
Current configuration : 1736 bytes
!
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
[code]......
As a result the vlan-switch data based does not change.

I am using the Self RADIUS server in my Cisco ACS SE 4.2 appliance S. I have an AAA client C that interacts with S by means of the RADIUS protocol. This works fine, in that S correctly carries out authentication chores on username/password (PAP and CHAP) pairs received from C, sending back to C the corresponding Access-Accept packet when the authentication succeeds, or Access-Reject when it doesn't.
I have been able to import a set of three VSAs into S. Each of those attributes is of string type. I then configured in S a single user U with password P so that, whenever a U/P pair received in S from C is authenticated by S, S should send back to C, in the Access-Accept packet, the three attributes with the following values: [code]
With this setup, when an authentication is successfully completed by S, C receives 53 bytes worth of data from S every time. I am attaching a typical example, already disassembled. I have disguised the actual vendor ID, for legal reasons, but the rest is exactly as it was when received in C.
According to the disassembly, what we got is an Access-Accept packet, as expected. Its length is 53 bytes - again as expected, for this is the only packet that C has received from S here. However, the packet is incomplete, for attribute #3 is missing its value field.
Looking into the whole packet in more detail, it can be seen that while the wire format for the first attribute, namely, Frame-IP-Address, is correctly constructed, the remaining are not. For example, the sequence of bytes corresponding to the attribute #1 reads 1a 09 00 00 xx xx 2c 61 62 63. I believe that this is incorrect; it should be 1a 0a 00 00 xx xx 2c 61 62 63, for the wire format for this attribute consists of 10, not 9, bytes. I tried a few variations on the values for the attributes, and the results are always substantially the same, in that the wire formats for these attributes are always incorrect.
This all probably implies I have done something wrong when importing the VSAs into S, and/or when configuring things on S. I am therefore attaching the csv files I used to import my VSAs into S; as before, names and vendor ID are disguised, but their lengths are exactly the same as in the undisguised file. I used two csv files: One to import the vendor ID, and the other to import the VSAs under that vendor ID. As for user U, in S's administration GUI I clicked on User Setup and selected user U, moved to the bottom of the screen, where the attributes for this particular vendor were present,introduced the values for each attribute mentioned above, and made sure that button in front of each attribute was ticked.

Several of my older netscreen devices only support radius authentication and I'm having trouble migrating them from ACS 4.2 to ACS 5.1. When I try to authenticate, the authentication passes in ACS but it doesn't log you into the Netscreen (you see a auth failure in the Netscreen logs). I believe that the custom attributes are not being passed from ACS to the Netscreen. The custom attribute we are trying to pass is "NS-Admin-Privilege" with type integer and a value of 2. The netscreen is setup so that the user privledges are obtained from the ACS server.
Any setup where they are using Cisco radius authentication to authenticate Netscreen devices?

I was wondering if i should use the same RADIUS VSA attribute on ACS v5.1 to authenticate AAA clients as those i was using on my old ACS v3.3 server.
Example : under ACS v3.3 i was using RADIUS (Cisco Aironet) attribute to authenticate AP & WLC, should i do the same under ACS v5.1 ?
