Cisco AAA/Identity/Nac :: ACS 5.3 - External Proxy Service User Logs?
Apr 11, 2012
We are currently using Cisco ACS 5.3.0.40.2. One of the Services Selection Policy it hosts is:
Receive Authentication request from a wireless controller for a wireless userIf the wireless user's username contains a particular domain suffix, the request is proxied to an external proxy server using an External Proxy service (configured for both local/remote accounting)On receiving an Acccess-Accept from the external proxy, the user is given access and ACS 5 will start logging account packets for the username (nothing appears in the RADIUS authentication logs - ACS 5 it seems doesn't log proxied authentication requests) The above setup works fine in most instances. We start to have problems when an external proxy server strips the domain suffix off the username in the Access-Accept packet e.g.
ACS 5 proxies an Access-Request to an external proxy server (with Username = someuser@somwhere.com)The external proxy replies with an Access-Accept (with Username = someuser)The user 'someuser' is given access but subsequent accounting attempts fail because their username (without the domain suffix) doesn't match the Service Selection PolicyIs there any way to get ACS 5.3 to log proxied authentication requests? If not, can I configure ACS 5.3 to use the username in the Access-Request packet (rather than the username in the Access-Accept packet) for accounting?

I have some queries regarding on the report generation for on Cisco ACS v5.2.
1) Can we schedule to run a customized report on ACS and then email the report to the user?
2) Can we run a users authentication trend report based on the AD directory group rather than individual user.
3) Can we configure user authentication logs to be viewed on WCS.

Is it possible to create on ACS5 rule which will:
1. Try to authenticate user in external database1 (radius)
2. When external database1 returns FAIL (because of bad password) ACS5 should try to authenticate user in another external database2 (radius)

I have ACS4 and i am planning to upgrade to ACS5.I would like to have such a rules:I have user1, one ASA device which is VPN concentrator for remote users.ASA have two different tunnel-groups: one which allow for logging via certificate (with mandatory pki authorization thru ACS) with disabled Xauth,and second tunnel-group with allow login thru typical Xauth with authorization thru ACS which users external database (RSA Tokens).So i have one user1 which can login thru VPN using RSA tokencode or certificate.For example: on phone user1 uses certificate, and on PC station the same user1 uses token password.For tunnel-group with pki authorization ASA checks username in ACS and in typical scenario login="CN from certificate" and password="CN from certificate". So we would need "two credentials" for the user - one for pki authorization, and second one external database (RSA token).Is such scenatio possible under ACS 5 ? where one user uses different credentials based on tunnel-group usage ?

I have an ACE4710 with a few basic farms running and it works great however I now need to implement an SSL proxy service for the first time. The requirement is that clients who are already using FQDN's need to be sent to diffent real server IP addresses as each client will have their own VM. All the clients will use the same global IP address with different A records.

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 have a cable modem internet connection and my cable modem is connected to an ASA 5505. The inside interface of the ASA has an IP address of 192.168.2.2 and is connected to a Linksys router's internet port which has an IP address of 192.168.2.1. The Linksys router then has a local area network of 192.168.1.0 and all my clients are on that network. Everything is working fine except in my ASA logs all the traffic shows up as the router's external address which is 192.168.2.1. I would like to see the 192.168.1.x address of the clients in the ASA firewall. I've tried making some changes to the Linksys router but that hasn't resolved it. Is there any changes I can make on the ASA to get this to work?

How can I tell if the ATT Data Service on my iPad is going through an ATT Carrier Grade NAT router or proxy server? Why I can't tell.
1. iPad does not have an interface that shows the assigned address on the Data Connecton or access to any terminal commands.
2. The reported ATT (Cingular) address is 166.147.103.208 if you use a What-Is-My-IP type of service. On a Verizon (not ATT) iPad I can ping all the way back to the iPad and turning the iPad off stopped the Ping Response . . . but there is no answer when I ping the ATT iPad 166.147.103.208 and Trace Route to the iPad stops answering at the border of the ATT network.
3. If I make a page request on an IIS web server from the ATT iPad, the web server logs 166.147.103.208 (see above) as the source address and logs the iPad as the source device, but 166.147.103.208 could still be an ATT proxy, not the iPad because some NAT routers change the source IP address to themselves.
We want to use an ATT Hotspot as the the permanent always-on home internet service where there is no other option (except satellite). We need dynamic DNS at the home, and that requires a routable public address on the ATT-hotspot. We are guessing the iPad and HotSpot would be using the same ATT network.So how can I tell if the iPad has an ATT address that can be reached from the internet (no proxy's or carrier grade NAT routers)

Goal: To forward requests over port 80 from my LAN to an external server on a specific port, that is I would like to forward all requests over http to an external proxy.
I know that this can be done with IP-Tables, but I would like to do the same thing with my D-Link. I have looked at Advanced --> Routing, but that seems to be specifically for inbound requests. I want to do this for outbound requests. This can be achieved with the D-Link DIR-655?

I want to redirect internal web traffic (browsing) to an external web server for Web, Virus and Spyware filtering. Those externals proxies are running in 8080 port. I have one ASA firewall and a Cisco 2600 router. I was thinking in doing PBR in the router but in the next hop I can only set one IP, not an IP and a port. So how can I redirect web traffic to an external proxy listening in 8080 port?

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 have 3 ACS servers placed throughout N. America. I it set up so that ACS01 is primary and ACS02 and ACS03 are secondary. When i look at the logs for passed/failed authentications in radius or tacacs I cannot see anything from ACS03 logging. This is weird because just a few weeks ago it worked perfectly. In fact, ACS03 is the most active server since this site is using it for wireless phones and tacacs and the other 2 are just using ACS for wireless networking. I went through the log settings and every server is set up the same as the others (except the primary) so it should be logging ACS03 the exact same as 01 and 02.Anyway it seems like a small problem but i need the logs to work correctly to properly administrate security.

I'm trying to get a solution together for a dial backup to an ADSL service, using an Analogue modem.The kit list is as follows:
Cisco 877
Multitech MT5656ZDX External Analogue Modem or USR 5630D External Analogue Modem
Rolled patch cable RJ45 to DB25M adapter (pinout from a cisco guide)
So far I am unable to get the router/modem to dial out at all. I know the modems work, I have tested them from Windows.
I have attached a couple of outputs from "show line" and "show line 1" from the router and also what I think are the relevent lines of config although it will be too much config and probably jumbled by now as I've tried quite a few things to try and get this working.
I am more concerned with the config relating to the connection of the analogue modem than the routing element.

We recently had to rebuild our ACS server. Now when we have an 802.1x authentication failure and look at the RADIUS logs for the specific user, it does not show us the MAC address of the device the user tried to login with. We use this all the time because users have PDAs and other mobile devices that they save their passwords on. Then when they change their domain password on their laptop, they don't change it on their PDA which then tries to authenticate them using the wrong password and eventually locks them out. We need to see the MAC address so we can pinpoint which device is causing the lockout. The report I am generating is when you go to this location: Monitoring & Reports > ... > Reports > Catalog > User > User_Authentication_Summary

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 have problem with ACS 5.0 on reporting. On "Monitoring and Report" page in Faverite Reports when i clicking on "Authentications - RADIUS - Today", My browser displays error "Error while reading skin-access.config. Please make sure the file exists and conforms to the schema specified"
I must also mention that I never upgraded the version of ACS from 5.0 also from command line all the acs services are running. It is running on CISCO 1120 Secure Access Controll Server apliance.
My second question is can I upgrade the version of ACS to 5.4 with Cisco Secure ACS 5 Base License?

Having an issue where a user will plug a PC into a switch. The switch does a MAB authenticaiton and the MAC is not located in the ACS server. It logs the failed attempt, but when the PC is removed from the switch, the failed attempts keep getting logged until the port is bounced. Any way to keep the attemps from happening after the PC is removed? If not, any way to make it stop without bouncing the port?
running ACS version 5.2.0.26
switch port config:
interface GigabitEthernet1/0/2
sw access vlan 2 sw mode access
authentication control-direction in
authenticaion host-mode multi-auth
authentication port-control auto

I'm using ACS 5.4p2 within distributed systems: one primary and one secondary instance.For now, primary instance is acting as Log Collector server and I can see any AAA audit logs.
When the primary instance fails I can authenticate successfully using the secondary instance.However, when primary instance comes back, I'm not able to see any audit logs operated by secondary.
