IP address assisgnment w/ Secure ACS

I have been trying to set up a switch to do the following:
1) Use 802.1x port level authentication
2) Assign VLAN to the client based on username/group
3) Assign IP address to the client
I am using 3750 switches w/ IOS ver 12.2.25 and ACS server ver 3.3.
The port based auth and the vlan assignment works fine, but I cannot get the ip assignment to work. The result is the same if I use Microsoft IAS as the radius server instead of ACS. Is there anything else I should do to get this to work?
Thanks..

I did some research and found that ipaddress assignment is not supported by 802.1x .
IEEE 802.1X does not provide a mechanism for IP address assignment. Therefore the Framed-IP-Address and Framed-IP-Netmask attributes can only be used by IEEE 802.1X Authenticators that support IP address
assignment mechanisms. Typically this capability is supported by layer 3 devices.
More specially :"attributes can only be used by IEEE 802.1X Authenticators that
support IP address assignment mechanisms"
IMO, that means these "IP address assignment mechanisms" are *not* 802.1X but could for example be ppp, pptp, l2tp,...

Cisco Secure ACS

Hi all,
With the Base license, a Cisco Secure ACS 5.6 appliance or software virtual machine can support the deployment of up to 500 network access devices (NADs) such as routers and switches. These are not authentication, authorization, and accounting (AAA) clients. The number of network devices is based on the number of unique IP addresses that are configured.
So, when i have 1 firewall for vpn gateway, and using acs as an aaa server, how much network access device which is counted ? 1 or as many as vpn client connected to the firewall ?
500 network access device means concurrent connection or not ?

ACS is based on the number of NADs (Network Access Devices) like switches, routers, ASAs, etc. So in your example, your Firewall will consume 1 license regardless of the total number of VPN sessions.
With ISE, the licenses are based on the total number of endpoints. So in your example, each VPN session will take a license.
I hope this helps!

Cisco Secure ACS - change ip

Hi all,
another question, we have a Cisco Secure ACS appliance here, and would like to change its ip address, based on Cisco doc, this can be done thru the console, but we’re unable to login thru console, Below is the appliance info. any input would be appreciated.
Application Versions
Cisco Secure ACS              3.3.1.16
Appliance Management Software            3.3.1.16
Appliance Base Image    3.3.1.6
CSA build 4.0.1.543.2      (Patch: 4_0_1_543)
-YL

If you are unable to login through the console make sure the baud rate is set to 115200 and then try again.
Also using hyperterminal instead of putty helps alot also.
Thanks,
Tarik

Cisco Secure ACS license question.

On the Cisco ACS server under the internal identity stores… is “users” and “host” counted against the "base server license" or “network device license”?

Guess you are running ACS 5.x
With the Base license, Cisco Secure ACS 5.3 appliances or software virtual machines can support deployments of up to 500 network devices (authentication, authorization, and accounting [AAA] clients). The number of network devices is based on how many unique IP addresses are configured. This is not a limit for each individual appliance or instance, but a deployment-wide limit that applies to a set of ACS instances (primary and secondary) that are configured for replication.
The optional Large Deployment add-on license allows a deployment to support more than 500 network devices. Only one Large Deployment license is required per deployment as it is shared by all instances.

OS Lion of Apple don't authentication in the Secure ACS

Hello my friends!!!!
I'm with one problem, my OS Lion don't authentication in the Secure ACS Version: 5.2.0.26.10.
For the Mac Lion operating system to work you must put in execeção the MAC Address of your computer. I wonder how it could cause the OS to authenticate the ACS Lion.
Thank you!

Hi,
Are you using wpa2 authentication, also are you using MAR (machine access restrictions) in your global dot1x configuration? If that is the case, then you will not be able to authenticate. Please describe a little bit more about your issue.
thanks,

Unauthorized device logging in via Cisco Secure ACS 3.2

We have the Cisco Secure ACS v 3.2. There is a devices that we recently discovered is not added into the network configuration on the ACS. This device running IOS 12.2(29) does have all of the correct tacacs settings that should allow it to authenticate via Tacacs.
So basically, the ACS is allowing users to use this device to login, even though it's not in the Network Config.
When we look at the Logged-in Users report, it show the host name as "Tacacs+ Default". We aren't sure what that is supposed to mean, and why it's allowing it.
Thank You for your time,
Andrew

Andrew,
Make sure that you not using any Wildcards inplace to IP address in network configuration. Eg using 192.168.*.*
This will open tacacs request from whole network 192.168
Also check the passed attempts and check the NAS IP address from the where the request is coming. Search for that IP in network configuration and see if that IP belong to that switch in question. L3 switch can have multiple ip address.
If that IP belong to that swtich , then you need to take that out from network configuration.

With Cisco Secure ACS For Windows TACACS+, authentication fails with AD

I am setting up a Cisco Secure ACS 4.2 server to act as a TACACS server for Switches and Routers I am using Windows 2003 server for the ACS,
and a Windows 2003 Active Directory server. The AD server is fine, as it is used for many other things.
I have set up ACS as defined nit he installation guide, including all the steps in the 'Member Server' section of the install guide
when using AD as an external database (i.e. setting up the services to run with a domain admin account, setting up a machine called 'CISCO'
on the domain etc).
I've set the unknown user policy to use the Windows database if the internal database doesn;t contain the user details.
If I add a user to the internal database, the authentication goes through fine, with an entry in the 'Passed Authentications' log,
02/24/2010,05:07:03,Authen failed,eXXXX,Network Administrators(NDG) ,X.X.X.X,(Default),Internal error,,(geting error message as INternal Error)
I've scoured google etc, and just cannot come up with any reason why this should be happening.
I've followed all the install guides to the letter. I need to get this up and running as soon as possible,
so am looking forward to finding out if anyone can help me with this one!
THanks and regards
Sharan

Hi Jesse,
Thasts a great answer and Soution.
My previous version was 4.2 and it was installed on 64 bit machine hence getting internal Error.
After this answer i have upgraded it to ACS4.2.1 and its started working fine
Thanks very much for the help

Setting privileges in Cisco Secure ACS Version 5.1.0.44

I am setting privileges in Cisco Secure ACS Version 5.1.0.44.
In the command sets from the ACS server, I denied few commands as can be seen in the attached screenshot and selected 'Permit any command that is not in the table below'.
I am unable to see some commands like "Show running-configuration" from the router I was testing. What changes should I do to see all the commands other than the denied commands. Your help will be rated. Thank you.

Hi,
The ACS is able to handle permit or deny commands.
I created a configuration example that will help you to understand command shell.(see attach doc)
Instead of using show running-config please use show config.
also make sure that all the users are using privilege 15.

Secure-ACS: Special RADIUS-Attributes for Enterasys E7

Hi,
we were running a pretty old version of the Cisco Secure ACS for AAA our network devices.
Unfortunately the server crashed an we had to install and set it up with a new server.
Using TACACS+ for our Cisco devices works fine.
We have a couple of switches made by a vendor called Nexans, which only support RADIUS - this works fine too.
Furthermore we still have some Enterasys E7 and with those RADIUS doesn't work at all.
Sniffering the packets, everything looks good.
With the old server it worked well.
Does anybody know if there are special configurations (e.g. attributes) when configuring an ACS for Enterasys RADIUS-Clients?
Thanks,
Rolf

We have this configuration and works fine with our network and associate in a good manner also the policy which we have configured it on Enterasys in this way
Filter-Id===>
Enterasys:version=1:mgmt=su:policy=Administrator
After we make the update to ACS 5, the "ASA" consider this filter-id as access-list so it consider the field after the filter-id as the name of the acl, and diconnect the VPN connection.
Could soneone help me to resolve that.

EAP-TLS witch Cisco Secure ACS

Hi everyone,
we have implemented wpa/leap in our WLAN. We would use certificates for machine authentication. There is a Cisco Secure ACS Server 3.3 installed.
Is it possible to use the ACS self generated certificate without a CA ?
The examples I found on the web describes only the configuration with CSACS with Microsoft CA.
http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_user_guide_chapter09186a0080205a6b.html
We use Cisco AP1231/AP1232 with 12.3.4JA.
I think for machine authentication we have to install a CA. Let me know, how you think about that issue.
Armin

There are no much options on Client side: MS PEAP, EAP-TLS, EAP-MD5. ACS version 3.3 can generate self-signed certificate (for itself) without the need to install separate CA server. So I'd recommend you to use MS PEAP (PEAP MS-CHAPv2) with self-signed certificate on ACS.

Patch rollup for Cisco Secure ACS 4.2 fails.

I've got 2 freshly installed ACS 4.2 for Windows servers and I need to apply the latest patch rollup before I build the configurations. I stopped the ACS services and ran Acs-4.2.0.124.15-SW.exe to install the patches. The application begins running fine but fails on upgrading the database and then none of the ACS services would start. I was able to restore the files from the backup that runs with the patch utility and get ACS functioning again. What am I missing - does the patch rollup require any specific Microsoft Patches to be installed or something like that?
Thanks

Thanks for the feedback. I attempted the patch rollup install again and it failed in the same place - on the database upgrade. I did think of one thing. Do I need to have my antivirus/protection services disabled prior to installing the rollup?
Also my versions are as follows:
Server OS - Windows Server 2003 R2
Cisco Secure ACS - 4.2.(0) Build 124
Thanks,
Richard Jaehne

Cisco Secure ACS with UCP assistance and enable password

I am running Cisco Secure ACS version 4.2 running on a
Standalone Windows 2003 Enterprise 2003with the lastest
windows service pack and update. Secure ACS is running
fine and I can authenticate with Cisco routers and
switches. The Windows 2003 server is also running Microsoft
IIS Server. In other words, the IIS server and Cisco
Secure ACS is running on the same windows 2003 server.
I am trying to get Cisco User-Changeable password to work
with Cisco Secure ACS. I followed the release notes lines
by lines and the work around provided below:
Also server require more privileges for the internal windows user that runs CSusercgi.exe.
The name of the windows user that runs UCP is IUSR_<machine_name>.
Workaround steps:
1) Install UCP 4 on a machine that runs IIS server.
2) Open IIS manager
3) Locate Default Web Site
4) Double click on the virtual name 'securecgi-bin'
5) Right click on CSusercgi.exe and choose Properties
6) Choose 'File Security' tab
7) Choose 'Edit' in 'Authentication and access control' area
8) Change username from IUSR_<machine_name> to 'Administrator' and enter his
password (make sure that 'Integrated Windows authentication' is checked)
I still can NOT get this to work. I got this error:
It says:
The page cannot be found
The page you are looking for might have been removed,
had its name changed, or is temporarily unavailable.
HTTP Error 404 - File or directory not found.
Internet Information Services (IIS)
I modified everything in the Windows 2003 to be "ALLOWED" by
EVERYONE. In other words, there are NO security on the windows 2003.
It is still NOT working.
The other question I have is that can Cisco UCP allow user
to change his/her enable password?
Can someone help? Thanks.

Yes bastien,
Thank you.
But one thing more i want to know that in its Redundant AAA server, when i try to open IIS 6.0 window 2003; it prompts for Username and Password.
I've given it several time; also going through Administrator account with administrative credentials but it always failed.
Any suggestions/solution/?
This time many thanks in advance.

With Cisco Secure ACS 4.2 User accounts gets locked at first instance of wrong credentials even if configured for 3 attempts

Hello Everybody,
I am working with Cisco Secure ACS 4.2 and it is integrated with Active Directory at a Windows 2008 R2 functional level, user accounts that are set with lockout parameters (3 incorrect attempts) are locked out prematurely after the user enters the wrong credentials just once, the integration is done via LDAP.
I wonder if anybody has any idea why this is happening, because when I connect to a Cisco device or VPN, and type my password wrongly, on the Active Directory I get extra bad password counts.
Thanks in advance and regards....

Hello Scott,
Thanks for your answer. However we checked the ACS logs and it shows that we entered bad credentials just once, but in the Active Directory our account sometimes is blocked because we get at least 2 and sometimes 3 failures. This problem is only presented when we authenticate Cisco devices or through VPN, in normal circumstances, when users enter bad credentials on their computers, it works fine.
Thanks and regards...
