ACS 5.3 and Command Auth

I am rolling out the Latest 5.3.0.40.6 patched ACS 1121 in a redundant pair mode. I have build user based auth without issue but am having an issue with Command auth. once I add command auth to the test router and modify the shell profile and command set for privilege 1 nd 15, none of the commands are authenticated and the report indicates the "DenyCommand" default. I have followed the user guide and the step by step from Security Solutions. ( link below)
I still get no joy. Also Cisco changed the GUI and the way command sets are built
(http://www.security-solutions.co.za/Cisco-ACS-5.2-Role-Based-Authentication-Authorization-For-Different-Privilege-Levels-Configuration-Example.html )
Any help would be appreciated

Tarik, thanks for the response. I cannot get screen shots but can define the options sets.
I created 2 command sets
Pri-15 has only the permit all command not in the table below check box checked
Pri-1 has a single permit "show" with no arguments
the Auth rule has 2 rules
rule 1 identity group "network Admin" any any any pri-15
rule 2 identity group "network monitor" any any any pri-1
service selection rule rule 1 condition ( match system: protocol match TACACS) result Default Device Admin hit count 98
the report indicated the a FAIL "13025 command failed to match a Permit rule) and the Selected Command Set = (DentAllCommands)
So it looks like the command set is not being recognized. but I cannot see why?
Thanks,
Pat

1200, ACS 3.1 and EAP Auth Problem

Hi,
I try configure LEAP auth with ACS using local database. I configures just like say in the Cisco Security Suite 2.0 Doc. For some reason Leap auth sometimes work sometimes don't work. Thanks if anyone could help me.

Is this the document you used? can you share the problems you faced??

Looking for successful auth debug between cisco 1113 acs 4.2 and Active Directory

Hello,
Does anyone have a successful authentication debug using cisco 1113 acs 4.2 and Active Directory? I'm not having success in setting this up and would like to see what a successful authentication debug looks. Below is my current situation:

The 1113 acs failed reports shows:
External DB is not operational
thanks,
james

Hi James,
We get External DB is not operational. Could you confirm if under External Databases > Unknown User Policy, and verify you have the AD/ Windows database at the top?
this error means the external server might not correctly configured on ACS external database section.
Another point is to make sure we have remote agent installed on supported windows server.
http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_solution_engine/4.2/installation/guide/remote_agent/rawi.html#wp289013
Also provide the Auth logs from the server running remote agent, e.g.:-
AUTH 10/25/2007 15:21:31 I 0376 1276 External DB [NTAuthenDLL.dll]:
Attempting Windows authentication for user v-michal
AUTH 10/25/2007 15:21:31 E 0376 1276 External DB [NTAuthenDLL.dll]: Windows

802.1x Machine and User Auth Vlan assignments

I have machine and user auth working between Win2K PC and ACS 3.3 but not sure how to best use the Vlan assignment feature. I use Vlans for different departments and if I assign a vlan in ACS to a machine when it authenticates but the user is assigned to a different Vlan, I don't get a renewed IP.
Here is how it's working now:
1. Machine authenticates to ACS and assigned to a Vlan
2. User logs in and if they are assigned to the same Vlan as the machine, works fine. If assigned to another vlan, the switchport does get changed but the PC still has an IP from the initial Vlan it was assigned to. Releasing and renewing doesn't work but I really don't expect it to.
So, I figure the solution to this is just not set a per user vlan and only set it per machine. But, the group mapping in ACS looked like a great way to assign Vlans based on a user's Active Directory group but it doesn't appear to recognize the different computer OU's we have. So I can assign vlan's based on user groups but not computer groups. As machines are added to ACS, I could change them to an ACS group with the Vlan set but this would be a lot more work than an automated method like unknown user policy.
So, how are others assigning machines to vlans in large multi-vlan networks using ACS and 802.1x?

By default users and computers belong to different global groups. "Domain Users" vs. "Domain Cmpouters" for example.
As for your example, it seems like you have a misbehaving supplicant, and authentication is attempting and then timing out and starting over .. that never actually gets to fail, so the auth-fail stuff won't help.
Note: A good way to troubleshoot this is to notice it in action via show command:
Here's an example of what you should see on a switch port.
AuthSM State = State of the 802.1X Authenticator PAE state machine
VALUES:
AUTHENTICATED -- Auth Succeeded
AUTHENTICATING -- Auth is attempting
CONNECTING -- Dot1x is up and configured and trying to locate a supplicant.
HELD -- Auth probably failed.
BendSM State = State of the 802.1X back-end authentication state machine
VALUES:
IDLE -- Nothing is happening.
REQUEST -- Switch sent some EAP data to AAA, and is waiting to get something back.
RESPONSE -- AAA sent the switch back some data, and the switch in turn asked the supplicant for more data.
NOTE: You should rarely see the RESPONSE state above. If you see it for more than a second or so i nthe middle of an auth attempt, that's a smoking gun that you might have a mis-behaving supplicant, b/c it shouldn't take that long to send an EAPOL frame. The switch will eventually time out, and start auth over.
Hope this helps,

Does XI support FTP over SSL with Command AUTH TLS??

Hi All,
Can we change Command AUTH TLS to AUTH SSL in the Command Order of receiver FTP adapter when you select FTPS (FTP using SSL/TLS) for Controal and Data Connection??
We are able to transfer business documents to bank's FTP server (Following RFC 2228 standards) using WS FTP Pro (I think follows RFC 959 and 1123 standards) which using AUTH SSL in Command order.
We did go through SAP note 821267 (FAQ for XI 3.0 / PI 7.0 File Adapter)...question number 33 address about the "AUTH TLS" command. But we not getting the same error. We get different as in this forum:
Re: Error: Message processing failed: FTPEx: PBSZ=0
Can someone please confirm if this is the issue with FTP RFC standarads?? Or can we coustomize FTPS adapter to send AUTH SSL command??
Thank you,

Dear Andy,
I am also looking for the same information.
Could you please share with ,if u have got anything related....
Hi Experts,
Pls share your exp with us if u have any....

Win 7 client with machine and user auth stuck in 802.1x_REQD

Hi everybody
we have a WLC 5508 with 7.2.110.0 and an ACS 5.3 and do the following:
- Win 7 client gets a GPO object with the wlan configuration for "Machine and User authentication" with PEAP
- On ACS 5.3 I configured correctly the authentication and authorization for first machine authentication and then user authentication ("Was machine authenticated = true)
- First when machine authentication happens, the client is configured into a quarantine VLAN, where it is only allowed to communicate with the domain controllers
- When the user authenication happens, the client is moved into the productive client vlan with no restrictions.
Everything works fine, except that after the user loggs in, it takes about 3 minutes until the client answers the EAP Identity Request and loggs in, see attached screenshot or the screenshot below:
In the client status on WLC i can see that the client is stuck in the 802.1x_REQD state for these 3 minutes, until suddenly it authenticates (but then very often, about 5 times - see screenshot).
We tried the following to find the problem spot. but we were not able to locate the problem:
- Configure the machine and user authentication into the same vlan all the time
- ONLY user authentication on the client
- Played with the Win 7 settings (timers, and so on)
- When we manually configured the WLAN profile on the Win 7 client and saved it, the Win 7 client connected to the SSID without any problems and without any delay (about 5 seconds after the save)
Did someone ever had the same issue?
Thanks a lot and best regards
Dominic

Hi Amjad
very good point on this, thanks a lot. In this case, I did not even think about the client firmware side, thought that I should be the WLC or the client settings, but not the driver. We will give a shot on this next week, maybe this will help us to solve the problem.
It is normal to have the clietn in 802.1x_REQD if it is not yet authenticated and that is the expected state to be at in your situation untlil the client fully authenticates.
Absolutely correct that the client is associated and in the 802.1x_REQD state as long as the authenticator did not get the EAP identity Response, but that the client takes such a long time to answer is not normal ;-)
- What is the supplicant that is used on the windows machines? default WLAN supplicant? or you use some commercial supplicants?
WZC.
- what is the result when testing with user auth only?
The same, it takes such a long time.
- what ist he result when testing with machine auth only?
Machine authentication works as expected, fast and as soon as the client is booted, the client gets authenticated.
Regards and have a nice weekend
Dominic

Dacl on ACS 5.1 and Catalyst switch 3560

Dear all
I have ACS 5.1 and Catalyst switch 3560 with version 12.2(53)SE. I configure a dacl on the ACS and I use it on authorization profile.
This authrization profile is used on access policy.
I tried the authentication but it doesn't work. I checked the ACS logs and I found that the user is authenicated successfuly but the dacl gives this error (The Access-Request for the requested dACL is missing a cisco-av-pair attribute with the value aaa:event=acl-download. The request is rejected)
Steps:
11001 Received RADIUS Access-Request
11017 RADIUS created a new session
11025 The Access-Request for the requested dACL is missing a cisco-av-pair attribute with the value aaa:event=acl-download. The request is rejected
11003 Returned RADIUS Access-Reject
DACL:
deny ip host 1.2.3.4 1.2.3.0 0.0.0.255 log
permit ip any any log
Thanks on advance,

Dear Tiago
I applied the command "radius-server vsa send". Now I can see the dacl is applied but I can't see it on the switch and even the authentication is succueeded ont the ACS logs but it give me unauthoized on the switchport. You can see the logs( started with the username acstest and the access-list is applied but it doesn't work and you can see theat it goes for mab after eap timed out). I hope you can help on this issue.

Guest WLAN and Web Auth?

Hi Guys,
Maybe someone can help me out?
I just finished setting up a trial "Cisco Virtual Wireless Controller" with nearly the same configuration as our Physical
"Cisco Wireless Controller" with the exception of having 2 ports. Anyhow, I managed to get everything working except for the WEB AUTH on the Guest WLAN. When a client connects, he gets a DHCP address from our ASA but when we try to get to a website, we never reach the WEB AUTH page.
What I tried so far is..
add a DNS Host Name to the virtual interface and assign it to our internal DNS server.dns name was resolving but we were unable to ping 1.1.1.1
changed the virtual ip from 1.1.1.1 to 2.2.2.2 and modified the DNS entrydns name resoved but still could not ping 2.2.2.2(I think this is normal)
changed the virtual IP to a private address of 192.168.102.1 and modified the dns entrysame result
I've attached some screenshots of our configuration.

Troubleshooting Web Authentication
After you configure web authentication, if the feature does not work as expected, complete these
troubleshooting steps:
Check if the client gets an IP address. If not, users can uncheck
DHCP Required
on the WLAN and
give the wireless client a static IP address. This assumes association with the access point. Refer to
the
IP addressing issues
section of
Troubleshooting Client Issues in the Cisco Unified Wireless
Network for troubleshooting DHCP related issues
1.
On WLC versions earlier than 3.2.150.10, you must manually enter
https://1.1.1.1/login.html
in
order to navigate to the web authentication window.
The next step in the process is DNS resolution of the URL in the web browser. When a WLAN client
connects to a WLAN configured for web authentication, the client obtains an IP address from the
DHCP server. The user opens a web browser and enters a website address. The client then performs
the DNS resolution to obtain the IP address of the website. Now, when the client tries to reach the
website, the WLC intercepts the HTTP Get session of the client and redirects the user to the web
authentication login page.
2.
Therefore, ensure that the client is able to perform DNS resolution for the redirection to work. On
Windows, choose
Start > Run
, enter
CMD
in order to open a command window, and do a nslookup
www.cisco.com" and see if the IP address comes back.
On Macs/Linux: open a terminal window and do a nslookup www.cisco.com" and see if the IP
address comes back.
If you believe the client is not getting DNS resolution, you can either:
Enter either the IP address of the URL (for example, http://www.cisco.com is
http://198.133.219.25)
♦
Try to directly reach the controller's webauth page with
https:///login.html. Typically this is http://1.1.1.1/login.html.
♦
Does entering this URL bring up the web page? If yes, it is most likely a DNS problem. It might also
be a certificate problem. The controller, by default, uses a self−signed certificate and most web
browsers warn against using them.
3.
For web authentication using customized web page, ensure that the HTML code for the customized
web page is appropriate.
You can download a sample Web Authentication script from Cisco Software Downloads. For
example, for the 4400 controllers, choose
Products > Wireless > Wireless LAN Controller >
Standalone Controllers > Cisco 4400 Series Wireless LAN Controllers > Cisco 4404 Wireless
LAN Controller > Software on Chassis > Wireless Lan Controller Web Authentication
Bundle−1.0.1
and download the
webauth_bundle.zip
file.
These parameters are added to the URL when the user's Internet browser is redirected to the
customized login page:
4.
ap_mac The MAC address of the access point to which the wireless user is associated.
♦
switch_url The URL of the controller to which the user credentials should be posted.
♦
redirect The URL to which the user is redirected after authentication is successful.
♦
statusCode The status code returned from the controller's web authentication server.
♦

All the files and pictures that need to appear on the Customized web page should be bundled into a
.tar file before uploading to the WLC. Ensure that one of the files included in the tar bundle is
login.html. You receive this error message if you do not include the login.html file:
Refer to the Guidelines for Customized Web Authentication section of Wireless LAN Controller Web
Authentication Configuration Example for more information on how to create a customized web
authentication window.
Note:
Files that are large and files that have long names will result in an extraction error. It is
recommended that pictures are in .jpg format.
5.
Internet Explorer 6.0 SP1 or later is the browser recommended for the use of web authentication.
Other browsers may or may not work.
6.
Ensure that the
Scripting
option is not blocked on the client browser as the customized web page on
the WLC is basically an HTML script. On IE 6.0, this is disabled by default for security purposes.
7.
Note:
The Pop Up blocker needs to be disabled on the browser if you have configured any Pop Up
messages for the user.
Note:
If you browse to an
https
site, redirection does not work. Refer to Cisco bug ID CSCar04580
(registered customers only) for more information.
If you have a
host name
configured for the
virtual interface
of the WLC, make sure that the DNS
resolution is available for the host name of the virtual interface.
Note:
Navigate to the
Controller > Interfaces
menu from the WLC GUI in order to assign a
DNS
hostname
to the virtual interface.
8.
Sometimes the firewall installed on the client computer blocks the web authentication login page.
Disable the firewall before you try to access the login page. The firewall can be enabled again once
the web authentication is completed.
9.
Topology/solution firewall can be placed between the client and web−auth server, which depends on
the network. As for each network design/solution implemented, the end user should make sure these
ports are allowed on the network firewall.

For web authentication to occur, the client should first associate to the appropriate WLAN on the
WLC. Navigate to the
Monitor > Clients
menu on the WLC GUI in order to see if the client is
associated to the WLC. Check if the client has a valid IP address.
11.
Disable the Proxy Settings on the client browser until web authentication is completed.
12.
The default web authentication method is PAP. Ensure that PAP authentication is allowed on the
RADIUS server for this to work. In order to check the status of client authentication, check the
debugs and log messages from the RADIUS server. You can use the
debug aaa all
command on the
WLC to view the debugs from the RADIUS server.
13.
Update the hardware driver on the computer to the latest code from manufacturer's website.
14.
Verify settings in the supplicant (program on laptop).
15.
When you use the Windows Zero Config supplicant built into Windows:
Verify user has latest patches installed.
♦
Run debugs on supplicant.

16.
On the client, turn on the EAPOL (WPA+WPA2) and RASTLS logs from a command window, Start
> Run > CMD:
netsh ras set tracing eapol enable
netsh ras set tracing rastls enable
In order to disable the logs, run the same command but replace enable with disable. For XP, all logs
will be located in C:\Windows\tracing.

AP350 with LEAP and MAC-Auth

Hi,
is there any solution for this?
I'd like to do LEAP and MAC-Auth with Microsoft IAS-Server instead of Cisco ACS.
With ACS everything works fine but i have to buy the licences. For IAS i already have them but always 'EAP authentication method is unrecognized'.
The clients all use W2K Prof.- no XP anywhere, so i can't go to EAP-TLS.
thanks in advance
Thomas / Networking admin

Sorry, but LEAP is today only available on :
Cisco Secure ACS
Cisco Access Registrar
Funk Software Radius
Interlink Radius

Question in ACS radius ports and how test connectivity between router

hi all
im asking here about default ports used in cisco acs for radius protocol
is it 1812 and 1813 ???
or there is another ports ??
Q2-
how to test connectivity between ACS "server aaa" and the router "client aaa " ??????
Q3-
can anyone give me simple config on router for radius protocol to connect acs based on radius protocol ?
regards

The default authentictaion port is 1812 and the default accounting port is 1813.
Here's an example config-
aaa new-model
aaa group server radius ACME-RADIUS
server-private 192.168.1.5 auth-port 1812 acct-port 1813 key SeCrEtPaSsWoRd
aaa authentication login default local
aaa authentication login ACME-AAA group ACME-RADIUS local
aaa accounting send stop-record authentication failure
aaa accounting exec default start-stop group ACME-RADIUS
line vty 0 4
login authentication ACME-AAA
You can test with-
test aaa group radius server 192.168.1.5 mmessier St@nleyCup
where mmessier is your username and the password is St@nleyCup

WLC / ACS / AD - Domain and non-Domain Laptops (802.1X / PEAP)

Hi All,
I'm implementing a solution based around 4404 WLC, 1113 ACS and Microsoft AD. What I want to achieve is have two WLAN (SSID), one that can only be used by domain users on domain laptops, the other can be used by domain users on personal laptops. The domain laptops will have full connectivity but the personal laptops will be restricted.
I've created the two SSID using 802.1X via ACS / Remote Agent and can authenticate and logon OK.
I thought that I should have user auth and machine auth for the domain laptops but just user auth for personal laptops.
I can have non authenticated machines go to a specific ACS group or blocked but I need to allow them if they're on the restricted SSID. I can't quite figure out how to have two SSIDs authenticating to the same ACS / AD - allow one and block the other.
Am I on the right path?
Anyone done this before or have any bright ideas?
Cheers,
John

With the use of SSID-based WLAN access, the users can be authenticated based on the SSID they use in order to connect to the WLAN. The Cisco Secure ACS server is used to authenticate the users. Authentication happens in two stages on the Cisco Secure ACS:
1. EAP authentication
2. SSID authentication based on Network Access Restrictions (NARs) on Cisco Secure ACS

ACS Tacacs+ aaa authorization commands

Hi,
I would like to authorize only certain configuration commands by the Tacacs Server, so in the group setup of ACS, I have checked : command, I have written in the field : configure, and declared as arguments : permit terminal and permit snmp-server enable traps. But I can not configure snmp until I declare in the router : privilege config level 7 snmp-server enable. (I use a level 7 user)
My question is : is there a way to control the granularity of configuration commands on the ACS, in the same way as you can control the granularity of the show commands ?
Many thanks
Patrice

Yes, you can get very granular using Command Authorization Sets and they can be applied to individual users or groups.

Shell Command Auth Question

I'm trying to setup a Shell command auth set for clearing interface counters but I can't think of a way to do so. Is there a way to do something like:
"permit counters interface *"?
TIA

I'm assuming you are using CSACS (not indicated) for defining your command sets.
e.g.:
"Deny" radio button selected (i.e.: only listed commands will be authorized).
Command List:
clear
disable
enable
show
"Clear" command argument(s) set as follows:
(a) Deselect the "Permit Unmatched Args" checkbox.
(b) Enter the following argument(s) into the list:
permit counters
... or, to be more specific:
permit counters Ethernet 0
permit counters FastEthernet 0
This should result in the ability to clear all counters, or the counters of specific interfaces (if you define them).
Notes:
(1) Command arguments are case sensitive and may differ from how they are entered at the CLI.
(2) A sniffer is helpful in determining proper case.
(3) Wireshark is capable of decrypting TACACS+ packets if you configure the application with the password.

Ctrl + e and command + e stopped working

I've seen a few other discussions about ctrl + e not working but none of them fit the problem I'm having here.
On http://www.clarkwfobes.com I have ICE set up. I've been editing before and so has the client so it was working with no problem. Now when I or he goes to the site, ctrl + e doesn't work on his PC and command + e on my mac doesn't work either.
Can anyone shed some light as to why this is happening. when I log into the manage sites section, I can edit from there and see that the client edited something on the site in January 2010.
Thanks in advance for your help!
best,
Leslie

Interesting.
Well this won't hurt and might resolve your issue, it's sort of a "clean out everythng and reset" sort of approach but I find it cleans out the gremlins.
Download the free OnyX and run ALL the cleaning and maintainence steps.
http://www.titanium.free.fr/
You can Cancel the reboots in between.
Lastly use the Verify > Preferences check
Now Reboot the machine.
Another good piece of free software to have is Carbon Copy Cloner, all you need is a external drive and your a simple "hold option" boot off the clone for any emergencies with your boot drive.
