Authentication in the chain DUN-AAA client-ACS-NMAS-NDS

Dears,
I have installed Novell client on a windows XP.
I will login my user and my password in NDS via the chain cisco aaa client
(router cisco 2503)- acs server - nmas.
For this in the login mask of the novell client, I select Dialup --> login
using dial-up networking --> the profile of my DUN containing the
properties of my modem connection --> no location (direct connect).
When I press OK, it is asking to me the detail of the connection :
- my username
- my password
- my domain
- my phone number
I select connect to inititiate the connection. I late the parameter "my
domain" to empty.
I see that the novell client is using DUN to dialin the correspondant
modem.
I receive the call on my acs aaa client (router cisco 2503)and this aaa
client is sending the packets to acs server for authentication.
Then, the ACS server is receiving these packets and resend these to NMAS
(token radius server external database). Normally NMAS has to authenticate
the user and password inside the NDS.
But I receive an error message indicating that the usename and password
are invalid on the doamin (error code 619).
I don't understand this error message because there is no domain notion in
Novell. I can understand that mircosoft needs a domain to authenticate the
user and password. Because the Novell client dial-up is based on DUN and
DUN is based microsoft, we need a domain for authenticating the username
and password.
Does it mean that I need an Active Directory for authenticating username
and pasword in the domain ?
Does it mean that I have to integrate the AD with NDS ?
Can I use the local AD/SAM of my PC to authenticate the username and the
password in the domain ?
If yes, how can I configure the NDS for this ?
Could you help me as soon as possible ?
Yours sincerely,
Olivier MONTEE.

How to count the number of AAA clients

Hi,
As we know, ACS5.2 is required with a base license-- supporting 500 network devices.
Sometimes there are lots of AAA clients or network devices that are authenticating simultanious. So my question is, how to count the network devices allowed to auth on ACS5.2? Does that only include network devices, or including both any network devices or AAA clients?
Rgds,
Laowu5017

Hi,
ACS 5.x counts the number of AAA clients that are configured on the ACS.
Please note that AAA clients and networks devices is the same and they comply switches, routers, WLCs, or whatever other device configured under
Network Resources >
... >
Network Devices and AAA Clients
AAA Clients are NOT the AAA suplicants.
The end user clients PCs are the AAA suplicants, and for this there is no limit number.

EAP Chaining with Cisco ACS 5.x and the Cisco Anyconnect NAM Client

Hi Guys,
Whilst I’m well aware of the limitations of the built in the windows Wireless 802.1x supplicant. Is there a way, using the NAM client to authenticate both a computer and a user simultaneously, when used for authentication to wireless networks?
As has been posted many times before on this forum, this isn’t possible due to windows not authenticating with the 'computer account' whilst the user is logged in, but with the NAM client it seems possible to do both user and computer authentication based on the options it gives you with EAP-Fast and 'EAP Chaining'.
Can anyone validate this is possible? I have the design guide for exactly this for Cisco ISE but i need it to work on ACS (5.x).
Thanks in advance.
SteveH

Bobby, I ran into the same issue with the "15015 Could not find ID Store" issue. It turned out to be an issue with communication between the ACS and AD. It looked like AD was connected successfully, but until I rebooted ACS, I kept getting the same error. It was like it couldn't see the AD security groups even though it could scan the AD tree successfully.
So, try rebooting ACS if you haven't already and see if that resolves the error.

Configuring AAA network client on ACS v5.1 using the same RADIUS atributes from ACS v3.3

Hello,
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.
Exemple : under ACS v3.3 i was using RADIUS (Cisco Aironet) attribute to authenticate AP & WLC, should i do the same under ACS v5.1 ?
Best regards.

Hello,
When defining AAA client on the new ACS 5.x server you just select TACACS+ or RADIUS. We no longer define the RADIUS "vendor"/"VSA" when creating the AAA Client entry. All AAA client would be defined as RADIUS or TACACS+ only.
If you were using specific VSA Attributes then you need to send those attributes back configuring Authorization Profiles on the ACS 5.x. You will find the specific VSA attributes there. Refer to the following screenshots:
And here are the available attributes for the ACS for RADIUS Aironet:

How to stop ACS intergated AD users to login in AAA clients(network device)

I have ACS 4.2 Appliance which is integrated with Active directory.
AD users are able to login in network devices. Is there any so that I can stop AD user and other local users to login in AAA clinets (network devices).

These types of configurations are a two-way street. ACS must be configured to actually perform the authentication/authorization, and the AAA clients must also be configured for authentication/authorization. I would look at the AAA client configurations, first.
What kind of AAA clients are we talking about? Cisco switches, Cisco WLC's? Swicthing gear from other companies?
For Cisco switches, lines like the following will tell them to use your ACS server for administrative user auth (RADIUS ro TACACS+, respectively):
aaa group server radius rad_admin
server xxx.xxx.xxx.xxx
aaa group server tacacs+ tac_admin
server xxx.xxx.xxx.xxx
If your AAA client is a WLC, then you need to uncheck the "Management" box where the RADIUS server is defined for authentication (Security -> AAA -> RADIUS -> Auth).

ACS 4.2.1: adding new AAA clients through odbc import

Hello,
we have added the user defined vendor RADIUS_HUAWEI to our Cisco ACS 4.2.1 Windows Server.
Unfortunately there is a problem with importing network devices through odbc connection using the accountactions table with the action code 220.
The documentation tells us :
220
ADD_NAS
VN, V1, V2, V3
Adds a new AAA client (named in VN) with an IP address (V1), shared secret key (V2), and vendor (V3). Valid vendors are:
•VENDOR_ID_IETF_RADIUS—For IETF RADIUS.
•VENDOR_ID_CISCO_RADIUS—For Cisco IOS/PIX RADIUS.
•VENDOR_ID_CISCO_TACACS—For Cisco TACACS+.
•VENDOR_ID_AIRESPACE_RADIUS—For Cisco Airespace RADIUS.
•VENDOR_ID_ASCEND_RADIUS—For Ascend RADIUS.
•VENDOR_ID_ALTIGA_RADIUS—For Cisco 3000/ASA/PIX 7.x+ RADIUS.
•VENDOR_ID_AIRONET_RADIUS—For Cisco Aironet RADIUS.
•VENDOR_ID_NORTEL_RADIUS—For Nortel RADIUS.
•VENDOR_ID_JUNIPER_RADIUS—For Juniper RADIUS.
•VENDOR_ID_CBBMS_RADIUS—For Cisco BBMS RADIUS.
•VENDOR_ID_3COM_RADIUS—For Cisco 3COMUSR RADIUS.
The new user defined vendor is:

CSUtil v4.2(1.15), Copyright 1997-2009, Cisco Systems Inc
UDV 0 - RADIUS (RADIUS_HUAWEI)
Our action code and variables look like:
A=220
VN="xxx"
V1="10.10.10.10"
V2="blabla"
V3="VENDOR_ID_RADIUS_HUAWEI"
Error Code is as following:

Does anybody knows the correct name for the V3-variable to import the network device in a correct way?

ACS 5.0 having issues with different subnet AAA Clients

Dear All,
I am getting weird issue. My ACS 5.0 is in subnet 10.1.1.0/24. All the AAA clients which are in the same subnet can communicate with the ACS but different subnet cannot.
I have checked the firewall between them, Its allow any any with all services.
One more thing I have faced today is that now from only one switch (10.1.2.10) can access ACS but switches in the same subnet (10.1.2.0/24) cant access ACS as same previous issue.
Following are the logs of one switch(10.1.2.10) in different subnet can access ACS :

Waiting for your responses.

Ok, cool,
So this usually means that the switch is sourcing the requests from a difernet interface that is configured on the ACS.
I would guess that the ACS is reporting unknown NAS...
Can you please use the "ip tacacs source-interface" command to make sure the switch will source the Tacacs+ packets from the interface with the IP address for which you have the ACS configured to?

Given Below is the Error.. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Solution:
The error might occur due to following cases.
case 1: when the password is wrong
case 2: when you try to login from some App
case 3: when you try to login from the domain other than your time zone/domain/computer (This
is the case in most of scenarios when sending mail from code)
There is a solution for each
solution for case 1: Enter the correct password.
Recomended: solution for case 2: go to
security settings at the following link https://www.google.com/settings/security/lesssecureapps and
enable less secure apps . So that you will be able to login from all apps.
solution 1 for case 3: (This might be helpful) you need to review the activity. but reviewing the activity will not be helpful due to latest security
standards the link will not be useful. So try the below case.
solution 2 for case 3: If you have hosted your code somewhere on production server and if you have access to the production server, than take remote
desktop connection to the production server and try to login once from the browser of the production server. This will add exception for login to google and you will be allowed to login from code.
But what if you don't have access to the production server. try
the solution 3
solution 3 for case 3: You have to enable
login from other timezone / ip for your google account.
to do this follow the link https://g.co/allowaccess and
allow access by clicking the continue button.
And that's it. Here you go. Now you will be able to login from any of the computer and by any means of app to your google account.

Denying AAA Clients to a specific user group in ACS v4.1

Using 4.1 is there a "simple" method of simply denying a usergroup the ability to even login to specific AAA clients? Customer has a telephony group that they want to allow them to telnet and check into all the voice routers, but no other routers, they have the command sets and all that setup but wanted to see if a way to push that group simply to voice routers only ??
thanks in advance,
dave

Hi,
Why don't you use NAR (Network access restriction)
Under the network config > simply create one NDG and assign all the voice router under it.
After that go to the group/user where you want to put this restriction
You need to check that what are we getting in calling station id. If we are getting ip address then
[1] To accomplish above we would configure the group with following
NAR (network access restriction)
Define IP based Network Access Restriction
Permitted Calling Point
AAA client: VOICE NDG created
Port *
Src IP Address *
Subit the changes and try.
Here is more on configuring Network Access Restriction:

Hi,
Anything updates?
In addition, this issue may also because your client didn't have CA certificate of your domain. Please make sure that your client has CA certificate.
Besides, the error "The client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server" may be due to that the default maximum transmission unit that NPS uses for EAP payloads is 1500
bytes. You can lower the maximum size that NPS uses for EAP payloads by adjusting the Framed-MTU attribute in a network policy to a value no greater than 1344:
Configure the EAP Payload Size

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.

802.1x RADIUS authentication problem with Cat 2950 to CiscoSecure ACS 3.3

I wondered if anyone can help or shed any light on the following problem.
I am getting an authentication error when doing a RADIUS authentication to CiscoSecure ACS 3.3 running on a Windows 2003 server, the authentication request is coming from a Catalyst 2950 switch which is doing 802.1x for Windows XP clients. This problem only happens when the XP client connects to 2950 switches, Cat 3550s and 3560s work fine.
The Cat2950 is running 12.1.20 (EA1) which is more or less the latest IOS.
The error I get from ACS 3.3 is "Invalid message authenticator in EAP request" when the 2950 tries to authenticate an XP client for 802.1x to the ACS server using RADIUS.
Doing a RADIUS and 802.1x debug on the 2950 I see a message about 'Unknown EAP type', I am using PEAP on the XP client doing EAP-MS-CHAPv2 authentication, the same XP client authenticates fine with 3550 and 3560 switches problem only affects 2950s. Can anyone confirm the 2950 supports EAP-MS-CHAPv2?
I have checked and re-checked the shared secret and it definitely matches on 2950 and ACS.
One thing I noticed in the RADIUS debug is the 2950 sends 18 bytes for attribute 79 when the RFC defines attribute 79 should be 3 bytes or less, I don't know if this is related to the problem or is correct behaviour.

Hi, I am new with 802.1x, and was hoping that someone would help with these queries:
1. How is a certificate requested without being allowed on a network that is not authenticated with 802.1x. I had to first connect to an active network, retrieve a certificate with the proper username and password, and then physically connect to the port on the 2950 switch which was enabled to do 802.1x
2. My config is as below:
aaa new-model
aaa authentication dot1x default group radius
aaa authenication login default group radius
dot1x system-auth-control
interface f0/1
switchport mode access
dot1x port-control auto
end
I able to login using the radius server, so radius is working (on ports other than f1/0). However when connecting to f1/0, the port on the 2950 remains blocked.
3. The certificate is issued by the ca server, is viewable via Internet explorer,and is issued to the correct username which is on the active directory.
I even tried using local authenication with 802.1x, this did not work
4. If I have a certificate, will this automatically give me access to the 802.1x port?
5. I have windows 2000, and authenication is set to 'Smart Card or other certificate.
Am I missing anything?
Any advise will be greatly appreciated

13017 Received TACACS+ packet from unknown Network Device or AAA Client

I am adding new routers to our Corporate network for a new MPLS network. I am getting 13017 Received TACACS+ packet from unknown Network Device or AAA Client errors for these new routers. They are added to ACS 5.4.0.30 correctly just like all of our other devices. We have never had real routers on the network before, just switches and access points. Is there something special I need to set in ACS for these to work and authenticate correctly? I can only access the currently with built in login locally.

TACACS+ packet from unknown Network Device or AAA Client

Hi all,
I can't perform login using the credential set at ACS server, From the log it shown:
"Failure Reason: 13017 Received TACACS+ packet from unknown Network Device or AAA Client"
I know there's some changes on TACACS+ part for new catalyst IOS, so i refer the guide and this is my config snipet:
aaa group server tacacs+ TAC_PLUS
server name AUTH
tacacs server AUTH
address ipv4 10.10.21.251
key xxxxxx
aaa authentication login TAC_PLUS group tacacs+ local line
aaa authorization exec TAC_PLUS group tacacs+ none
aaa authorization commands 15 default if-authenticated
aaa accounting update periodic 1
aaa accounting exec TAC_PLUS start-stop group tacacs+
aaa accounting network TAC_PLUS start-stop group tacacs+
aaa accounting connection TAC_PLUS start-stop group tacacs+
My platform is
- C6500 running on IOS 12.2 (33) SXJ1
- ACS 5.2.0.26
Need guidance on this, thanks
Noel

Hello,
Is the appropriate IOS IP address defined on the Network Devices and AAA Clients for the ACS? If yes, which IP address is reported on the ACS Failure that includes the error "TACACS+ packet from unknown Network Device or AAA Client"? Is the ACS reporting the IP address as unknown when it is already defined appropriately?
Regards.
