Oct 26, 2011
authenticate phone Mitel in ACS 5.2. I tried to authenticate a PC wich is behind of phone Mitel, but it doesn´t working.the solution work fine with vlan mapping.
This configuratión work fine with Phone Cisco but not for phone Mitel, and I had used this templace by both.
vlan 709 = guest
vlan 10 = voice
inter fas 1/0/8
switchport access vlan 709
switchport mode access
switchport voice vlan 10

I am piloting an 802.1x implementation for a client who has Mitel IP Phones. I have setup the switch and ACS based on previous experience and a windows PC can authenticate onto the network OK. When I use a Mitel phone however, it seems to skip past the first 802.1x LCD message and goes straight to LLDP and DHCP discovery, which obviously fails. The phone are 5224s and the controller is on the original v10 release. I have cleared the 802.1x config on the phone and rebooting as per Mitel documentation which leads me to believe it should then prompt for a user/pass on next reboot. It does not do this.
I known the ACS is setup to support EAP-MD5 and I have tried all the various types of host modes including the default and Multi-Auth, Multi-Domain and none of them seem to make any difference. I have tried with and without a PC attached to the phone as well.
A wireshark shows the EAP identity request from the switch, and I see an EAP response from the phone, although it is slightly different to the PC's response. In the end the phone issues an EAP 4 failure message. So something in that EAP conversation doesnt seem to work.

I configured before ACS v4.2 to authenticate network devices using internal users at first, and if the user is not found use AD list users. But with v5.3 I have some problems doing this, on identity policies I use rule based result selection option, I configured 2 polices for Identity source, one for Internal Users and other policy for AD user, but it only works with the first policy, internal users or AD, but works only for the first policy identity. how to do that, if the user is not found on first policy, continue to the next policy.

I need a specify users to allow access to particular devices and give privilege only for show command or show run. Here is how I tried to configured.
1. Configured two seperate Shell Profile and Command set with privilege level 4-5 and allowing only show run command
2. create seperate service selection rule with adding the require NDG and protocol TACACS and maching service "RestrictAccess"
3. In the RestrictAccess Service I have following configured; Identity: internal users, Group Mapping to a particular group where the user exists, authorization: matching the above created identity group, NDG, shell profile, command sets
All the steps are attached in the .doc file. However when I tried with the particular user he is able to access everything and he is not hitting the correct access rule.

Is it possible to set up a multi use port that will use dot1x to authenticate several laptops, only 1 connected at a time, but I need the phone to automatically connect without having to make changes to the phone config as I don't have access to the Cisco call manager to set up the authentication.
Setup would be using catalyst 3650x at the access layer, various Cisco ip phones models and a Cisco acs 4.2 server doing the authentication. The laptops would be plugged in through the phone. The switch is already in use and setup and using both data and voice vlans, but now I need to enable it for several users. The acs is already setup to authenticate our wireless network so I'm planning on using the same setup for the wired side.

I have deployed the NAC Solution. NAC Software version = 4.8.2 and Agent version = 4.8.3.1.The solution is working fine but the Cisco IP Phone CP9951 is getting restart after applying NAC (or port profiles) at some time interval. Time is not fixed but it doesn't seem stable. Sometimes, it is just disconnected while using the Phone and sometimes when you log-off or restart the PC.The Cisco IP Phone CP8945 is working fine in all cases.We are getting the message of "Phone not registered" and active call is getting disconnected.

In order to restrict access to websites on our internal network, would we be able to put an ASA in front of the web server and force users to authenticate through the ASA and, once authenticated, allow only port 80 or 443 traffic for that use? The ASA would query the ACS 5.1 server for authentication/authorization using AD as the identity store. Is this even possible with TACACS?

My customer has a large installed base of MACs, all connected via controller-based (5508) WLAN. He wants to grant access to the network based on the device's mac addresses and move the WLAN-clients to a specific VLAN.I added all devices with their mac addresses to the ACS internal identity store for hosts.According to the following message the client sends the user-login credentials (chegger) within the RADIUS-request instead of the clients mac address and of course it has to fail. After many configuration changes, I ended up always with the same result.

I have question on EAP-TLS with ACS 5.2. If I would like to implement the EAP-TLS with Microsoft CA, how will the machine and user authentication take place? Understand that the cert are required on both client and server end, but is this certificate ties to the machine or ties to individual user?
If ties to user, and I have a shared PC which login by few users, is that mean every user account will have their own certificates?
And every individual user will have to manually get the cert from CA? is there any other method as my environment has more than 3000 PCs.
And also if it ties to user, all user can get their cert from CA with their AD login name and password, if they bring in their own device and try to get the cert from CA, they will be able to successfully install the cert into their device right?

I have a new ACS 5.3 installation which I have joined to our AD Domain and added the directory groups into. I have also added all our devices into ACS and their groups etc but I am still only able to authenticate on the our switches with an internal ACS account, when I try with an external AD account the log shows the following error "Subject not found in the applicable identity Store (s)"

We got recently a Cisco Secure ACS 1120 and i upgraded the Appliance to 5.1 from 5.0 with all your support
Now I need to integrate Cisco ACS 5.1 with RSA Authentication Manager 6.1 . I Successfully Downloaded config file from RSA ACE Server and exported into ACS 1120.
I also Added ACS as a NetOS Agent in the RSA Server , during the process i found few warnings . The ACE Server is not able to Resolve the IP Address to NAme ( DOes it Necessary ?? ).
I havent created any secret Key file for communication between ACS and RSA and encryption i used is DES.
Now when I log into ACS and search for Devices in the Identity Store Sequences i am not able to Look for RSA Token Sever .

I have a Cisco ASA (8.2) setup with remote access for my users using Cisco VPN client. The authentication is passed off to my ACS 5.3 which then checks with AD. What I've done so far is create Access Policy rule where I define specifically the Location and NDG where the ASA is and then a DenyAllCommands command set. This should pass authentications just fine but this also gives those users the ability to remote connect directly into the ASA and login successfully. Even though there is a Deny Commands there I still would prefer they get Access Denied as a message. If I do a Deny Access on the ShellProfile then this stops the login authentication altogether.

We would like to enable ACS authentication to login to different routers (Cisco 881s) we got that are interconnecting with our WAN via VPN tunnels. We would like to avoid using public IP for the router to communicate and relay user/password info with the ACS server and rely on the server's private IP instead. The problem is that all the router's outside interfaces connect to the Internet using public IPs and when the router wants to communicate with the ACS server it will use its public-facing interface IP and that'll fail. We can ping the server obviously when we set the source to the internal LAN IP.
The question is is there a way to have the router communicate with ACS across the VPN tunnel using its private IP?
config being used and tested succesfully on local devices:
aaa new-model

i am evaluating ACS 5.3 with an ASA5505, by using password management in the IPSec tunnel config i am able to authenticate the VPN clients using mschapv2, however, the SSH sessions are authenticated using PAP
I have looked for days and days for an answer without success, is this by design?
Cisco documents state that SSH can be authenticated via TACACS with PAP,CHAP or MSCHAPv1, however, It seems to be default to PAP
From Cisco Doc: TACACS+ Server Support # The security appliance supports TACACS+ authentication with ASCII, PAP, CHAP, and MS-CHAPv1

I am getting ready to install a new ACS 5.1 server to replace my current 4.1 acs box. I wanted to start off with a fresh install rather than upgrading all of my 4.1 data.
Can I have devices (ASA for VPN authentication, routers & switches for user authentication) use both for authentication while I get all the users configured in the new box?

I have a questión about radius authenticaction with AD, when I log in into the network with user in AD and I make a mistake in password my radius authenticaction event in ACS 5.2 dont show me this logg. only show the authentication succeeded but dont show me the authentication failed. Maybe i must to enable same service to show the authentiaction failed. The Voice authetication works fine..
This is the confg in the port of the switch:

I configured ACS 5.3 and added AAA clients with TACACS+ server and shared secret key as cisco123. i did the below config on switch also. when i try to authenticate login with ACS it does not respond. Find the configuration and debug output.nd
In debug output it gives ruser and rem_addr is null. i did not understand why .
I am able to ping to ACS server and i used telnet 192.x.x.10 49 and it gives the proper output.

I have several devices on the same subnet and with similar configuration. All of them were entered manually on the ACS server and are configured to authenticate using TACACS+. Some of the devices can authenticate ok, but other will timeout. I did a tcpdump on the firewall port and can see the device sending the SYN to the ACS server but the server sends no reply to the device.

I am using Cisco ACS 5.1. I would like to authenticate my ip phones with mab (Avaya phones) and the commputers with dot1x.Everything works fine except that the phones which are successfully authenticated with mab tries to authenticate again and again and again ... and this fills up the ACS logs. Every authentication is successfull and the phone does not hang up. But this fills up my logs and makes them unusefull.

I configured WiFi connection on Windows XP and Windows 7 with EAP-TLS (using Cisco WLC 7.0.235.3 and Cisco ACS 5.2.0.26.10). It is configured with computer authentication and computers certificates are autoenrolled from Microsoft PKI.It works well!
Now I configured Windows 8 with same configuration.First authentication works but if I manually disconnect and reconnect, I got this error on ACS: 22047 Principal username attribute is missing in client certificate.In EAP packets, we could see that Windows 8 sent a TLS session ticket but session was not resumed correctly by ACS..On ACS configuration, we checked this option "Enable EAP-TLS Session Resume" with session timeout "7200".

I want to integrate my ACS 5.1 with AD, My request is to check for the machine authentication first. If the machine authentication passes the client username/password should be validated and client should be put in vlan X . If the machine authentication fails, the client username/password should be validated. If the authentication passes the client should be put in vlan Y.

I am having a problem getting an ASA running 8.3 to authenticate an SSL VPN directly against an LDAP on Windows Server 2003. I have changed the read access on the Active Directory to allow Annonymous to read it. I think I am missing something on the ASA config. I have the Server Group specified with the address of the correct server but nothing else really configured.

I tried to configure TACACS+ authentication / authorization for NCS via ACS 4.2. For that I followed the configuration guide:
1. Configured the service for NCS with HTTP (see attachment)
2. Added the tasks to the user (see attachment)
When I try to login on the NCS it fails, in the logs on the NCS I see the following lines:
