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.
View 3 RepliesI am using ISE 1.1.3.124.My first question:I want to know the relation between the attribute "WasMachineAuthenticated" and the MAR (MAchine access restriction in advanced setting for AD).Is-it the same or not ?Once you time out, you need to do machine auth again. What is the timer ?Using the attribute "WasMachineAuthenticated", is-it the same timer that you configure in MAR ? In a distributed environnement, is the information about machine previously authenticated replicated to all policy node ?Because, if a swicth has 2 radius-server, we are not sure that it will point everytime to the same server.

supplicant - W7 with cert
authenticator - Catalyst 2960 with IOS 15.0(1)SE2 /newest/
authentication server 2x - W2008/NPS like a RADIUS server
The problem is the end station that are still connected to the supplicant port /use a EAP-TLS/ after the reboot supplicant! All of them will be put into the Guest VLAN instead of static VLAN 34!
[The question]
What is wrong and how to configure/tune and what authenticator or authentication server to prevent after the reboot to observe a authentication timeouts? Of course the supplicant after 20 minutes /next EAPOL start farmet put into VLAN 34.

If any authenticated user uses protocol other than (http, https) within timeout period, that user #is deuthenticated

View 5 Replies View Relatedpicking up on old thread, but same issue: authentification failed because of a timeout
*previously*! i was able to auto connect fine on this home network via wifi.the line and box recently changed, same provider, and now i'm the only one who can't connect.the SSID changed, but i've done all the usual routines, deleting and re-adding manually, etc. but nothing so far...
i *don't* think this is a case of changing gear, but i don't know enough about internet/connection/configuration to fix this. yet!
NB: when i perform the reset on the box as instructed, using the provider's setup software - i am not the account holder - for the wifi, it shows connected very briefly in the animation, and then goes off again; this is the authentification/verification failing, i conclude.
so: with what is said above, i'm wondering if my antivir is to blame, or the windows firewall settings.or malwarebytes.i'm going to study the info i've got off my system, and looking at the router via the http routine, offline, as i now have to get off the internet(...); i'll get the infos together so i can post something useful.

my current setup: Windows XP machines authenticating wireless using 802.1X to a Cisco ACS 5.3 that redirects the request to Microsoft Active Directory. All the statements that I make below are what I have gathered from reading on forums, some of them might be incorrect.
In the ACS Under “External Identity Stores” and “Active Directory”, there is a check box called “Enable Machine Access Restrictions” if it is checked and the Aging time is set to 8 hours and a Windows XP machine authenticates using it’s Domain credentials it will gain access to the network but if that computer is not rebooted after the 8 hours is up, Windows XP will not send it machine credentials again, it will only send the user/pass of the user and will loose access to the network. The problem we have is that most of the users do not shutdown their computers when they go home, they hibernate the computers thus when they come back to the school the 8 hours aging time on the ACS has expired. The ACS expects to see the Windows XP machine send it’s domain credentials again but from every forum I have read on, Windows XP will not send it again until it get rebooted (FYI, Windows 7 will send the proper info, thus they work just fine). In the mean time I have changed the aging time to 8760 hours but this should only be temporary because it is a security risk to have the aging time set so high. Moving forward what are my options to make this work properly?
-Is there a way to fix Windows XP?
-Is there a recommendation on how to bypass this issue but still give us decent security?
-Is setting the aging time so high, a non security issue?
-I guess worst case scenario, the customer can try to educate all the students and staff to reboot their machines every morning?
We're having trouble trying to deploy 802.1x authentication on a brand new site.
Our primary and secondary ACS are located in Paris and the new site located in Toulouse, France. Both sites are connected through the WAN. Everytime a computer/user connects to this new site in Toulouse, ACS 5.2 sends a "5411 EAP session timeout" error message.
I'm trying to configure a timeout for network connection, but when it suppose to disconnect client, it's not working. Is it possible to do this??
Only works when the client is connecting and is denied if the time is not valid. But how could I do this if the client is already connected, enable re-authentication?
i am configuring a Cisco Secure ACS 1120 appliance running ACS 5.0.0.21 to handle RADIUS request from a Cisco WLC 5508 appliance running version 7.0.116.0.these devices have open communication on all ports - no firewalls or ACL'sthey have successful ping communication The following statements illustrate some but not all the debugging I have done to ensure each device functions as it should in isolation.Using a simple windows RADIUS server (radserv2.exe) instead of the Cisco ACS This works and the WLC gets RADIUS response from my makeshift serverUsing a simple windows EAP client to query the ACS using RADIUS protocol this works and the ACS processes the RADIUS request and sends a responsePlaced a wireshark client on the network to inspect timeout. Wireshark logs the packet from the WLC to the ACS using port 1812 but doesn't see any packet responses from the ACS At the moment I have the WLC accepting the association from the wireless client and sending the RADIUS (PEAP, EAP-FAST or EAP-TLS) request to the ACS, the WLC receives no response and generates a timeout message and disassociates from the client. note this is not a reject or similar message, the ACS simple does not even process the packet. i.e. there is absolutely nothing in the ACS logs to suggest it even received a radius packet from the WLC. In summary the WLC and the ACS successfully function independently but they do not communicate via radius.
View 3 Replies View RelatedOur company has installed ACS Version: 5.1.0.44.6 Internal Build ID: B.2347 with patches: 5-1-0-44-5, 5-1-0-44-6. The security policy of our company includes a password change every 3 months. Our programmers had written a script that allows us to do it. When testing revealed that the script does not work. This is due to the fact that it is not possible to enter the mode "acs-config". In determining the reasons it was found that to enter this mode there is a limit on sessions (6 sessions). When the number of connections becomes larger than 6 then the script does not work. The documentation says that the update is not active sessions is set with terminal session-timeout. In this case, the terminal session-timeout 30. But after 30 minutes of the session will remain active. It interferes with our script.
View 1 Replies View RelatedI 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.

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

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?
View 1 Replies View RelatedMy 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.
View 2 Replies View RelatedI 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)"

View 1 Replies View RelatedI 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.
View 2 Replies View RelatedWe 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?

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?
