Cisco :: 802.1x Guest Function To Authenticate Users Against AD Via ACS 4.2
Dec 7, 2010
We have a customer with ACS 4.2 Appliances who currently uses the Layer 3 web-redirect guest function to authenticate users against AD via ACS and LDAP to the AD, its a mixture of un-managed Windows, Mac & linux clients.
They want to move to an 802.1x solution.
Now MS-CHAPv2 is proably the obvoius choice (maybe it isnt considering Linux and MAC clients ... comments???). However the only option to integrate with AD is LDAP i.e remote agents or an upgrade to 5.x is out of the question.

I am trying to connect using officeextend but couldn't . I have managed to connect the officeextend AP to the DMZ WLC however i cant get the users to authenticte to the ACS (although there is a rule to access the access on ports 1813 and 1812). Should the DMZ WLC need the ACS servers (i thought they wouldnt require as they are anchored back to the Internal WLC that the ACS server address
oon a side note, i have'nt created dhcp for hte officeedxtend users - will this cause an issue - (just deciding on to it on WLC or windows server)In-fact i cant even see myself authenticating on the ACS server

We have remote users that dial-in over ISDN to a Cisco 2911. We have configured AAA to pass the authentication off to a RADIUS server. Once successfully authenticated, the router permits the users to access a single web server. However, we need to do some testing in our test environment, but unfortunately we don't have an ISDN line to test with. We have created a little environment in our LAB using a 2911, a switch, a RADIUS server & web server. I was hoping that we could simply create a "user" VLAN off the back of the 2911 to simulate our remote users, and access the web site from the test usr PC's over the LAN. I was hoping that the 2911 would be able to intercept the connection and pass the authentication off to the RADIUS server (as it does with the PPP ISDN traffic). But I cannot find anyway to do this, because I can only configure AAA to offload either PPP traffic or telnet/ssh connections to the router itself.
In summary what I want is for a user to access an internal web site over a LAN interface of a 2911 - but have the 2911 authenticate the user via a remote RADIUS server first. Is there a way to configure a 2911 (or any router!) to do this?Is the answer to configure port-based authentication (802.1X) on the switch?

I have an issue with an implementation, I had a ACS R5.1 that I'm using to authenticate the wireless users with 802.1x, that's OK and working fine. Now I want to use the same ACS to authenticate wired users using MAB (for IP phones, printers, servers, and other devices) and 802.1x (for corporate users). I already configured the authentication services (MAB and 802.1x) on ACS, but when I'm doing tests I can see that for example the phones are trying to authenticate using the 802.1x rules of wireless connection, not using the MAB rules. [code]
You could also see an screen from the ACS in the attached file. On the picture remark you could see a IP Phone trying to authenticate using the wireless Access Services insted of using MAB.

Having an issue with Cisco ACS v5.1.0.44 and the Cisco WLC 5508. Cannot get users to authenticate and keep getting error messages referring to EAP session timeouts from WLC filling our logs. Seems to be with this model WLC because we have Cisco 4400 WLCs pointing to the same ACS with no issues. Is there a bug or special configuration that is necessary to marry the 5508 with ACS v5.1.0.44?

Is it possible for ACS 5.1 to only allow specific AD users to authenticate the switches and routers? Currently What I have configured is only for all AD users. I can't seem to find a way to be selective.

we are using ACS4.2 to authenticate wireless users for ssid : copr-wireless. the acs authenticate users via windows database (acs is a member of the windows doamin) no local user defined in acs. there is a mapping between all windows users and a local group in acs (wireless_group) in wireless group i defined the vlan as 80 so that corp-wireless clients will be in vlan 80 and they can take an ip address from one DHCP server in the network. vlan 80 is in our core switch. the dhcp also.
now we added a guest anchor WC with ssid: guest-wireless. we need to auth guests also via ACS/Windows. guests are the same users as corp-wireless but corp for lan only and guest for internet only my prob is that ACS will map guests to vlan 80 because they are member of the domain, however guest users should not have any vlan. it is like if they are in DMZ. they will take ip address from the anchor WC.

We are running Cisco Secure ACS for Windows version 4.1(1)b23p5 on a Windows 2000 member server. Starting from today, ACS fails to authenticate users. Using the same external user (andrea-meconi) I can verify successfull and failed authentication. This is the AUTH.log for a genericRADIUS request...

I am trying to configure a Cisco ASA 5505 so that users can authenticate via Radius or via a Local account using the Cisco AnyConnect client. In the AnyConnect Connection profile, the basic tab, it has Authentication Method. We have this going to an AAA server group with Use Local if Server Group fails option is checked.Each time, I see where the user has failed while attemtping to log in to the domain via the radius servers and thus bypasses the local user database all together.

The ACS can authenticate people using local database , it can also authenticate a single user (using windows database) if you are fast after the service is restarted , however after a few secounds, it fails to authenticate any users , the error we are seeing on the logs appear as authentication failure type : internal error. Also on the log files, the authentication request from the user does not appear in the correct group, it is thrown into the default group.

I have ACS 4 integrated with RSA 6.1, where users of ACS can authenticate their passwords with the rsa server.I am migrating users to ACS 5, and I want to integrate with rsa.
I am configuring rsa as “rsa secureID token servers”.But how should I configure the users on acs to authenticate the password with rsa?
Previously on acs 4, on the user page, in password field, I select authenticate with external DB, Also, any guide for the config on rsa 6.1 side (with acs 5)

I have successfully set up a windows 2008 box as a Radius server and use it to authenticate VPN users against ta AD database.I have also set up a similar policy that permits authentication for management purposes to all my networking devices (routers,switches and the ASA).Both policies work fine.Of course I don't want every VPN user to have administrative access to the ASA and every other device on my network.How can I discriminate between the 2 groups (VPN users and Network administrators)

I have a WLC 4404 with LWAPs, the customer has a microsoft LDAP and all users are joined to the domain and he wants the users to be authenticated against their domain accounts and this should be done automatically so that when users login to windows they are also authenticated and joined the WLAN.so how we can do that with the simplest way, without Radius server using only the LDAP and wwithout envolving any certificates.also i need to know when i add LDAP server to the WLC, how can i know that this LDAP is properly inegrated with the WLC?

Deployed two Cisco ISE 1.1.3. ISE will be used to authenticate wireless users, admin access to WLC and switches. Backend database is Microsoft AD running on Windows Server 2012. Existing Cisco ACS 4.2 still running and authenticating users. There are two Cisco WLCs version 7.2.111.3.Wireless users authenticates to AD through ACS 4.2 works. Admin access to WLC and switches to AD through ISE works. Wireless authentication using PEAP-MSCHAPv2 and admin access wtih PAP/ASCII.
Wireless users cannot authenticate to AD through ISE. The below is the error message "11051 RADIUS packet contains invalid state attribute" & "24444 Active Directory operation has failed because of an unspecified error in the ISE".Conducted a detailed test of AD from ISE. The test was successful and the output seems all right except for the below: [code]
Update:
1) Built another Cisco ISE 1.1.3 sever in another datacentre that uses the same domain but different domain controller. Thais domain controller is running Windows Server 2008. This works and authentication successful.
2) My colleague tested out in a lab environment of Cisco ISE 1.1.2 with Windows Server 2012. He got the same problem as described.

I have installed ACS 5.4 and we are looking to authenticate our Anyconnect users with ACS via Active Directory. I think I have the correct commands in our ASA ( we had ACS 4 and authenticated our anyconnect users ).
I also have configured ACS to use Active Directory and installed the server side cert in ACS. I'm just uncertain how to program ACS to use the security group that I have setup in Active Directory.

I am a restaurant owner and have a wireless network set-up via DLink DSL 2730U router. Now some times I get customers who demand to use the network and they use it for free which I find irritating. I have found one solution of 'Guests/Virtual Point' but I need to limit the time (say 15 minutes) for which they can use the network.

Our Guest access system seems to be having problems with DHCP. It seems to take a while to deliver an IP address making the client device show the "limited or no connectivity" message, which of course makes the users complain. On one occassion I have seen my own client eventually picking up an address even after the limited connectivity message appeared. On another I saw the debug showing "Dhcp request for autoconfig address", which I suspect is a symptom of the problem.
Our Anchor Controller is the DHCP server and is a 4402 running 7.0.98.0 - I've attached some DHCP packet debug.

I run a business and have customers who would like to use my wireless internet. I previously had a completely open network that I would allow them to use, until someone illegally downloaded a movie and got us in trouble. I would like to allow use of the network again, but limit activities like this. Basically, so they could only do basic web browsing, etc.

Have a WLC 5508 running 6.x code with LAP's providing wireless for our internal laptops (WPA2 and EAP-TLS). I want to provide guest wireless which goes out a different port on the WLC to a guest firewall/cable modem. However, we want to prevent our internal laptops from being able to use the guest wireless. I have RADIUS (IAS) and LDAP for my AD available. We would prefer not to have use Lobby Ambassador and just have the guests use a simple password or web passthru. Guests may be laptops or smartphones. What options are available? I have tried a test setup using dynamic vlan assignments from RADIUS using the IETF flags, but can't seem to get it to work. Is there a way to identify the SSID is being used at the RADIUS server?

My customer has multiple sites, each with a 2504 WLC.A data center with a 5508 in the DMZ acting as Anchor for the remote sites.ACS 5.x and NCS Prime.All guest users will egress to the internet via a Vlan in the DMZ.Authentication is currently web-auth on the Anchor, but will move to NCS once that is fully deployed.
Is it possible to put a printer in each site for Guest WLAN users to use?

This is the first time I am trying my hands on wireless gears. I have 2500 WLC and 1142 AP (which I converted from Standalone to LAP).I have a layer 3 POE switch where i am using port 1 for the WLC which is a trunk port.
Port 2 is for the AP using access vlan 111
Port 3 is trunk port going to a router where i am running dhcp server for the VLANs which are as follow:
VLAN 110 -Corp Wireless (10.1.110.0/24)
VLAN 111 - AP-Mgmt (10.1.111.0/24)
VLAN 999 - Guest (10.1.101.0/24)
I wanted to block the traffic from the Guest VLAN 999 but when i apply the ACL on the Guest Interface created on the WLC, I dont see any pings going across and neither I see any hit counts on the deny statement as if the ACL is never applied.

This PC has lost browser features because DNS has ceased to function. I can ping an external IP address, however DNS queries are met with the response "Ping request could not find host <URL>. Please check the name and try again." A VM on the same machine has no problem. Is there a root DNS utility on the host platform and a way to diagnose it.
