Cisco :: 1813 Can't Get Users To Authenticate To ACS
Feb 14, 2012
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?

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.

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.

End user has APs config with Radius server, working fine
-server 10.42.1.21 auth-port 1645 acct-port 1646
-server 10.36.1.46 auth-port 1645 acct-port 1646
In some weeks all APs will be migrated to WLC. My doubt is regarding the config in RADIUS Athentication Server port number field. There is only one option for adding.Which port number should I use? , When a new server is added always show 1812 port number; documentation states that is for authentication and 1813 for accounting.

We replaced a WLC2106 with a WLC2112 and the 2112 can't authenticate anything. Both WLCs have the exact same configuration on them. We are using a RADIUS server to do MAC authentication. Both WLCs have been set to use no delimiter in the MAC filtering.
When the 2106 is in place, we have no issues and all allowed devices can authenticate without issue. However, when the 2106 is removed and the 2112 is powered up, every single device fails authentication and is put on the exclusion list. When we check RADIUS, it tells us the devices fail because they are locked. We unlock the device's account, and 5 minutes later the 2112 has screwed something up and they are locked again.

I have been trying to set this up for like 4 hours. What a waste of time. This should be as easy as punching in the IP and password for the radius server. It isn't.I have a brand new SG-300-10. LATEST firmwawre, I just updated it about 5 minutes ago. 1.2.7.6 I think.This is what I have done so far in the GUI: (I have CLI access too if necessary)
Security > RADIUS and entered my radius IP/secret there.
Security > Access Management Profiles > Create new template called ALL that permits access to all applications. Set it as active also.
Security > Management Access Authentication > For HTTP and SSH
I put RADIUS first then Local second.My radius server works. As I type this message I am logging in via radius with OpenBSD/Centos even Fedora. (If OpenBSD can do it, these switches can do it.)But whenever I try to login with RADIUS credentials to my switch, I get no logs or any connectivity reports on my radius server? Is the switch even attempting to contact the server? The logs dont show anything regarding RADIUS. I am trying a reboot now, but I don't think that should be necessary.Is there a step I missed? When first looking at this I expected it to be done in 5 minutes. I have been on this for lik 4 hours. Isimply want to login to the administration console (web gui) using RADIUS credentials.

I think i've got everything set up to authenticate against AD for Tacacs+ device logins. When i check the logs, i see:"24408 User authentication against Active Directory failed since user has entered the wrong password". This leads me to believe that it is checking AD correctly, however if i enter the password correctly for the same AD user, there is no log at all...no pass, no fail.
If i look at the Tacacs debugs on the switch, i see the following:May 25 10:55:07.927 CDT: TAC+: ver=192 id=874699084 received AUTHEN status = ERRORMay 25 10:55:09.932 CDT: TAC+: send abort reason=Unknown
Obviously the switch is communicating to ACS, and ACS is passing info back to the switch. ACS also appears to be communicating effectively with AD since it knows when i put in an incorrect password for the specific user.

we have deployed L3 in-band scenario for wireless 2 years ago and the solution was working without any problem. we have upgrade wireless controller to 5508, since then, when users login to the first page and certified, and they want to browse to the internet, NAC redirects the web page and ask for authenticatin again, despite the users' devices are being shown as certified devices in the list.

I have setup Cisco Identity Service Engine (1.1.1) with Wireless LAN Controller (7.2.110)Everything is complete unless the URL redirect. My guest client can join the Guest SSID and also can authenticate to ISE.But after they success to authenticate with ISE, the URL in the browser doesn't change to the pre-configure. It still be something like [URL]. Anyway the content in the browser is changed to the URL that being configured such as url...How can I do with this situation cause everything is working fine but only the browser URL that is not change to the preconfigure one.

I am transitioning from RADIUS auth to local auth and i don't want to hassle everyone to change in one hit.If i can get auth requests to look in the WLC local net db first and if not found try RADIUS then this is what i am after! You can easily do it with web auth but doesnt seem so easy via WPA2 method.

Have set up a pair of ACS 5.3 servers and have set up device administration authentication be passed through to an RSA server via RADIUS. All works great.
What we want to do is go a step further and set the system up so that ACS Administrators also have to authenticate to the ACS system by RSA via RADIUS (the same as the Device Authentication we've set up) for ACS administration tasks.
Looking at the options available in the ACS Administration setup (administrator accounts etc) there doesn't seem to be an option to authenticate via another method apart from a local administrator account on the ACS.
Is it possible to do this?

I have seen couple of people with win7 cannot authenticate to ISE: 12520 EAP-TLS failed SSL/TLS handshake because the client rejected the ISE local-certificate.I've thought of this: Maybe get a 3rd party cert (go daddy) and have that installed in ISE.I know i do have to make a CSR Cert.Sign.Request that matches cn=primary.ise.mydomain, would I also need a cert for secondary?
If I use LEAP as a preferred protocol then it doesn't ask for cert and users are authenticated successfully.I know they have to say do not validate cert and all that but sometimes it doesn't popupt to them they just can't get on.Again maybe going wtih 3rd party certs will make it easier while benefiting from using PEAP?

I am trying to configure my ACS to allow 802.11 phones to authenticate. I have searched high and low for documentation on doing this with no luck. We are using unified wireless with a mix of 5508 and wism controllers.

The user "shreedhar" is getting authenticated locally and not through TACACS+ (Cisco ACS 1121 appliance running ACS 5.1).
In the switch, after entering credentials, the switch says, "Authentication failed - login using local mode". (Not the exact message but close enough!).
In ACS 5.1 -> Monitoring and Reports->Dashboard->My Favorite Reports->Authentications-TACACS+, I am getting the following error, "13011 Invalid TACACS+ request packet - possibly mismatched Shared Secrets".
Configuration in switch is as follows:
feature tacacs+
username admin password 5 $1$joEvYokP$5wZ1mtpBlxuoKMEWbFzRY1 role network-adminusername shreedhar password 5 $1$x8u5N4IR$NbVcY1u6CuoXYkMgXs60l/ role network-admin

Is #the encrypted TACACS+ shared secret key from switch not being decrypted by ACS 5.1 as it requires a clear-text password? Could it be the reason for the above error?

We are doing a new installation of a Cisco ACS 5.4 replacing a Microsoft NPS.
Recently I ran into issues with Lexmark wireless printers authenticating against the ACS 5.4.
While these printers work against the old Microsoft NPS we want to replace, I get "11500 Invalid or unexpected EAP payload received" on the ACS.
Windows/Android/iDevices authenticate against the same SSID using PEAP. I suspect, we ran into
CSCtq46211 Bug Details
Lexmark Printers work with ACS 4 but not ACS 5 Symptom: Lexmark printers uzed to work with ACS 4.2 but they produce "internal error" on acs 5.1 or 5.2
Conditions: Not known exactly
Workaround:1st Found-In 5.2(0.26.3)
Fixed-In 5.3(0.40.7)
setting up a new VM with ACS 5.3 patching it to P7, reconfiguring and retest all the stuff we implemented during several days ist not an option.
The Cisco TAC refuses to open a SR because the product is under warranty only, and claims warranty only covers HARDWARE replacement... (and we ordered ACS is a VM,,,) Maybe I should burn the ISO image to a DVD and RMA it for repair .
Maybe Cisco could verify whether the fix for CSCtq46211 has been integrated to ACS Version 5.4.0.46-B.221 already or not ?
