AAA/Identity/Nac :: Cisco ACS Can't Find / Authenticate Internal User On 3550 Switch
Apr 29, 2012
I'm doing some testing with ACS server on my windows box and I can't seem to get a barebone radius authentication to work with ACS internal users. I tested the same configuration with TACACS and it works fine, so there's something missing or misconfigured in my setup.
I have a cisco 3550 switch that I want users to login using their ACS username/password.
1. Try to authenticate user in external database1 (radius) 2. When external database1 returns FAIL (because of bad password) ACS5 should try to authenticate user in another external database2 (radius)
Our customer has the business needs to authenticate remote users against AD with empty password. I've seen ACS5.1 release note where mentioned about resolved issue: #CSCte72751 #ACS 5.1 drops authentication with empty password.
I tried to authenticate dial-in users through Tacacs and Radius against AD with empty password but without success. ACS points to wrong AD password. Is it possible to authneticate remote users with empty password?
Migrating from 4.2 to 5.2 acs and have noticed there is no expiration date per internal user added. We expire users at different times due to their time on site. Is there something that has to be added to get back this basic feature we had before?
I have an ACS 5.2 server integrated with Active directory . Now i need to create an internal user account to login to some radisu devices using internal user database .I have near about 600 users all are authenticating through AD .
Using a CSV file, I can not add user in the internal database of the ACS I have a permanent "error File Format Validation Failed" However the file I want to import is a really CSV file.
My ACS5.2 joined Windows 2003 Active Directory successfully. I created Support group with user1 in the internal store, also created Support-AD group with userad1 in the AD store. Identity Store Sequency is set Internal first, then AD. I can map Support-AD group to the local Support group without any problem.
Internal user gets authenticated and authorized OK. However, if the user is an AD user, the rule for AD users is not picked. So it goes to default.
I am looking for a way how to set the password-rules for individually for for some users or identity-groups.I just can find the global settings,Background of the requirement: We want to use password-aging for most admin-users, for some we dont want that pw expires.
I have a cisco nexus 7000 switch and a cisco ACS 5.2. I would like to setup the switch to be able to authenticate users with tacacs+ using RSA secureid tokens when they try to logon to the switch.
I am configuring TACACS Authentication on Cisco 3550 switch .It has Version 12.2(25)SEA IOS image. A strange thing is happening, whenver I am enabling AAA new-model on this switch, and then after enabling I see ruuning-config . It shows me this
* included here to hide the specific information I dint specified any RADIUS server , why it is showing me radius-server source-ports 1645-1646 after enabling AAA New-Model As soon as i give "no aaa new-model", this parameter also vanishes. I think this is the only reason I am not able to do tacacs authentication.
I have problem with Cisco ACS 4.0 "Windows" with core 4500 switch "cat4500-ENTSERVICESK9-M 12.2" the problem shows only on one device "x.x.x.x" the problem is " Authen failed-------badcred------External DB user invalid or bad password" i can see it in failed attempt. on the same side i can see in Passed Authentications for same record "Authen OK", i can login to the mentioned switch using my ACS credentials and not local database credentials
can debug this from ACS if not how can view the authentication records from core switch?
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.
We looking into options for using VPN to allow users to work from home at our company. We already run Windows Active Directory and have a Cisco RV042G router. We would like to set up a VPN that will authenicate user through AD. Is this possible with the RV042G?
having LMS 4.0.1 is it possible to authenticate user on a group base and assign different privilege to different groups?. The user's group are available in the LDAP server.Do I have to use a TACACS/RADIUS server between the Ciscoworks LMS and the LDAP repository?
We are running ACS 5.2 patch 6 and want to restrict access for users to be able to add devices to the system.For example, admin person in site A can only add devices into the site A group and cannot see/access other sites groups.
Having an issue with Macbook authentication. All Macbooks at this one site, on same switch, going to same RADIUS server, work except for one. Looking at logs it appears server and client never exchange certificates. Attached is log for failed Macbook authentication.
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.
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 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.
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.
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?
On an ASA5520 v7.2 I can only seem to authenticate to the console when using telnet and not ssh. I can connect using both methods, but just have trouble authenticating with ssh. Here are relevent lines related to the issue:
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 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 ?
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.
I'm having an issue with a cloned vm of our ACS. We are moving it to a different location. I was able to clone it and get it back on the network, but I can't authenticate to it from any of my switches. I do have an older version:5.2.0.26
I'm currently looking for a solution in order to restrict the modification of the host internal identity store (add or delete MAC host) per group. The default administrator roles does not include "per group restriction". Under the ACS I defined one group per department? My objective it to allow each department to access their ACS MAC database to add or delete MAC addresses as required.
How to restrict internal identity store per group?Do I need to create new roles? and how?I was not able to get an answer from the ACS ADMIN manual.
I finished the CCNA and CCNP classes last year but due to wife/school/excuse I did'nt have time to buckle down and study for the tests. So since time is flying buy and I got my new desk set up I figured I would set my lab up and get cracking.
On top I have a a Pix 506 and a 1900 switch. I need to find at least two more switches, hopefully 3550's or something close.Then I have 5 2600's with an assortment of cards, but I would like to replace most of them to either WIC 2T or HWIC 2FE's.
Not shown on the bottom are 2 2500's that will be configured as Frame Relay switches. I have a 3600 sitting on my bench in the shop and I was hoping to get something I could configure as a terminal server as well. I have GNS3 on my lab box and was planning on getting another network card and tying it into the hardware lab.
I am not sure what I am trying to do is possible, so I thought I would pose the question on here. In ACS 5.3, I would like to use an RSA server and AD to authenticate my network devices. So when I log into a router or switch I would enter my AD username, be prompted for my RSA token, then when I enable be prompted for my AD password, or visa versa. how to write an access policy to achive this?
Rather than maintaining local accounts is it possible to authenticate admins against AD? I'm talking about administrators of the ACS server itself to be clear.
