Cisco AAA/Identity/Nac :: CSACS-1120 To Active Directory Without Success
Apr 18, 2011
I'm trying to join a band new CSACS-1120 to our active directory without success. The process in it self should be pretty straigh forward, but so far no luck.
I've configured the relevant info under "Users and Identity Stores > External Identity Stores > Active Directory.
Active Directory Domain Name: xxx.com
Username/Password : domain administrator account
When I test connection I get a info dialog "This machine is currently connected to domain xxx.com".After which I try to save changes which gives a reply ""This System Failure occurred: {0}. Your changes have not been saved. Click OK to return to the list page."
I've noticed that in the system log "show logging system tail" that I get a exception as soon as I enter the AD configuration page and subsequently every time I perform a action on that section.
Why the AD join keeps on failing and what the debug exception I'm getting means?

I have an ACS applicance that had a version 5.1 and i did an upgrade to 5.3 with latest patch.For some reason, the runtime process got stuck in (reinitializing and restarting) state.i did the recommended action to perform ACS stop and ACS start and even hard reset of the appliance, but it did not cut itThis process turned out to be a bug and it should have been fixed in version 5.3, but it has not i guess
i know that acs reset-config will solve the issue, but i have a problem here , the license file will be deleted as well with the config and i cannot find a way to export the license and then import it into the reseted config ACS hardware. Unfortunately, the license file is not saved anywhere in the company and i cannot affort to lose it.how to export the license from the applicance (CSACS-1120)?

We are using ACS 5.2 and we are trying to create a Microsoft Active Directory (AD) Identity Store. We have a user to be used in the Active Directory creation General page and we would like to know how the test communication / ACS to AD communication takes place.
Our user is a predefined user in AD and has admin rights, but the password expires every 60 days. Will this affect the communication between AD and ACS 5.2 at everytime the entered user's password expires?

I have installed ACS 5.2 and configured it to join the Company's Domain as an External database with Active directory 2008. I'm facing a problem that the user once authenticated using it's active directory account it's cached in the ACS and take a while for the ACS to clear this username. For example, if user TEST authenticates and then we removed this user from the AD and then tried again; it authenticates although this users is removed from the AD !!! same thing happens when we change the user group on the AD, it takes a while for the ACS to clear the old user attributes and get the new ones from the AD.
it there an aging time for this caching mechanism, or can i clear the dynamic users manually just like in ACS 4.X ?

I am receiving a RADIUS authentication failure stating user must change password; however, password has been changed in AD and is not requiring change password any longer on the AD side.
Is there a cache on the ACS that needs to be cleared? AD connection from ACS to domain is fine. All other accounts authenticate.
It appears that if a user lets their account expire is when this happens. Account has been reenabled in AD and password has been changed. Still will not authenticate via ACS.

I'm attempting to integrate an acs 5v into the domain through the gui. The connection will establish, and the status will read 'connected', just as it lists the domain I've submitted. However, I can't seem to find anything listed under the directory groups, and when I run a connection test, I simply get 'Global Catalogue port status error.' Eventually, I'd like to configure this as a radius server.

question 1. in the typical active directory environment and doing wireless/wired 802.1x authentication on endpoints, should ACS join as a domain computer?
question 2. for the endpoint (domain computer) join the domain, in this case is the endpoint will trust the ACS ( also domain computer) ?
question 3. what if there's a GPO policy to install the rootCA certificate toward the endpoints. In this case, ACS should issue the CSR and let the domain CA to signed as the identity certificate? Am i correct?

I am working with ACS 5.2 and using Radius authentication for vpn client.
The authentication method used is Active Directory in an Windows enviroment with multiple domains in the same forest.
My problem occurs when i change a user from one group to another in Active Directory. After that i receive the following message when try to connect:
15039 Selected Authorization Profile is DenyAccess
The message is because match the default policy. Another user in the same AD group works fine. All domain in the forest have trust relation each other. I am using universal groups to include users from all domain belongs this forest.

A customer uses Active Directory where some group names contain special characters (ç ~ '^). The Cisco ACS 5.2 is presenting the warnings: "Not all Active Directory user groups are retrieved successfully. One or more of thegroup's canonical name was not retrieved "(Category CSC Oacs_ Identity_ Stores_Diagnostics; code 24457).
What are the results of these warnings to the customer's network? Slow? Loss of access?

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.

I've successfully integrated ACS 5.3 with Active Directory for 802.1x implementation. Now i want to cache Active Directory users in ACS so that the user request from ACS does not go to AD every time.
After a certain time period the ACS database gets sync with AD.

I can add a ACS 5.1 to an Active Directory without using the administrator account, I have a domain administrator account by another name. I can use this account to include the ACS domain.
I have a account domain admin but when i try to add the ACS to AD have this message "can not resolve network address"
The DNS and network connectivity its OK

I have just recently purchased a 5505 Controller and 30 3502i AP's. On my main corporate WLAN, I would like to allow users to be able to authenticate via Active Directory username and password.I am also looking for as little client side set up as possible. From what I have researched, I will need to use some type of EAP method.
I have come across two methods that appear to be the top contenders.
EAP-FAST - The method seems to be a possibility but I see that it uses certificates. If I use this method, does it mean that I would have to import the certificates to each machine manually? Also, can I configure thsi to work with just the 5508 Controller and an AD Database server or do I need an intermediary like IAS or ACS?
PEAP/GTC - This method is also a possibility and I think that it does not require certificates. Does this also require an intermediary like ACS or IAS.

I need to change the username and password ACS uses to connect to AD. I do a "clear configuration" and reboot and am unable to join the ACS appliance back into my AD with a different username and password. I am able to rejoin the ACS machine to the domain using the original username and pass. how to clear all of the AD config off of the appliance and start fresh and use a new account to join AD?

customer provide quite large network with dot1x deployment - there is dual ACS5.3 servers for authentication Wired, VPN and WiFi access. Users (and computers) are mostly authenticated against Active Directory - there are several AD servers in the network.I found there is tens of cases every day with error message:24401 Could not establish connection with ACS Active Directory agent.This happens in random day and night time regardless on current authentication load. how to diagnose this more deeply? Or where to look for – is it problem with internal communication with AD Agent or is the problem in communication AD agent to AD servers? How is solved redundancy in case one AD server is not accessible – as there is no such setting in the AD connection configuration in ACS.

I know that our VPN users currently use Active Directory to authenticate their VPN sessions, so now I'm wondering if there is an easy way to configure my company's Cisco ASA 5510 to use either a Windows Server 2008 R2 Active Directory group (preferred method) or specific Active Directory users (less preferred) and authenticate them for management access (privilege level 15) using their Active Directory credentials. I do not want this to change the IP range used for ASDM/HTTPS/Telnet/SSH access (currently all local networks, no VPN), as those are settings that my company does not want changed.

I'm looking to implement ACS 5.2 using 802.1X, we have two seperate AD domains.A single switch will need to support both ADs, so if a machine in AD1 is connected, it will be authenticated to the ACS using AD1 and applied to VLAN1, while a machine that is in AD2 will be authenticated to AD2 and applied to VLAN 2.
I'm looking at machine authentication, not user authentication, so I assume that I will need to import two certs from each AD.

Im sure this has been asked before but a quick search has not yielded any exact results so here goes
I have anyconnect up and working great on for vpn users using local authentication. Im going over the white papers and seeing a lot of options for NT domain, LDAP, tacacs+ etc
we would like remote vpn users to autherticate using their windows domain password, but Im not sure which would be the easiest and quickest option to configure, and I cant find a guide for asdm setup for this topic that doesnt cause more questions than answers . The white papers Im finding are confusing since I am a rookie at this topic.
what is the easiest/quickest way to setup windows domain authentication via asdm?

I'm somewhat new to ACS and am trying to complete a migration from 4 to 5.3.Currently, I've got ACS joined to my (2003) domain, and it shows status connected (although the test connect fails). I have aaa working without issue for TACACS, but all RADIUS authentication is currently failing. Logs show the message below: "24401 could not establish connection with acs active directory agent"I'm not seeing anything telling in the logs on the domain controllers.

I am deploying ISE with WLC 7.4. I have two SSID(s) running in my network 1. Corporate & 2. Services. I have a domain setup lets say "AD.com" with 4 groups 1. Corporate, 2. Services, 3. Employees, 4. Contractors.Here is an example of the scenario that I want:
AD.com Group : Corporate's User : 1. C_USER1
2. C_USER2
3. C_USER3
4. C_USER4
5. C_USER5
[code]....
Now what I want to do is have 802.1x authentication on my Corporate SSID that will check in AD.com, ONLY AND in ONLY corporate group for authentication. That is only C_USER1 to C_USER5 are allowed to connect to it. Users from any other AD group shouldnt be authenticated on this SSID.The same for the services group & SSID.

we've configured an ACS 5.1 and integrated it with active directory Win2K3, we created two groups in the AD for managing network devices one for Administrators and the other for operators (read-only), so we configured a device admin policy and both groups work fine, but now we are facing a little problem any user who exists in the AD can login (user exec mode) in the network devices and we want to restric the login with the policy, but we just don't know how. Is there a way to get a user be authenticated against external group or internal acs but at user level, just like you can do it in the ACS 4.X?

installing the Cisco NAC agent through the Active Directory Group Policy. (Windows 2008 R2)Currently Cisco NAC CAS servers has been installed, configured and the switches are added. But the ports are not active. Currently users are not passing through the NAC. When the ports are active and the users trying to access the network, the browser will ask the users to install the Cisco NAC Agent.I need t by pass this by installing the Cisco NAC agent through the active directory Group Policy. How to install the Cisco NAC agent (4.9.1) to all the users in the Network (Windows XP / 7 )through Active Directory so that the users will not know that the Cisco NAC agent has been installed in their computers. By this way the users need not install the Cisco NAC agent through the Web browser and will just login their user name and password and get into the network.

I'm working on implementing a RADIUS authentication for wireless access with the following :
- PCs running Windows 7, protocol used is PEAP (without validating the server certificate to make it simple at first),
- AP 1252 configured to use a RADIUS server to authenticate (it's working good with an ACS server 4.2),
- ACS Server 5.1.0.44.5 running as VM connected to an AD domain and working good with VPN connections,
- AD domain running on Windows 2003 Server.
My ACS VM is working good since a couple of months for VPN (RADIUS) and administration (TACACS) remote access, both using Active Directory. Now, I'd like to use it to authenticate people connecting to a 1252 Cisco access point but I'm getting this error "24427 Access to Active Directory failed". I switched from PEAP to LEAP but this is the same.

Does the new UCS hardware change anything ?Can we bundle 2 NICs somehow to get interface redundancy ?If still not possible to configure that in ACS 5 itself:Can it enentually be done on the "hardware" level within the appliance firmware (UCS BIOS) ?(RHEL would provide NIC bonding,,, unfortunately its not accessable from ACS5 CLI)
