Cisco :: Active Directory Authentication Failing?
Feb 16, 2012
I am not sure why but when I try to connect with my IPSEC VPN client, authentications are failing. The ldap test passes on the ASA but when I try to login, the VPN client gives me authentication failure even though debugs show authentication was successful.User 'test1' should be able to authenticate based on group membership.User 'test2' shouldn't be able to.I already removed the attribute-map to see if that was the problem but I am still failing authentication.

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 need to configure EAP-FAST without certificate and authenticate to the corporate Microsoft AD database, Do I need a Cisco ACS server in the middle to forward the authentication to the AD? Or I can do the authentication to the AD directly? I am using a WLC5508.

I current have a network setup with five 1240AG access points. One is configured as a WDS. I also have a WLSE appliance. I have IAS configured on a domain controller running Cisco Secure ACS Agent. My setup works and my clients can authenticate with certificates to Active Directory. My problem is that I need to take my WLSE out of the mix - it is old and failing. I cannot afford a replacement. I know that in order to use WDS, I have to have a WLSE.
So my question is this. If I configure my APs so that do not participate in SWAN, and leave them setup to use EAP and point to my Windows IAS for RADIUS, running Cisco Secure Agent, will they be able to authenticate still.
To be honest, I set this up a long time ago and I cannot remember if the WLSE is required for domain authentication. I know if offered Domain Authentication and I have my Windows Server setup in there. So I am not sure if my APs can authenticate directly to the Windows Server without it.

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.

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 trying to set up a small domain for my business. I just purchased a Windows 2008 server and would like to use it as my domain controller.Also, I just had a new ATT DSL line put in. It came with a 2Wire modem/4-port router/wireless router device, therefore the modem can handle DHCP. The line has a static IP address as well so that I can eventually use my own exchange server and web server.I have tried 2 different configurations and couldn't get either to work) I tried to put the router into Bridged Mode and use DHCP server on my server using a PPPoe connection to connect to the Internet. I was confused as to what my static IP address and default gateway of my server should be.2) Then I tried to turn DHCP server off on the server and routing back on the modem/router. This didn't work either.What method would you recommend and why? Also I have some additional questions on each method.
Method 1)
* What is the static IP address of the server. Is it in the 192.168.1.x address or the static IP assigned to my account?
* Do I need a second Nic Card And Router to connect to the rest of my network or can I use the router provide
* What would the Static IP addresses of the additional PC be. Do I need more than 1 static IP from AT&T Method 2)
* Will this allow me to use all internal IP addresses on my machines and use port forwarding if I want a specific box to be a web server or exchange server.

I know that when you create a user account in active directory, the user's computer is also added to active directory. However, in what circumstance would you add a computer to active directory in which there are no user accounts created, or used ?For instance, my Linksys wrt54g router, on the main configuration tab has a space to name the router, which is appropriate called, "Linksys", and it has space to enter it's domain name, which if I named it, I guess it would be. LinksysRouter.**.local.Why add a router to an active directory domain ?Why add any other computer to an active directory domain with no users associated with it ?

I've got this problem with our Operations Manager's laptop not letting him log in once he is offsite(at home). We use an Active Directory server here for all out workstations to log on to the domain but once he is offsite he cannot log in because the laptop obviously cannot find the sever to authorize the user. For now I just have him logging in locally to his laptop and not to the domain when he is offsite but this creates a problem; it makes two users/desktops for him, one user.domain and user.local. Is there a way to tell the machine locally that his username is authorized to let him log onto the domain account though it cannot connect to the domain server?

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?

I have installed 4 unit Cisco Aironet 1250 acting as Autonomous AP each. I want to integrate these AP to Windows Active Directory for authentication level.
When I read configuration guide on Cisco Aironet, they must be authenticated via RADIUS server.
Is it possible that these AP directly authenticated to Active Directory via LDAP protocol?

Currently We have several Active Directory Domain at several Technical High Schools. These are used by us as a it educational unit(s). The Tech School System's IT Department has a fiber wan between the schools that allows communication between these units. We wanted to interconnect the unit's Active Directory's with Trusts or by combining them into one forest. However I am wondering How much bandwidth that alone would require? There make be some file access between units but not on a daily basis since the units are separate from one another. How much bandwidth do you think this would require?

I have been rolling out new IP Phones that use extension mobility and the biggest issue Im finding is the need to log-in every day, People t like change and they hate the fact that they have to login every day.I have been to the people at the top and gave them the options of remembering the last user logged so users just need to enter their pin or have EM not log users out at all… both got rejected.

I have a 5515 ASA that has the webVPN configured on it and it is using active directory to authenticate. The client would like to set up groups in active directory and restrict access to those groups when they are connected to the webVPN. For example, they have a group in active directory that they only want to access their "web" interface. What is the best way to configure this on the asa?

I have a WAP4410n which I'd like to authenticate users against our corporate active directory. I would like to know how to achieve this - whether we require a dedicated RADIUS server, whether AD has a RADIUS engine which can be used, etc. Also, what would the pros / cons be of this setup versus using a WPA2 password?

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 need to give access only to their respective Group policy in ASA. Following are the available groups and GP.

After a certain time period the ACS database gets sync with AD.
