Cisco AAA/Identity/Nac :: Restricting User Sessions In ACS 5.1?
Jul 26, 2011
We are using ACS 5.1 in our network. We have created users and grouped them as per the requirements. We want to restrict the user sessions in the network. A user should authenticate and able to access a network resource. But when he is active with that session, we need to block him from another successful authentication. We want to avoid multiple users using same user credentials for logging into the devices. whether this can be achieved by making configuration changes in ACS.

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.

we use an asa5520 like vpn termination point, asa uses acs5.3 for authentication purpose, and all seems to work properly,but acs5.3 doesn't purge user sessions when vpns terminate; I can see many user "logged-in" into menu System Administration --> Users --> Purge User Sessions; this is a problem, because we have configured max session per user how can avoid this problem? is there any new configuration to implement into asa?
we need to configure max session per user, but there is only a global option applyed to all users.how can we configure user accounting? we need to know how long a user is connected via vpn session.

I just started configuring AnyConnect with ASA 5520 that uses Cisco SecureACS to pass radius authentication. I configured two profiles with different split tunnel restrictions and what I discovered is that when the client connects to the ASA, they are provided a choice of these two groups (I guess there is no way to restrict this) and I can log into either one with any user account. How do I restrict this so that the user can only use one profile? Currently users capable of VPN would be placed in one specific AD group so that is what SecureACS checks. Is there a sample configuration guide to handle multiple profiles with different levels of access?

I have Configured a WLAN with WiSM2 Controller installed on a 6500 series, Aironet 3600series APs and ACS 5.3 for userauthentication. The ACS is connected to Active directory so users are authenticating using the AD (802.1x is used and not a pre-shared key) on SSID A. I have created a separate SSID B for guest users. I have put restrictions on this SSID. Guest users are also created on the same AD where internal users are created. How can I force Guest users to connect to SSID B and not be able to connect to SSID A? Currently they can connect to both.

I've looked at the forum posts and the document post, and I understand the explanations. My question is, under system administration>max user session global settings, would setting a timeout (say 1 hour) purge these sessions?
Under access policies, I am not enforcing max concurrent sessions per user, due to some of our devices using a generic log in. But if I understand the explanation, and my understanding might be wrong, then setting an expiry timeout should purge the accounting sessions, right?

We are using ACS 5.1 and from time to time we are getting a warning saying that the active sessions are over the limit (250000). It is just a warning, so my assumption is that its not a big deal, but how do we keep from getting the event, or prevent the event?

I have recently enabled the SMTP alert function in ACS 5.3. It seems to work well for most of the alerts. One thing though, the active sessions are over limit warning that comes up every so often. I know it is not impacting operations and it is ACS's way of clearing out sessions that had no accounting stop, but how do I disable this alert from being sent by e-mail from ACS 5.3?

I have ACS 5.1.I have created the Identity Group 'Admin' and added 2 users in that, say User1 and User2.How do I permit only User1 to get authenticated when he logins in to the device?There is option to select 'UserName' while creating Service Access Policy , but I have observed that though I have mentioned only User1 in the rule, User2 is also getting permitted

My company's security group uses Tripwire to monitor for changes in start-config and running-config on network devices in PCI scope. We are migrating from ACS v4.2 to v5.2. I need to create the account for Tripwire on the ACS Appliance but did not want to assign the admin role which would give access to configure terminal. The user role does not have privileges for show start-config or show running-config. Am I missing something or are these the only 2 roles available at the CLI? Can another rolle be added?

I want to have a local user in ACS that is permitted to login to routers. I have TACACS with AD already working but cannot get a local user to work. I used to do this in ACS 4.x.I created a user in the internal identity store.I tried configuring a policy to allow this users TACACS authentication multiple ways to no avail. I cannot find a config example doc and cannot figure it out from the user guide as the documention is sorely lacking.

So we have this problem that just started, I can replicate the issue as well, if a user makes a mistake on typing there password after 1 attempt ACS sends 3 to AD locking out the user.
In a putty or secureCRT session after 1 password failed attempt, I am unable to retry with that same session.
The issue seems to be that after 1 bad password attempt, from the client side I am unable to get another try.

We are using ACS 4.2.1.15 with patch 8 on ACS 1113 SE box.
Our requirement is to assign ACS loal group to user on basis of windows Nt group. Which means I dont wants to create individual users in ACS rather when user will login, the auth request will be forwarded to AD(remote database). Depeneding on the remote database group the user should be mapped to local database.
For this I have configured "database group mapping" according to following cisco guide. [URL]
However when ever my AD users are authenticating they are getting the membership of default group as configured in "Default" profile. I am using TACACS+ protocol in my routers and switches for authentication.
whether "Group mapping by External user database" works with TACACS+ or only with RADIUS protocol. If it works with TACACS+ what else configuration need to be done so that my ACS can map users to proper groups instead of default group.

I use ACS appliance 1120 for cisco devices administration. The identity store is external. I use Active directory. Actually, Authentication, authorization and accounting work well but users can not change theirs Active directory password when they have expired. Do you now how to configure ACS to permit password changing?

we have created some administration accounts which should only have the possibility to work on the user database. the useradmin role is to limited to create a user and set a fixed password only, but not able to enable the users authentication against a predefined external identity store. Other roles which makes this possible are far to powerful for a second level adminstrator.The adminstrator should have the possibility the create an user and set the password check against an external database. This is not possible with the predefine role "UserAdmin". Other roles do have to many rights for these users.

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?

A short background. Our corporate SSID is being migrated from using PEAPv0 to EAP-TLS. This restricts access only to company notebooks. Additionally we have barcode scanners which are used to inventory assets. Those devices are not able to use EAP-TLS as they cannot be integrated in the domain and being unable to do certificate based authentication.
As a workaround we planned to use another SSID with access to the same network but using PEAPv0 as authentication method, basically the same SSID but with a different name. As this naturally allows anyone to access the corporate network with a valid username/password I now wanted to add another step into the authentication process - the MAC of the device. I know I can do the filtering at the WLAN controller, but as it has a limited database as well as the fact that it is cumbersome to maintain the MAC list on all the controllers I thought I can do it over our ACS system.
I am now trying to accomplish the following: The user gets authenticated via the internal user store, which is succesful. Now I want to authorize the user via the MAC address, which is stored in the internal host store of the ACS, if access is granted or not.
For this I created the following policy:
Service Selection Policy -- (Rule based result selection)
-- (NDG:Device Type in All Device Types:Wireless And RADIUS-IETF:Called-Station-ID contains <SSID>) | Result: PEAP access
-- Default | Result: DenyAccess
Service PEAP access Identity: Internal Users -- (Single result selection) Authorization -- (Rule based result selection) -- Internal Hosts:HostIdentityGroup in All Groups:Valid_MACs
When I then try to access the wireless network I won't get authenticated. The error I get, when I look into the logs is: 15039 Selected Authorization Profile is DenyAccess
Is it not possible to use one identity store as "attribute database" for the other identity store?

I am trying to create a user restriction to allow one user to access only two networks (10.192.3.0 and 10.192.5.0) I have range of networks but I want to permit only two networks for limited user and full access for the admins. I know this was possible with ACS 3.3 but I am not too sure if this is also applicable with ACS 5.2.

I am using ISE 1.1.3.124.My first question:I want to know the relation between the attribute "WasMachineAuthenticated" and the MAR (MAchine access restriction in advanced setting for AD).Is-it the same or not ?Once you time out, you need to do machine auth again. What is the timer ?Using the attribute "WasMachineAuthenticated", is-it the same timer that you configure in MAR ? In a distributed environnement, is the information about machine previously authenticated replicated to all policy node ?Because, if a swicth has 2 radius-server, we are not sure that it will point everytime to the same server.

how I can assign a static IP to a user in ACS 5.2. I am able to do it in ACS 4.2, but I don't see the same options under 5.2. General idea is that users authenticate from our VPN appliance via RADIUS, and upon authentication, their static IP is passed back to the VPN device. I can attach an arbitrary field to my local users by going to System Administration -> Configuration -> Dictionaries -> Identity -> Internal Users, but how do I get that IP address passed back when the user is authenticated via Radius?

For our wireless, we enabled the machine authentication, but we want to bind the machine authentication and user authentication together which means they need to meet both requirements to access the wireless, how can we do this? Right now looks like as soon as the machine is authenticated, it can access the network, no user authentication needed.

I have configured under Administration password policies about password lenght, items to be putted as number, letters and so on.on the second tab is the password expire for users and I configured to expire after 90 days.
I even tried creating a new user and changing a password from an existing user using Apache TOMCAT WAR,I have checked CLOCK of ACS appliance and setted up NTP on our internal NTP servers
even I create a new user or I change the password via Admin GUI or I change the user password via Apache TOMCAT WAR, I have the user being disabled in a few of minutes, half an hour.,As last, with CISCO AnyConnect is possible to warn the user about the password being expireing and if so, the change could be driven via AnyConnect or is absolutely needed a User Hand Task on the Apache TOMCAT portal I setted up with the ACS WAR application?

Is there a way to configure a webpage where end users would go to change their passwords? I would not like to use the network devices themselves with the "change password at next logon" option.
I believe ACS 4.2 has such solution. Does 5.2 have it too?
