Two ACS 3.3 Appliances

Hi there
I was wondering what you can do with ACS replication between primary and secondary ACS. I want to install two ACS's together with PEAP in a wireless environment. I read on the site that external user database replication is not posible. I want to check the Active Directory for user authentication.
Do i need to configure the two ACS's seperately ?

Remco

Hi Remco,
In ACS 3.3 the following items cannot be replicated:
-IP pool definitions
-Cisco Secure ACS certificate and private key files.
-All external user database configurations, including NAC databases.
-Unknown user group mapping configuration.
-User-defined RADIUS dictionaries
-Settings on the ACS Service Management page in the System Configuration section.
-All logging configurations.
-RDBMS Synchronization settings.
Check the following doc about more details on ACS replication:

    Hi,
    Maximum number of appliances supported—While a single Cisco Secure ACS Remote Agent can provide services to many Cisco Secure ACS Appliances, support is limited to five concurrent connections by the appliances served. For example, if you have three appliances that are primary Cisco Secure ACSes and three appliances that are secondary Cisco Secure ACSes used for failover purposes only, the remote agent can provide services to all six appliances and stay below the maximum of five concurrent connections.

  • Unable to register a secondary ACS 5.2 appliance

    Hello,
         I have installed 2 ACS 5.2 appliances, the two appear as Primary. When I try to register one of them with the other one using "System Administrator -> Local Operation -> Deployment Operations" I get the following message:
    This System Failure occurred:  Unable to authenticate with node.. Your changes have not been saved.Click OK to return to the list page.
    I have tried with both "ACSAdmin" and "admin" users with their respective passwords.
    Am I doing anything wrong?
    Is there any LOG I can check to troubleshoot this?
    Thanks a lot!!!
    Regards,
    Julio

    I finally found the problem. I was using admin user (super user priviledges). I created another user with all permissions and it worked.
    Thanks a lot.

  • Two ACS Server failover

    hi all,
    we have a asa firewall,and we want to authentication login user by ACS server ,
    in order to eliminate single failure,we build two ACS server and make one as backup,we also use two protocol tacacs+ and RADIUS.
    I just want to know how long will take,if the active ACS server failed and the login is authenticated by standby ACS.
    I have no idea about any "keyword" to search,so please kindly help me,or could you provide a Doc , I will learn it by myself.
    think you very much.

    Generally in failover scenarios we create AAA server group on ASA. The security appliance contacts the first server in the group. If that server is unavailable, the security appliance contacts the next server in the group, if configured. If all servers in the group are unavailable, the security appliance tries the local database if you configured it as a fallback method (management authentication and authorization only). If you do not have a fallback method, the security appliance continues to try the AAA servers.
    To create a server group and add AAA servers to it, follow these steps:
    Step 1 For each AAA server group you need to create, follow these steps:
    a.] Identify the server group name and the protocol. To do so, enter the following command:
    hostname(config)# aaa-server server_group protocol radius
    For example, to use RADIUS to authenticate network access and TACACS+ to authenticate CLI access, you need to create at least two server groups, one for RADIUS servers and one for TACACS+ servers.
    You can have up to 15 single-mode server groups or 4 multi-mode server groups. Each server group can have up to 16 servers in single mode or up to 4 servers in multi-mode.
    When you enter a aaa-server protocol command, you enter group mode.
    b.] If you want to specify the maximum number of requests sent to a AAA server in the group before trying the next server, enter the following command:
    hostname(config-aaa-server-group)# max-failed-attempts number
    The number can be between 1 and 5. The default is 3.
    Also, the default timed out for a server is 5 seconds so if the first server in the group is not responding the ASA will take 5 seconds * 3 attempts = 15 seconds before it tries second server in the group.
    If all the servers in the group fail to respond, then the group is considered to be unresponsive, and the fallback method is tried that could be LOCAL database as well. The server group remains marked as unresponsive for a period of 10 minutes (by default) so that additional AAA requests within that period do not attempt to contact the server group, and the fallback method is used immediately. To change the unresponsive period from the default, see the reactivation-mode command in the following step.
    If you do not have a fallback method, the security appliance continues to retry the servers in the group.
    c.]  If you want to specify the method (reactivation policy) by which failed servers in a group are reactivated, enter the following command:
    hostname(config-aaa-server-group)# # reactivation-mode {depletion [deadtime minutes] | timed}
    Where the depletion keyword reactivates failed servers only after all of the servers in the group are inactive.
    The deadtime minutes argument specifies the amount of time in minutes, between 0 and 1440, that elapses between the disabling of the last server in the group and the subsequent re-enabling of all servers. The default is 10 minutes.
    The timed keyword reactivates failed servers after 30 seconds of down time.
    Hope this helps.
    Regards,
    Jatin

  • ACS 4.2 Appliance and Windows Agent

    Hi
    Wonder if any one has an idea on this?
    We have two ACS, 1 windows and 1 appliance.
    The appliance is the primary ACS.
    The other night all our wireless devices failed to authenticate.  We tracked this down to the Windows server with the ACS Agent on it for the appliance.
    The error was failed to bind to domain server down, which found an AD server ran out of memory.
    Becouse the wireless controllers could see the appliance still, it didn't fail over to the secondary.
    I was wondering is there a configuration where if it fails on one ACS it trys authenticate on the second ACS?
    Alternative is to replace the appliance with a windows box so no need to use the agent.
    Answers on a post card :-)
    Cheers
    Craig

    Hi Craig,
    Unfortunately, the authentication request will not fall on fallback if the primary is still up.
    Hope this helps.

    Anisha

  • EAP-TLS + CA MICROSOFT + ACS 3.2 APPLIANCE = Problem

    I have a Wireless Lan platform composed by equipment Access Points Cisco 1100 with ACS 3,1 and CA Microsoft.The security scheme is EAP-TLS (certificates).This architecture was completely functional. The problem took place when replacing the ACS 3,1 by the ACS 3,2 APPLIANCE, for which new certificates they were emitted by the CA of the infrastructure. The problem appears when a wireless client tries to connect to the wireless network,without obtaining the objective ,being in a state of "trying to authenticate" in networks adapters, in addition the ACS Logs appear the following message "NAS duplicated authentication attempt".
    If somebody knows the reason of this problem, can be contacted to my mail ([email protected]).

    A hint i could give you that in such a scenario you need an Trusted boundary between the ACS Appliance and the MS AD/PDC. This we be realized trough an PC/Host who is a regitered member or user of the AD/PDC. This relay Computer then communicates with the MS CA. The SW that Cisco Provides is the Cisco Secure ACS Agent. Hope this helps as we found the same problem in leap authentication as the ACS Appliance could not be set into a AD/PDC Domain. This has to be realized trough this smal piece of SW installed on an PC/Host etc. wich is a active AD/PDC Member.

  • ACS v4.0 - Appliance vs. Server

    With the appliance coming into line with the server version of the ACS, what are the advantages of one over the other? I know the advantage to the engine is security hardened device. This doesn't matter to me. I want to know the advantages you have found and or the bugs you've found in one or the other.

    I would 2nd that... and I used to work in ACS dev.
    Appliances are great for simple things. ACS is primarily application software with a complicated set of interfaces that were not designed with appliancing in mind.
    When (if?) Cisco ever get around to re-architecting ACS then it may be different story.

  • ACS 5.2 appliance cli access

    Hi~
    Could you please tell me how can I make user access for CLI (shell) on ACS appliance by means of WEB GUI. The point is that I have ACSAdmin as well as another administrator role users, but can't get access to appliance through SSH (Permission denied (publickey,password,keyboard-interactive).). I need to troubleshoot RADIUS requests from my APC Networc Management Cards, by means of some sort of tcpdump, becouse I dont get any logs in ACS from APC cards.

    then either you need to enable more detailed logging on the ACS applicance
    How can I do this?
    or the RADIUS requests from the APC cards aren't reaching the ACS applicance
    This is what I'm trying to find out.
    Are there any firewalls, etc between the two devices that might be blocking RADIUS packets?
    No man, there is a clear IP connectivity between, but problem is that I can't troubleshoot RADIUS requests/replies on this part of transmission nor from APC side neither from ACS. I check all possible log records in "Monitoring and Reports" tab, but didn't find any request from APC devices.
    Also, if you have any configuration examples for APC (APC9630) devices RADIUS authentication by ACS 5.2 will be appreciated for the information. I have followed this  howto to configure VSA and apply policy, but still it doesn't work. I just want to verify are the RADIUS requests reach ACS or not.
    Thank you.

  • Passed Authentication Logs on ACS 4113 SE appliance

    I need to get a copy of all Passed Authentication logs from our appliance. Is there a way that I can ftp all those files to another device? Or is there another way that I can retrieve those files?
    Thanks
    Dwane

    Dwane,
    Yes, you can send logs to another system on the network using remote agent.
    Remote Logging for ACS SE with ACS Remote Agents
    The Remote Logging feature enables ACS to send data to one or more ACS Remote Agents. The remote agent runs on a computer on your network. It writes the data that ACS sends to it into CSV files. You can configure many ACS Solution Engines to point to a single remote agent, thus making the computer that runs the remote agent a central logging server.
    For more information about installing and configuring an ACS Remote Agent, see Installation and Configuration Guide for Cisco Secure ACS Remote Agents Release 4.1

  • ACS 4.2 Appliance integration with LDAP

    Hi,
    I would like to ask some question from the expert here.
    1. I'm building 802.1x infra for my customer.
    2. We are using ACS SE version 4.2
    3. We have successfully integrate the ACS with AD using Remote Agent.
    4. Using will authenticate using PEAP MS-CHAP v2.
    5. However, my customer dont want to use Remote Agent (RA) because the want the ACS talk to the external database directly.
    6. Their argument is, if they bought other Radius appliance for this project, the appliance should have the same function in order to authenticate the user.
    7. What are needed to complete this requirement?
    I saw in this table http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/Overvw.html#wp857274 the LDAP does not support PEAP MS-Chap v2.
    Can any expert give opinion on this issue?

    Despite various efforts a few years back, LDAP vendors could not be persuaded to implement an MSCHAP interface - which is technically possible.
    That said ACS also has its Windows External Authenticator that will do MSCHAP just fine to a Windows AD Server (via a different interface).
    The old LEAP protocol was mschap inside EAP. EAP-FAST can also do mschap too.
    The key is not use the LDAP authenticator in ACS. If you really must use it, you'll have to make sure you use EAP-GTC inside your PEAP/FAST tunnel

  • ACS 4.1 Appliance

    I cant ping my ACS but i can access it through the web browser this prevents me from setting up a connection between the appliance and my ftp server for backups. When i console to the device and attempt to do backups manually i get an error message saying that it could not establish connection with the FTP server. I can ping any device on my network from the Appliance but not the other way..any suggestions on how to do backups for the appliance.

    I can access my appliance both through the web browser and the CLI,the only thing im having a problem with is the connection between the appliance and my FTP server,it keeps giving me an error about not being able to resolve a IP or Hostname,I've specified a DNS server on the device and when im on the CLI i can ping devices using both their hostnames and IP's,when i do backups from the CLI they go to the CSUtils folder on the program files and i cant event access this folder on the appliance.

  • ACS 3.3 Appliance Remote Agents

    Hi,
    Can I configure Cisco ACS Appliance 3.3 to send logs to different remote agents which are not Cisco, for example Envision appliance.
    Regards,
    Ejaz

    No, because the protocol used between ACS and the RA is proprietary.
