Cisco ACS secure 5.3 allowing foreigners on ACS local domain server domain accounts

All the

My company has recently acquired another company

Each company has its own domain and controllers

The problem:

Executives of the absorbed company sometimes come to the main site for meetings using their own laptops

configured for their own areas. This caused problems of authentication wireless with Windows 7 machines.

The domain account when you connect is forcing the dispatch of the password, the name of domain user and the foreign domain

The need:
We need to somehow add foreign domain as the source of authentication on the local ACS authentication attempt with our wireless controllers is allowed.

Give advice on how this could be achieved.

Hello Steve,.

Concerning the behavior that you experience with ACS to be able to authenticate users against the foreign domain is completely expected and you will only be able to authenticate by entering the user name and domain name.

The only option to join the ACS for a foreign domain is LDAP configuration and in this way, you will be able to join the AEC directly with this area, however, there are several limitations on the supported protocols when you use LDAP as you can see from the following link, then you want to see if he would be available as an option for you or not depending on the Protocol that you use (which I suppose is it PEAP / MSchapv2) as you mentioned that users will type the identifying information, so it does it does not for you):

    Hi all

    We recently deployed device Cisco ACS 3495 and running on a version 5.8.

    Once fixed, you can increase the car locked out amounted to something greater than the default value of Cisco.

  • Cisco ACS Local certificate

    Hello

    I'm working on GBA version 5.6 and I would add a second certificate for EAP protocol in local certificate.

    I don't know if I can without deleting the first.

    Could you please help me.

    Best regards

    Unfortunately you can only have 1 a certificate coupled with the EAP protocol. That being said, you don't have to delete the original certificate. You can add the second certificate and allow with EAP. This will automatically remove the binding of the EAP to the first certificate. But in the end, only a single certificate can be bound to the EAP protocol.

    I hope this helps!

  • Cisco ACS server

    Hello

    I currently have a Cisco ACS 3.3 Server. I want to upgrade the server to the latest version and cluster with one another so that we can have a redundant infrastructure because if one fails it also includes...

    Can provide you a solution for this?

    Thank you

    Hello

    The latest version is 4.1 ACS. You can upgrade 3.3.3 build 11 directly to 4.1.

    Then, you can install an another ACS 4.1 on a different machine and replication configuration between these two. In this way, you will need to make changes to only one that ACS and the secondary will be automatically updated.

    Once these two are defined, you can set both of these servers as a server Radius/Ganymede on devices and there will be a redundancy.

  • 5.4 double certificate option Cisco ACS

    Hello Experts

    I wonder if anyone knows if I can get two certificates on my Cisco ACS 5.4 server. The documentation says I can have it as long they have different 'from' and 'to' dates with a same name CN. However, this is a production server and wanted to if sure before I make changes. I currently have a certificate installed and everything works well but need to add a second for migration purposes.

    Hovsep Armeni
    LAN, UK

    A certificate can be linked to these two services (HTTP and EAP), however, each service can only be associated with a single certificate. Thus, for example, you cannot have two certificates that are related to the EAP process.

  • Cisco Security Manager integration with Cisco ACS troubleshooting

    Hi all!

    I have a problem with the integration between Cisco Security Manager and ACS. I've done the integration, but the identity of the user system doesn't have enough privileges. I know what the problem is, but I don't know how I can change the login of the ACS to the local MSC?

    I found a file that specifies the following:

    Q.

    Is there a backend script or command line interface options to change the ACS to local CicsoWorks connection module?

    A.

    To restore the server LMS ACS local user mode mode, stop the CiscoWorks

    demons and run the following script:

    NMSROOT/bin/perl ResetLoginModule.pl

    (for Solaris)

    NMSROOT\bin\perl ResetLoginModule.pl

    (for Windows)

    Then, restart the daemon.

    I did it, but does not work, any idea?

    Hello

    I guess you can try to go through the question on WSC and GBA integration troubleshooting:

    http://www.Cisco.com/en/us/docs/security/security_management/cisco_security_manager/security_manager/3.0/troubleshooting/guide/rbacts.html#wp1043629

    Few things might have gone wrong:

    1 - this command must be run on the server MCS cmd prompt (make sure that you are not on the client computer)

    2 - NMSROOT is the directory were MSC Server is installed. Is usually c:\Progra~1\CSCOpx

    3. you must stop the deamon Manager before performing this action (and restart)

    For example if the directory is the one above to reset the connection locally, you can try the following:

    net stop crmdmgtd---> that stops the daemon Manager (can be done by the services window)

    c:\Progra~1\CSCOpx\bin\perl c:\Progra~1\CSCOpx\bin\ ResetLoginModule.pl---> restores local authentication

    net start crmdmgtd---> restart the Daemon Manager

    Can you maybe try again and let me know how it goes?

  • Dashboard ASA ASDM Cisco ACS

    Hi all

    We use CiscoSecure ACS 4.2 for AAA.

    In our ASA 8.2.5 ASDM 7.3 (1) 101, if connect us with user group privilege 5, we would be unable to see the dashboard of firewall for Top 10 Services / Sources / Destinations.

    Someone knows how to have the privilege of established, essentially the Group of users that we have only in read-only, but can see the Top 10 services/sources/destinations edge ASDM

    Thank you very much

    Hi David,

    Yes you are right with privilege 5 you would be able to make these changes.

    You can use one of two methods of authorization in order to work around this limitation:

    Local database: configure command on the security privilege levels
    device. When a local user authenticates with the enable command (or logs
    with the command login), the security apparatus put this user in the
    level of privilege that is defined in the local database. The user can then
    access controls at and below the user privilege level.

    Note You can use the authorization of local control without all the users in local
    without CLI and database or enable authentication. Instead, when you enter
    enable command, you enter the enable password and security
    device puts you in level 15. You can then create enable passwords for
    all levels, so that when you enter enable n (2 to 15), security
    device puts you in the level n. These levels is not used, unless you put
    local command authorization (see "setting up order Local
    Authorization ".
    http://www.Cisco.com/c/en/us/TD/docs/security/ASA/asa80/configuration/gu...

    GANYMEDE + server: GANYMEDE Server + (ACS), to configure the controls that can be used by a user or a group after they authenticate to access CLI. All the commands that a user enters in the CLI are verified with the GANYMEDE server +:

  • How can I use Cisco ACS to save Shell commands

    Hi guys, pleeeease how can I configure Cisco ACS to do command authorization on my Cisco 3660 router. I get the accounting logs and authentication but no newspaper that show orders issued by users - shell and it's the most important paper that I need. I read materails and download articles on the site of Cisco... but the thing is still does not give me the papers.

    I have these lines on my router:

    ...

    AAA authorization config-commands

    AAA authorization exec default group Ganymede +.

    AAA authorization commands 15 default authenticated if

    AAA authorization network default group Ganymede +.

    ...

    It's funny, when I turn on debugging of the authorization of the AAA on the router, it shows me every command being sent by the user on the debug log. But nothing shows under Administration TACAC + on the Cisco Secure ACS. What is responsible for this?

    *****************************************************

    I installed the trial version of the Cisco ACS 90 days and made all necessary settings and I have to say I like what I see already. I'm opening moves to recommend the product to purchase. Thank you guys, I got about the features of this ACS software through this forum, keep up the good work. I recommend the software for those who need to have adapted to the management reports Security Audit logs.

    If I understand what you're asking correctly, the answer is not in the authorization, that it is in accounting. I set up on my routers and send to ACS orders that level 15 privilege users enter on the router.

    orders accounting AAA 15 by default start-stop Ganymede group.

  • Cisco ACS 5.1 and RSA Authentication Manager 6.1

    Hi all

    We recently had a Cisco Secure ACS 1120 and I improved the Unit 5.1 5.0 with all your support

    Now, I need to integrate Cisco ACS 5.1 with RSA Authentication Manager 6.1. I have config file of RSA ACE Server successfully downloaded and exported to 1120 ACS.

    I also added as NetOS Agent ACS in the RSA server during the process, I found a few warnings. The ACE Server is not able to resolve the IP address to the name (is it necessary?).

    I have not created any file of secret key for communication between FAC and RSA and I used encryption is FOR.

    Now, when I log into ACS and search for devices in the identity store sequences I am not able to get Sever Token RSA.

    Let me know what was wrong, where can I fix and also please tell me what is the communciaction between the RSA and ACS?

    Hoping that you guys help me as usual when I'm in a hurry...

  • Cisco ACS, multiple CA, assignment of VLAN relevant to the domain

    Hi all

    I searched for a solution to a specific customer requirement.

    I want authenticate users with certificates from different RootCA wireless and assign them to one VLAN based on their field?  Ideally, using the same SSID and a Cisco ACS server.

    Is this possible?  Has anyone seen that it works?

    I realize that the ACS can have trust company for the relevant RootCA (dunno what version is needed for this?).  And that assignment VLAN is also possible to a unique SSID based on RADIUS attributes.  But I am not sure that these parts would fit together?

    Would appreciate some advice!

    Thanks in advance

    Rob

    Hello

    Yes, this is possible. I suggest that you implement one by one to make sure that everything works, but no problem to do so. All recent versions of ACS allow this.

    You can do mapping group from ad groups (a group for each area, so if you want to) and assign the vlan based on the mapping of this group.

    GBA can trust several certification authorities and authenticate users with certificates of all these cases. It's just a matter of import these number certificate in the trust list.

    And you can assign the vlan and use only one ssid as well.

    I can't guide you on the procedure that it depends on which version you have and if you have IOS ap or WLC, but it is basically each function separated as in the config Guide and just used all together.

  • Integration of Cisco ACS and Cisco NAC Manager - downloadable ACLs

    Hello

    I have Setup Cisco NAC in my environment. These are all works well. The users themselves will get authenticated via Cisco NAC Manager. The Cisco NAC Manager meets with Cisco ACS for the part of the user database. These are all works well. I would like to activate downloadable ACLs. I tried to use the CISCO-AV-PAIR method and creating a downloadable ACL entry in the shared components, but nothing works. It's either I'm doing wrong or this configuration of the mine does not support downloadable ACLs? Please advice kindly.

    Hello

    It is not possible.

    You cannot push the ACL in the NAC manager.

    If you make the Radius of NAC authentication manager, you can do is create roles the NAC Manager, and on the roles you define traffic strategies.

    Using the Radius attributes you can then map users to roles.

  • Cisco ACS AD authentication

    Hello!

    IM currently deploying Cisco ACS 5.4 on our netwrok and I'm looking for in some additional measures to ensure authentication and authorization to the devices.

    I would like to ask if anyone has any advice on the following as I may have been embarrassed to do this way myself.

    OK the users that now are authenticated with an external identity store (Active Directory). I would like to know if theres a way also to authenticate these users or allow them to ACS so that when the IT Department adds a user who should not be in a group, but the group is authenticated to a set of devices, this user will be nto be able to access devices.

    A simpler explanation is as follows.

    E.t.c groups are ficitonal

    I have group in AD called "Engineers" that contains 2 users, user A and user B.

    Engineers have a shell on ACS profile that gives permissions/privileges superuser on the devices.

    However, Active Directory is managed by the it Department that could be social designed to add a C user in this group.

    What I need to know is a way to allow the user has and user B to access devices while maintaining the profile of the shell with the Group of ads "engineers."

    I am aware of the conditions is devoted to profiles/authorization rules. Is that mean I have to create both local users and assign their passwords as well?

    Im a bit confused as you can see it...

    Any help will be greatly appreciated!

    Thank you!

    Because user C would be added to the same group that already contains users A and B and the authorization rule is configured to grant access from root of users A and B belonging group engineering, then user C will also be granted this access.

    ACS has no way to know what the users are members of the engineering group, nor can it detect that the user C has been successfully added.

    If you want to use the credentials of the AD and at the same time maintain a canonical list of users for ACS check, you will need to create local GBA users, as you suggested above.
