Secondary ACS authenticates not to dynamic users

Hi all

I have two ACS server for windows with version 4.2. My problem is that, if the primary ACS server is down, dynamic users from the database windows in unable to authenticate with the ACS secondary. Please note that if a user is added to the ACS, this user can authenticate with the windows database. Only the dynamic mapping is not the case with the second ACS server.

A quick response will be appreciated.

What is in the database of Windows in both the points of the unknown user policy? Dynamic users are active under the unknown user policy?

Are these servers ACS for Windows or the ACS SE with a Remote Agent installed on a member of the AD Server?

If they are remote Agents, see the external database > Windows Configuration > selection of the Remote Agent. The same remote Agent is selected on both ACS servers?

Please be aware that if you change the order of the RA he would remove all your group mappings.

  • Secondary ACS does not authenticate

    I install an ACS secondary, database replication works correctly.

    But when I try to use the ACS secondary server to authenticate the user, I can't authenticate successfully.

    In reports and activities (ACS secondary), it does not appear anything.

    In primary school, ACS, he failed attempts, I see an "unknown SIN" the ip address of the secondary ACS, it seems only secondary try to use elementary to authenticate...

    Where I'm wrong?

    Thank you

    Hi Daniele,

    It is because the parameter on the acs secondary proxy. On secondary acs visit acs--> configuration network--> table tell proxy---> bring your secondary acs under the front walk to the box.

    That should fix it.

  • Secondary ACS do not authenticate

    I have 2 ACS 1113 devices running 4.1 Build 24 (1). The first is the main and replica nightly on the secondary to our DR. Although in different places, they are both in the same VLAN with no. firewalls or an in-between of the lists to access them. All my devices will be authenticate with my primary ACS unless it is down, in which case they must authenticate the ACS secondary. The problem is that I have no problem with authentication on my ACS primary, but I can't get anything to authenticate to my high school (after the primary decision-making down to test). In trying to authenticate to my high school, I get no newspaper for authentication successful or failed after that my attempts fail. In addition, during my attempts fail, I try to log into devices locally and my authorization fails - again with no journal of the ACS. However, when I remove the NDG in the ACS secondary, I'm able to log on locally on the network device.

    I believe that with the device the NDG in the breast of the CSA, there is a communication omitting my attempts (although it does not connect anything) since I can take the device off that NDG and transmit local authentication. I was running code 4.0 with the same question and thought that the update should fix the problem... but obviously, I have something to do else here.

    Any comments or suggestions would be greatly appreciated.

  • VI does not have dynamic user event

    I have several screw running in parallel. I want to instantly communicate a VI data to another.  I am trying to achieve using user events.  All my screws share a dynamic event via a global variable reference.  When I run the event user a VI, about 80% of the time it is received correctly by the other VI.  The other 20% of the time, the event is not received, and the data is transmitted as planned.  Here is some information on the screws that make the transmission and reception:

    Transmission of VI: front is open, no activity happening on the Panel, no calculation happening.  After I sent the user event, the event loop goes to the waiting state.

    Recieviing VI: front is closed, any activity that happens.

    What a bad way to pass data from a VI to another?  I don't like the use of global variables because you need constantly query variables and you can run in race conditions, but maybe it's what I do.  Does anyone have experience using the user events to pass data between the screws?

    Then I do a registration Dynamics refnum and record worldwide.

    This is most likely the source of your problem. The documentation do not insist on this point (and LV does not apply it), but you should NEVER share event reg refnums between the structures of the event. Each structure the event must have its own reg for node events or your events will go away, as you saw.

    As long as you remember this rule of thumb, the architecture you are using must be fine, although I would usually avoid putting references in globals. You seem to have got a few percautions (high level VI opens to them, made sure to write before running the readers as a writer), so it will probably not break for you, but still.

    Anyway, as others have mentioned, there are also other means of transmission of data between screws autour

  • Disable caching dynamic users of GBA

    Hi all!

    I have a b2 ACS 3.3 (2) what use AD as an external DB. I have experianced, dynamic users created after authentication successful advertising, and these users are serving since the ACS internal database. I did a test environment, and it's the same thing. I improved GBA at 4.0, and it's the same thing.

    I find a mention in the ACS4.0 guide that says the following:

    "Mapped users dynamically dynamically will keep mapped, even when their group."

    mapping settings are changed in a group that is set to disable the cache users mapped dynamically. »

    So my question is, where can disable caching of mapped users dynamically?

    Thanks a lot for the answers!

    Miki,

    This is a feature that is added on ACS 4.2 see notes below:

    http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/release/notes/ACS42_RN.html#wp90436

    Ability to disable the caching of the dynamic administrator users can determine if they want to disable creating dynamic users while using an external database for authentication. Minimum performance disruption occurs to disable the caching of dynamic users.

  • Dynamic user LV 2011 events ignore when you're already handling a

    Hello

    I have a UI which fires def dynamic events to control a process. These events are handled in a vi running in parallel. Say that the user has decided to fire an event of 'start', which is handled by the event handler, and now I would like to than the event handler to ignore all subsequent events, until the process of 'start' is complete. Such as if the user triggers two events 'Start', the other will be completely ignored. Then, when the "starting" event has been processed, events turned back on, so that the user my send another event 'start '.

    How do I do this in labview 2011?

    In labview 2009, I unregisted the user event and then he saved when you have completed the process.

    In labview 2011, it does not. After the cancellation of the registration of the user events, labview all future events, don't even know if you resave the. (This causes my application to freeze, because it receives more events. What is really annoying!)

    Can anyone help?

    Thanks FraggerFox, the technique used in this discussion of LAVA is only useful for control of the façade events and cannot be used for events defined by the dynamic user,.

    I understand the link, rather than event non-registration help unsubscribe feature events in LabVIEW, try passing a null reference to unregister it.

    The trick is illustrated in the example: registry of \general\dynamicevents.llb\dynamically for events.vi

    Consider extending the example: I want to receive a notification of event user as well, all the time. To cancel registration for both events shown in the example above, but not to cancel the registration of the user event, I must use null record. If I call the primitive unregister, I'll eventually unsubscribe to my user and event. Similarly, the use of the global unsubscribe primitive does not work if you have different dynamic events with different life spans.

  • Search ACS 4.2 order unknown user from database

    Hello

    I have several user databases in the search order for the unknown user policy. Ignoring the manual (http://www.cisco.com/en/US/partner/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/UnknUsr.html#wp277530), which States that, after the failure of authentication from the first database (Windows) the ACS does not continue to look for the second database, a RADIUS server. I see that, with the failure in the first user, database stops the ACS research and fails to the user authentication with an authentication failure code "external DB password invalid.

    Documentation not going or is this a bug in the ACS v4.2.1? How can I make the ACS to continue to seek the second database user?

    Hello Roberto,.

    If the external database returns an invalid username/password, then it is intended for ACS is not to check the following data in the sequence and the failure of authentication:

    http://www.Cisco.com/en/us/partner/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2/user/guide/UnknUsr.html#wp277502

    "For authentication requests, ACS applies the unknown unknown user policy to users. ACS does not backup to the known or discovered users authentication failure unknown when user authentication support. »

    If you want that ACS to verify the following database, even if a response from the invalid username/password has been received, you will need to explicitly set this on the external Windows database configuration page, in the section entitled 'Strategy for the unknown user' (but on the database configuration page specific Windows, not covered by the unknown user policy) :

    http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.2.1/User_Guide/UsrDb.html#wp354338

    In addition, on the previous screenshots, I could see that you have configured both as a result of database:

    Windows database

    RADIUS Server token

    So we may be running into a situation where the authentication method used is not supported by the tokens, Radius servers, and therefore impossible to check the second database in the list:

  • Secondary ACS server: waiting.

    I had the following problem. There are 3 ACS servers: 1 primary school in Moscow, 2 secondary school in Moscow, 3 secondary school in Europe. Excellent relationships between servers in Moscow, between primary and secondary in Europe not good: automatic replication is not working properly. All changes made to the primary server does not automatically replicate on the server in Europe (ACS admins, devices). Manually 'Full replication' works very well. Have any ideas?

  • -> Is an interface possible dynamic user see global workspace?

    Hello

    I need to generate an (probably global) workspace overview according to some attributes of the object. I'll get the attributes via a REST call. I would like to be confirmed by an expert here if it would be possible to get a view of working space based on the response of the REST call. It will have metadata attributes that would be used to return the attributes of the object.

    I'm still reading the docs in detail. I just wanted to know if this dynamic user interface generation is possible with the extension WC vSphere framework. If so, I can use this approach to add the extension to the client, otherwise use a normal webapp, which is a standby option - for now.

    Thanks in advance.

    If your question is "can I change some view extension data based on the result of a rest call?"  the answer is no.  Extension data are defined in plugin.xml statically.

    But if you mean "the user interface in an existing view can be triggered by the outcome of an initial appeal rest?  the answer is: Yes, it's just a web application and you can return anything you want in the display.

    And if I did not understand completely your use case, please add Details :-)

  • SpeedGrade does not not with dynamic or stand-alone links.

    SpeedGrade does not not with dynamic or stand-alone links. Projevt cannot be bound, nor a project can be opened from scratch. Opening or creating a file isn't even an option, and I have a huge project to turn in tomorrow! WTH Adobe. I've updated the first CC 9.0.2 and still nothing

    Sorry for the correction, but Adobe (sometimes confusing) nomenclature, it's "Dynamic Link" to AfterEffects and 'Direct link' with SpeedGrade. I explained by engineers that they are two very different processes where the difference in name. My answer... If the processes are so very different, why are the names that could be confusing? "Because they are the more precise terminology of what happens." I think they are the most accurate to spoil the spirit of people, but I'm sure the engineers are smarter about this than me!

    The Direct link process ONLY works when he 'sees' appropriate corresponded builds... for the current coupled:

    CC2015.0.2/build 9.0.2(4) for first Pro;

    CC2015.0.1/build 9.0.1x21 for SpeedGrade

    Then... check your SpeedGrade (wrench, top tab of the 'About' page), making sure it is the correct version.

    Also... If there is a problem with is functional Sg (sometimes these programs need the Cleaner CC Adobe app to uninstall, then a new re - install) you can use the color workspace editing in Premiere Pro... He has a considerable amount of the capacity of the Sg, but not (for an experienced user of Sg) treat the whole meal. When even... you can make a good amount and quite quickly. And this gives you the expanses of SpeedGrade, that are better than the crappy things 'Fast' of this eons PrPro and '3 - Way' color Correctors use... yuck.
