    Hi all

    we are having an issue with the captive portal, while using AD as authentication source

    if We use the guest repository our portal is working ok. 


    Ir we use AD repository we get a login error, like invalid username or password.

    What could be the issue?


    regards

    also check the event viewer for any entries

    6.9.10

    I do not see any entries regarding the guest service with AD. Seems that the requests are not coming to clearpass correct. I only get the IP address correct and the our guest portal. AS I put some AD credential it comes back again to the same login portal saying invalid user /password

    Hi,

    Did you enable 'pre-auth check' on Guest Page?  With that option ClearPass check credentials against AD. But you have to create an 'Application Authentication' service to serve this request.

    pre-auth check can be RADIUS or App Authentication. It can be edited in guest page editor. Imo you should use "RADIUS -- check using a RADIUS request". And you need to create a Radius service on policy manager which include Auth source as your AD to handle your RADIUS request. Or you can use App Authentication in the same way as RADIUS.

    Hi,

    I am already using guest service with mac caching with local user database.

    You are saying that I need to create another service for radius request??

    When I test a client machine to connect I get welcome by the captive portal with an initial guest role, when I input the credentials it loads and then it send  back to the captive portal with an "Authentication Failed" message.

    as you have mentioned, you have pre-auth check = App Authentication on your weblogin page.
    you have mentioned that your guest users authenticate fine.
    This means that you have a service of type = Aruba Application Authentication, this service does the pre-auth check
    so in this service do you have AD auth source as well?

    Pre-auth CPPM service should look something line this

    Hi,

    I will check  tomorrow , but I think that service I don´t have.
    I only have a setting under Clearpass Guest page enabling pre auth check.

    But I will see that and get back to you guys

    Thanks

    Hi All

    seems working now
    I had already to services running Guest mac authentication and also Guest user authentication with mac caching with local DB

    What i needed to do , to get AD repository to be accepted, was to add on Guest user authentication with mac caching Service the AD repository and also to go to the guest management under CLearpass and on the "pre auth check" setting change it to " radius --check sing radius request"

    Now seems ok
    Regards and thanks
