Security

Hi,

I'm trying to use the ClearPass SOAP interface but am running into a few issues.

I am coding in VB.NET and have imported the Service Referance from my ClearPass Guest as https://10.21.4.4/guest/soap_guestmanager.php?wsdl

I am able to use the Referance in my VB project and followed the guide to setting up a basic command.  Using Ping as an example i am getting an error complaining about "GET" used instead of "POST".  

Does anyone have any ideas?

VB Code

  Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim client AsGuestManagerWebServiceClient = NewGuestManagerWebServiceClient

        client.ClientCredentials.UserName.UserName = "CaptivePortal"

        client.ClientCredentials.UserName.Password = "xxx"

        Dim PingRequest As New EmptyType()

        Dim PingResponse As New ResultType()

        ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf CertificateValidationCallBack)

        PingResponse = client.Ping(PingRequest)

        MsgBox(PingResponse.error)

    EndSub

    Function CertificateValidationCallBack( _

ByVal sender AsObject, _

ByVal certificate As X509Certificate, _

ByVal chain As X509Chain, _

ByVal sslPolicyErrors As SslPolicyErrors _

) AsBoolean

        ReturnTrue

    EndFunction

Thanks!

Did you ever get this issue fixed Eric?

Hi, noticed this post and have a similar problem (?). I just dipping my toes in the water here and my code is not half as fancy as the sample above - I'm using powershell. However, I end up with the same error message "Invalid SOAP request: HTTP method 'GET' is not POST" . If someone can spot my (obvious) mistake, I would really appreciate your input!

$user = "user"
$pass = "password"
$pair = "$($user):$($pass)"
$bytes = [System.Text.Encoding]::ASCII.GetBytes($pair)
$base64 = [System.Convert]::ToBase64String($bytes)
$basicAuthValue = "Basic $base64"
$headers = @{ Authorization = $basicAuthValue }
