Fix:

Change the security in the ESB.Portal web.config.

In the web.config change the security mode for the webBam webHttpBinding to match the correct security for your portal. For more information review: http://msdn.microsoft.com/en-us/library/ms731362.aspx.

To get mine to work I changed:

<webHttpBinding>

<binding name="webBam" maxBufferPoolSize="5000000" maxReceivedMessageSize="5000000">

<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

<security mode="TransportCredentialOnly">

<transport clientCredentialType="Windows" />

security>

To:

<webHttpBinding>

<binding name="webBam" maxBufferPoolSize="5000000" maxReceivedMessageSize="5000000">

<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
