Thread: Adjusting HTTP Headers in Download for SharePoint 2010 Node

    Default Adjusting HTTP Headers in Download for SharePoint 2010 Node

    Hello,

    I have a need to turn a specific HTTP Header to false in order to successfully connect to a SharePoint site from the node but I am unsure of what Parameter to use in order to accomplish this.

    Looking at the Java tab of the Download For SharePoint 2010 in the base library I see an error message that reads "{{^MessagePrefix^}}.invalidHttpHeader" {{^MessagePrefix^}} is set as "brain.node.sharepoint.download"

    Having this error message leads me to believe that HTTP Headers can be adjusted from the node but where??

    Thanks,
    Kevin

    Hi Kevin,

    I assume your request to set HTTP headers in the SharePoint 2010 nodes refers to working with SharePoint 2010 sites that are configured to use 'multiple authentication providers'.
    SharePoint 2010 has a 'feature' whereby web service requests that are set to authenticate the user via windows authentication are denied when the site uses 'multiple authentication providers'.

    https://msdn.microsoft.com/en-us/lib...ffice.14).aspx

    The resolution for this situation is to include the X-FORMS_BASED_AUTH_ACCEPTED header in the HTTP request with the value set to f - which causes the SharePoint site to authenticate the user with their Windows credentials.

    The SharePoint 2010 nodes were updated in LAL6.1.44.0 / LAL 6.0.44.0 to include the above header in the web service requests sent to the SharePoint 2010 site.

    The latest release of LAL can be downloaded from the Lavastorm website: http://www.lavastorm.com/lavastorm-installers/
