    Hello all,

    I have a problem logging in to the Office 365 Sharepoint Online from CRM Online.
    I have found usefull classes like     MsOnlineClaimsHelper that logs in a user to Sharepoint Online as described in this post http://www.wictorwilen.se/Post/How-to-do-active-authentication-to-Office-365-and-SharePoint-Online.aspx

    My plugin works fine in an Onpremise environment but when uploading the plugin to my CRM Online environment, i get the following message:

    $exception         {"The WSHttpBinding with name WSHttpBinding failed validation because it contains a BindingElement with type System.ServiceModel.Channels.TransportSecurityBindingElement which is not supported in partial trust. Consider disabling the message security and reliable session options, using BasicHttpBinding, or hosting your application in a full-trust environment."}               System.Exception {System.InvalidOperationException}

    I found that changing the web.config could solve this issue but as you know, this is not possible on the cloud ?

    Do you have any idea ?

    Thanks

    Fab

    Hello,

    Unfortunately plugins which work in CRM Online are limited in their functionality and namespaces and assemblies that can be used. To work with external webservices you will have to use HttpRequest/HttpResponse - http://technet.microsoft.com/en-us/library/gg509030

    Hello Andrii,

    I used 3 others assemblies in my project Microsoft.IdentityModel.dll, Microsoft.SharePoint.Client.dll and Microsoft.SharePoint.Client.Runtime.dll and I merge them with IlMerge before registering my plugin. This work perfectly but the problem comes when doing the authentication on Sharepoint Online and I face this problem only when I am on CRM Online, there is no problem on my local server. Is there a way to configure binding to basicHttpBinding on CRM Online ?

    Hello,

    I'm afraid that you would not be able to work with external webservices because in On-Line your plugin registered in sandbox mode and this means that possibilities of your code are limited.

    Ok Andrii, thank you for your support !

    It makes sense now. It is not possible to query external webservices while working in sandbox mode. This mode is very restricted :-(

    Regards.

    Hello,

    Could you please elaborate a bit on your reply? As far as I understand you are able to access external web services even in a Sandboxed plugin (according to the SDK). What makes accessing SharePoint Online specific so that it does not work in partial trust?

    Thank you in advance.
