How to Connect custom web app to CRM 2016 Online

(1) ShareShare
ReportReport
Posted on by Mariusz

I am trying to use Microsoft.Xrm.Tooling to connect my custom web service to CRM 2016 Online (office 365) but I am getting:

"Unable to Login to Dynamics CRMOrganizationServiceProxy is nullOrganizationWebProxyClient is null"

 

Same code works as console app without any issues.

    It was a problem with permissions of IIS application pool service account, I haven’t looked deep into that so I don’t know exactly what permissions my service account is missing but since I changed app pool to ApplicationPoolIdentity I am able to connect.

     

    Thanks anyway.

    Hi Mariusz

    Could you please tell what exactly you did  in order to change  app pool to ApplicationPoolIdentity? I am new at IIS,  have the same issue you had and do not know even from where to start.  

    Z góry dziękuję!

    After an investigation I found out that account which is used by IIS app pool must have windows user profile (files/folders). I believe that Microsoft.Xrm.Tooling is using user profile location and if you use service account that doesn’t have user profile it won’t work. Details on how to configure IIS app pool identities are here:

    I also have a very similar problem and it occurs when running from my webapi 2 project and in the cloud on my webapp

    I create the client like so
    var serviceClient = new CrmServiceClient(AuthType=Office365;Username=<USER_NAME>; Password=<PASSWORD>;Url=https://<HOSTNAME>.api.crm4.dynamics.com/XRMServices/2011/Organization.svc);

    Often I have the following properties on the client once instantiated, that means I get a null ref exception when I try to use the client
    IsReady = false
    + OrganizationServiceProxy null Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy
    + OrganizationWebProxyClient null Microsoft.Xrm.Sdk.WebServiceClient.OrganizationWebProxyClient
    LastCrmError "Unable to Login to Dynamics CRMOrganizationServiceProxy is nullOrganizationServiceProxy is nullOrganizationServiceProxy is nullOrganizationServiceProxy is nullOrganizationServiceProxy is null" string

    I found this article that helps me connect in Azure blog.vertica.dk/.../crm-2016-unable-to-login-to-dynamics-crm , but I still have the same problem in my local webapi app unless I stop my iis express process then I can SOMETIMES connect once then on the second request IsReady is false etc.

    The article says to set create the following app setting in Azure WEBSITE_LOAD_USER_PROFILE = 1 (true), and thats working for me
    Locally in my webapi app I have edited my .vs\config\applicationhost.config so that my app pool has the same setting i.e. <processModel loadUserProfile="true" />

    If I could get some help to be able to connect consistently in my local project it would be great

    Example
    Request sent from POSTMAN in my browser to webapi 2 project on my machine, connecting to CRM 2016 online

    I'm having a similar issue when trying to use CrmServiceClient to connect to an Office 365 CRM 2016 online org inside a powershell cmdlet. I'm guessing it is a similar issue, where the powershell environment likely doesn't have the right access to something. Anyone narrowed this down further to the root cause and maybe have a thought that might help?

    Try with this:

    var serviceClient = new CrmServiceClient(AuthType=Office365;Username=<USER_NAME>; Password=<PASSWORD>;Url=https://<HOSTNAME>.api.crm4.dynamics.com/XRMServices/2011/Organization.svc);

    i.e.

    var serviceClient = new CrmServiceClient(AuthType=Office365;Username=<USER_NAME>; Password=<PASSWORD>;Url=https://<HOSTNAME>.api.crm4.dynamics.com);

    For reference, you can enable an app pool to 'Load User Profile' by reading this post

    I was getting following error while connecting Dynamics 365 (Online trial) instance from Azure Worker Role application (C#).

    CrmServiceClient conn = new CrmServiceClient

    ("AuthType=Office365;Url=https://<orgname>.api.crm.dynamics.com;Username=username@<orgname>.onmicrosoft.com;Password=xxxx");

    Error:

    "Unable to Login to Dynamics CRMOrganizationServiceProxy is nullOrganizationWebProxyClient is nullOrganizationWebProxyClient is nullOrganizationServiceProxy is nullOrganizationWebProxyClient is null"

    Resolution:

    Included following lines under <configuration> in application configuration (app.config) file and I am able to connect Dynamics 365 (Online trial) instance.

    <system.net>

    <defaultProxy useDefaultCredentials="true"/>

    </system.net>
