DNN Ver 5.6.7
.NET 3.5
Anyone know of a way to access/update user accounts on a DNN site from another web application?
My goal is to allow customer service to update an employee's DNN password from an intranet app (that includes some other employee related, non-DNN data), but I'm not having any luck. I tried adding a simple web service to a virtual directory (as described here) to the DNN site, hoping the web service would then have access to all things DNN, but I'm not able to create instances of the UserInfoController - it's not instantiating the MemberProvider object.
UserController objUserController = new UserController();
UserInfo objUser = objUserController.GetUser(portalId, userId);
Each time, the objUserController object shows null for DotNetNuke.Security.Membership.MembershipProvider
Both the DNN site and our internal web app are hosted on the same server. Any suggestions are appreciated.
EDIT: In addition to all the DLLs in the DNN bin folder, I also copied everything from the DNN web.config into my web service web.config that looked DNN related
if your WebService is inside DNN, this code must work:
UserInfo objUser = UserController.GetUserById(DotNetNuke.Entities.Portals.PortalSettings.Current.PortalId, userId);
If your intranet app is running on ActiveDirectory, I would look at some of the available ActiveDirectory integration modules.
If you can wait until DotNetNuke 6.2 comes out, it will include a built-in services layer which will allow you to authenticate and interact with DotNetNuke objects like users.
I did this via http://iweb.adefwebserver.com/.
I added a web service method that took advantage of all the user related features in the DNN API (UserInfo, UserController, RoleController, etc.).

(Disclaimer : I'm just getting started with Django, and with web dev in general)
I have a backend app that stores different kinds of resources. Some are public and some are private. The application is accessible only to identified users. A GraphQL API allows me to access the resources.
On another server, I'd like to create a website that will be accessible to everyone. I want to use Django to create it.
The website will display a list of resources tagged as "public" in the backend app, with a pagination system and, say, 20 resources by page. The CSS will differ from the backend app and there will be a search section.
From what I understand, I should be able to retrieve the data through the GraphQL API, but I'm a bit confused here. All the documentation and tutos I can find about Django and GraphQL seem to be about setting up a GraphQL API server with Django. All I want to do is to build custom queries and to display them on my different html pages.
How can I do that? Where should I start?
You should connect your project with a GraphQL client. As per my research, I have found that there are implementations and examples for graphene-mongoengine in Flask (Flask has a direct GraphQL client).

For Django you can check this out
Edit- I was able to get the data from my database with python-graphql-client. Now I am able to display them in my template.
Let me know if this helps
Essentially, I'm wanting to create an Oauth Client as an App so I can get data from Dynamics for multiple customers. Does anyone know if this is possible to do in AppSource or do you know of another way?
I have a service that will be served in a cloud different than Azure so there really isn't anything for me to submit as an App and I really don't want every customer to have to setup their own App that gives my service the privileges/access it needs, but it's looking like I may have to.
It sounds like you'll want to register an app with Azure AD (the OAuth2.0 service/identity provider for work and school accounts), and create a multi-tenant app. Then you can configure this app in the Azure Portal to get permissions to the APIs the app wants tokens to call (in your case Dynamics or the Microsoft Graph).
Once this app is written, you can code up your app using one of the Azure AD Auth Libraries. Here's some sample code for a .NET web API. You can find more code samples on Github and search active directory. Moreover, the Azure Active Directory Developer Landing Page is a great place to look for more resources on doing all of this.
I am very new to SharePoint development as well as SharePoint overall, so I apologize if this question seems like a no-brainer. I'm currently working on a SharePoint 2013 app and I'm wondering if it's possible to make a call out to some URL from within the SharePoint environment. Basically, I want to do this within an event receiver after some action is done to a list, and from there I want to make a call to some web service on my server to update my system. Using the REST API to poll the SharePoint server isn't a good option for this scenario since it won't scale very well.
When dealing with SharePoint 2013 apps you can access any resource using standardized APIs. In addition to REST SharePoint is offering the JS Client Object Model (CSOM).
In order to access data from another web than the current one, your app needs the permission to interact with the entire tenant.
If you're trying to query data from another host, you have to use JSONP because of the same origin policy.
if you are building an app using the "new App Model" for wiring up Remote Event Receivers it is possible to do anything, in which your app hosting framework/environment allows you to. If you are building a Classic App (Farm Solutions) you'll have access to perform operations which are allowable from the SharePoint servers directly...typically this is a lot as GAC deployed assemblies are granted full trust.
depending on what you are trying to do and what kind of resources you app will consume. I'd consider moving the dependancies away from SharePoint and building using the new App Model versus the older farm solutions. As you sound like you are starting in SharePoint, this gives you an opportunity to learn the new ways of doing development for SharePoint.
Lastly, you might consider building a workflow. Not sure what kind of app you are building but the new workflow capabilities include actions which can make RESTful calls. Potentially making your application a "no code" solution. Again it all really depends.
I'm getting an error when attempting to call SharePoint's webservices on one of our platforms. To start, we have Development (DEV), Testing (QA) and Production (PROD) SharePoint servers. The QA and PROD servers are pretty much identical. We have an ASP.NET web service that sits out as a seperate application on each of them. Our data entry forms hit the web services to insert/update into a SQL database and in some cases make calls to some of SharePoints web services (lists, dws).
We’re having trouble calling SharePoint’s web services on PROD from our web services however, have no problems on QA(or DEV). In our web service code we have a web reference to the SharePoint web services (lists and dws). We attempt to call these web services to create list items/folders when a new entry is made through one of our forms. On QA, there is no problem creating the list items/folder. The form is filled out, calls our web services – which call the SharePoint web services and the list item/folder is created.
On PROD we get the following error when we attempt to call the SharePoint web services:
Unable to connect to the remote server
at System.Net.HttpWebRequest.GetRequestStream()
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
...
However, to make it more interesting, if I call the PROD SharePoint web services directly from my personal computer I have no problem creating the list items/folders. We only have the problem when our web service attempts to call the PROD SharePoint web services. We’ve looked through many different web.config files looking for differences on QA and PROD and are yet to come up with anything.
If anyone has any pointers, they would be greatly apppreciated. Thanks.
Update: I just attempted to refactor the above method to use the SharePoint Object Model API and I'm getting an unauthorized error. When using the Object Model API the credentials do not seemed to be passed properly, because it's attempting to use the MOSS Server credentials. Is there any way to tell it which credentials to use as you do with the web service api?
docLibList.Credentials = System.Net.CredentialCache.DefaultCredentials;
Thanks.
Sean,
I'm not sure I completely understand your calling pattern, but if you are indeed looping back to web services on the same box, you might be running into the infamous loopback issue:
https://serverfault.com/questions/32345/ie-8-authentication-denied-on-local-sharepoint-site/32485#32485
In short: executing hostname-based HTTP calls that loopback to the server from which they're issued can get blocked. If the loopback issue is in-play, you'll be able to call the web services in PROD from another box ... but not from the PROD box itself (i.e., looping back). I think this is consistent with the behavior you described above.
If Windows patch levels are different between your environments, it might explain why your code is failing in PROD but not in your other environments.
I hope this helps!
This probably is not the problem, but is your reference to the web service pointing to the production server correctly. I had a problem before when trying to access a SP service that was referenced incorrectly. The dev server I was pointing to was on a seperate domain and could not be found.
Regarding the update to your question about the unauthorized error using the object model:
Depending on the context that your code runs in you will sometimes need to elevate privileges. See this Elevation of Privilege MSDN article for details (also note the community comment at the end). There's also a Visual How-To.
Another method is to create a new SPSite object using a SPUserToken object. There is more information in this blog post by Daniel Larson. For the system account this would be done with the code:
SPSite site = new SPSite(SPContext.Current.Site.ID,
SPContext.Current.Site.SystemAccount.UserToken);
By the way, this would be better in its own question next time so that it can be correctly voted and answered.
So here is the scenario:
I have a MOSS 2007 box and I want my clients to be able to access a SharePoint site via the internet. I am told that I will be using an IPA and AD for authentication. However I have a DB outside of SharePoint that holds various business data and I want to use Web Services to access the data, manipulate it, and send it back to SharePoint via web parts.
The issue is that, from what I understand, I am going to have to authenticate the AD user every time a request to the Web Service happens. Obviously I dont want to do this every time because they have already authenticated to get onto the site, however I do want each call to have some form of security so its not open calls to my db. I do plan on having other applications access this service outside of SharePoint, so I dont want to have to reinstall the service for each application or even again.
Has anyone had to perform this task or something similar or do you have any suggestions on how to do this?
Thank you in advance and happy coding!
Why not just deploy the webservice to Sharepoint using a Sharepoint solution and a Feature.
That way it will be running under the sharepoint app pool and all authentication is done by sp.
Edit:
Seeing that SharePoint should not be in "control" (as stated in the comment), you should create the webservice, and run the application it's under in as using Windows Authentication. IMHO you should create a WCF Service. The, using the information found in this article you make the Service authenticate users against the AD usergroups they are in. see the "Security: Authentication" section of the article.
Then in Visual Studio you create a webpart and add a service reference to the project, pointing to your newly created Service. Have the webpart perform the needed logic (i.e. display data etc.)
Deploy the webpart to SharePoint using a SharePoint solution (.wsp files, created with WSPBuilder). Google for SharePoint + wspbuilder + tutorials. The solution should contain 1 feature to deploy the webpart. WSPBuilder integrates with VS and allows for the creation of WSPBuilde project. add a webpart feature item to the project (it will create the xml (deployment related) and code file for the webpart.
