Linking asp membership to an external system

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :ASP.Net


I've had a look through the forums but I couln't find a concrete answer - I found some things that point me in the right direction but I would like to just ask for some clarification.


My requirements are as follows:

I have an external system, with an API that allows me to log in a user, and returns whether or not it was successful. This can only be done through the API, it can not be done with a direct DB connection.

I want to create a site that can only be accessed by someone who has a login to this external system. 

Through the site they will only be able to log-in, there will be no possibility to change password etc, this is all done in the external system by an admin.

I like the ASP membership system, and the way it works with anonymous and member views and would like to continue to use it. My question is, how do I do this? Do I create a custom membership provider that overrides all the methods of the usual membership provider? And how will the fact that all I actually want to do is allow the user to login affect things? There will be no ability to change details etc.


Thanking you in advance, and sorry if my question is a bit general or has already been covered in detail before.

SharePoint 2010 and external file system - DocuShare


I am working with a client that is looking for a SharePoint (2010 Standard) solution for CMS and document management.  Initially they intended to migrate thousands of documents from Docushare to SharePoint, but are now asking about leaving the documents in the current file system instead of migrating them. Can SharePoint work (allow access, controls, search, etc) with documents stored on external file systems?  How would this work?  Drawbacks, costs, tools needed all helpful.


Best way to delete a record in SQL aspnet membership system



I'm trying to include a method in my application (for a delete button) that completely deletes a user from all relevant tables in the entire aspnet membership system in SQL. Is there syntax I can use to combine the following Delete statements -- or do I have to include each of these individually on my code behind page, as per below?  Thank you.

DELETE FROM aspnet_Profile WHERE UserID = @UserID
DELETE FROM aspnet_UsersInRoles WHERE UserID = @UserID
DELETE FROM aspnet_PersonalizationPerUser WHERE UserID = @UserID
DELETE FROM aspnet_Membership WHERE UserID = @UserID
DELETE FROM aspnet_Users WHERE UserID = @UserID

external content types are not available. Contact your system administrator.


I add an Business Data Actions webpart to the webpage. when i' m  going to select an external content type, it appears this ' external content types are not available. Contact your system administrator.'

Does Microsoft Membership provider supports internal and external users?



I am developing a web application for internal users and I was asked to implement security model. I suggested using Microsoft Membership provide model, so one of my team member raised a question stating that this model doesn't support external users.

Is it true statement? if not, please provide me links or samples to achieve this.




System Development Life Cycle

The Systems Development Life Cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the spiral model. Mostly, several models are combined into some sort of hybrid methodology

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Problem upgrading to MVC3 - System.Web.Routing



I'm trying to upgrade to .NET 4 and MVC 3.

When trying to compile my project, I get the error:

Error 1 The type or namespace name 'Routing' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) C:\Users\spencer\Desktop\weblauncher\Common\MVCConfig.cs 4 18 Common

The type or namespace name 'Routing' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

I do have the System.Web.Routing in my references for the project.

BUT - when I try to view System.Web.Routing in the OBJECT BROWSER, nothing is inside!  The System.Web.Routing namespace is not in there - the entire thing is empty!  Could it that the dll is corrupted?  I tried to reinstall the .NET 4 and MVC 3 stuff, but its still empty!

The dll is coming from here:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Routing.dll

Multiple membership providers



In my web.config I have:

        <add name="ADProvider1"
        <add name="ADProvider2"

If I just have ADProvider1 it works, when I add ADProvider2, even though for testing I only use ADProvider1 I get an error: "Unable to establish secure connection with the server"

Am I adding the second provider to the membership section incorrectly?



Replacement options for Membership


Hi everyone,
     I tried to use Microsoft's Membership option for signing up new users and authenticating them on subsequent pages, but it has not worked very well. The biggest issue has been with the REMEMBER ME function. With this checked, I am randomly logged out in the middle of some functions and some pages always show me as not authenticated, while others properly show me as authenticated. I built a site based on VB.
I was wondering what other people are using ro register users and monitor authentication and also if anyone has had better experiences with other solutions.

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPerm


Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help. 

Pass ASP.NET membership identity object across domain?


I am trying to figure a way to SSO with ASP.NET membership and role model.

I can implement custom membership provider which consume web services hosting on a server.

With encryption of data. No problem.

But my question is, If I sign on a website with my provider, got my identity object on that application,

could I pass it to another website on another domain which use the same provider and by doing so, do not need to login again?

If this is possible, I am going to implement this solution. Please tell me what's your take on this.

Membership Provider Conn String


Hello. I've bee successfully using the Asp.Net Membership Provider in my VB.Net 3.5/SQL 2005 web app for a year now (Site A). However, I've added 2 new sites (B and C) (both with their own DB) and now I see a problem. It looks like users that get created for sites B and C also get created in site A. Roles that I create for B and C only get created in A. I think it is a conn string problem.

When I created A, I adde the conn string to my machine.config (not sure why I did this or if it is even needed)...


         <add name="LocalSqlServer" connectionString="Data Source=VS689\SQLEXPRESS;Initial Catalog=SiteA;USER ID=sa;PASSWORD=123456"/>

System.IO.Packaging is not visible


I am new to ASP.net, I installed VS2005 and IIS 5 on my PC and set up my first website using IIS (not the embedded webserver in VS).

For some reason I cannot find the Assembly: "System.IO.Packaging", please let me know if I am allowed to use it in that medium and how can I reference it?

Thanks in advance.
