Forms based users being prompted for windows authentication login for My Sites photos in user lists

  
Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this?

Oulook.exe hangs when Domain User launches application through Interop windows 2003 sp2

  
Hello,I have a problem using Interop.Outlook on a win2k3 sp2 server. For windows 2003 version prior to sp1 i could use a specific identity for application pool and i had no problems launching outlook.User was authenticated and delegated correclty. With sp2 the Outlook.exe process is launched by the domain user specified as identity (also visible on Task Manager Processes) but no exception or time out is ever thrown.  The only way that i can make this to work is when i set impersonate=true in web config (without setting userName and password as this would have exactly the same affect with the application pool identity).Are there any permissions that i can set to overcome this?Help would be greatly appreciated.

Adding Current Windows User to Database Encounters Existing User with Same Login

  

In VS2008 in debug mode, I am using SMO to programatically change the users and permissions on a database. Windows authentication alone is being used. I need to limit access to a administrators group and the current user for whom the database has been dynamically created during the first run of the application within their current Windows environment on the machine. I have no problems creating and assigning the administrators group, but when I try to create the user using the environment's UserDomainName and UserName variables (which would be my creditals) I encounter an inner exception "The login already has an account under a different user name". Before doing running the app, I manually have checked the local server for user and logins with my credentials and programatically looked at each login but have not found any matching credentials. 

Insights and suggestions appreciated.

SQL Server 2005 random login failures for windows forms application

  

One of our VS .NET 2008 windows forms applications runs from multiple client machines. The application randomly has login failures from random machines and from random places in the code. The login works almost every time but about once every fifteen minutes an error shows up in SQL Server error logs from a random user. We are running a clustered SQL Server 2005 system and the database is in 2005 (90) mode.

The following error appears in the SQL Server error logs:

Login failed for 'App_Login'. [CLIENT: XXX.XXX.X.XXX] Error: 18456, Severity: 14, State: 16.

The following error is what the client sees:

Windows 7 - User needs to login again in sharepoint

  

Hi there,

i hope this is the correct forum for this question. I need help with this issue:

Every Morning, a user [Windows 7/Office 2007/IE 8] needs to authenticate again when he opens sharepoint for the first time.

In the IE-Settings i tried to put the the sharepoint site to the trusted sites and set the authentication to automatic authentication with current user and password.
That did not help. I also tried to put the sharepoint site to intranetzone  aswell but that did not help either (automatic authentication enabled).

When i set these settings for a Win XP-User, it works like a charm - no extra authentication for the sharepoint will pop up. So i think its something with windows 7.
I've heard about some registry values to be set. But to hack something into the registry of a customer pc seems to me like the last exit.

Are there any other (better) solutions/settings which i can try ?


How to hide SQL Server password from user in an Windows Forms Application?

  

Using - VS 2005, SQL Server 2005 Express, Windows Forms Application

Problem-

I am unable to find a way that hides the password to connect to database in case of a Windws Forms Application.

- app.config is accessible to the user, so connection strings an be read.

- app.config can't be encrypted as in case of ASP.NET applications

- hardcoding the password in the application in connectionstring still makes it possible to be discovered by a user

Run windows application as another user

  

Hi,

VS2010, C#,Win XP

 

I am trying to force an application to always run as another user. Even when the user double clicks the exe it should run as a specific other user on the system.

 

I tried switching the CurrentPrincipal value of the thread that the application runs on by taking the token from LogonUser. Although that did not return an error, it still did not seem to be running as the other spcified user.

 

Please help


Application Architecture in Windows Forms 2.0

  
Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Application Architecture in Windows Forms 2.0-Single-MDI Applications

  
Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.

SqlServer - Windows Account to install Application from Gallery

  

Referring to this tutorial: http://www.asp.net/webmatrix/tutorials/download-and-install-an-asp-net-application

I selected umbraco cms and got this wizard:


I already have Standard Sql Server 2005 on my machine which I wanted to us for above DB and not SqlExpress.

I did not remember "sa" account pwd nor I use explicitly any account to connect to my Sqlserver. I use Windows Authentication account i.e implicit authentication. So I created new account and gave all rights and used it in the above wizard and was able to install the database after some struggle.

My question is: What if I want to use my Windows Account to install the database above? Why the wizard don't have any option to use Windows Integrated Authentication?

Note: I can create the DB with external user I created, just looking specifics for using Windows Authentication for above installation.
