If/then Based User And Password Authentication?
Apr 17, 2009I am writing a program that accepts a user name and password (the password must show up as *s). The user gets three tries to enter the correct information before the program is closed. So far I have the password showing up as the password in clear text the first time and in *s the next two times. The authentication also fails even when I use the correct user name and password which are password and user for now.

[2010] Remove User Password [Windows 7]?
Feb 1, 2011I have already build a application where you type in your username and password and it changes it to the specified password. Now I want to make a "User password remover" application. (It should be the same as "Control PanelUser Accounts and Family SafetyUser
AccountsRemove Your Password").
The program should check:
1) Which User is currently logged on and using the program.
2) Check if the User has a password.
3) If No then Exit the program, else Step 4.
4) If YES then allow the User to type in his current password, press a button and Windows should remove the password.

Joomla Password Authentication In Visual Basic .NET?
Oct 19, 2011I have managed to successfully connect remotely to the MySQL database for my Joomla! 1.5 website using MySqlConnector in Visual Basic .NET 2010. Now I am trying to authenticate a user's password from values submitted in a simple form to those retrieved from a MySQL query.

Username / Password Authentication For Account Not Currently Logged In
Nov 14, 2011I can access the current Windows user, but I want to give an admin the ability to enter an alternate username and password for a different Windows Active Directory Account without having to logoff and log back in. Once the account is authenticated, I need to use it in a connection string to sql server. I know I could do this for a SQL Server login, but this is Windows Authentication only.

View 2 RepliesUse Windows Authentication In WPF?
Oct 5, 2009how to use Windows Authentication in a WPF app. I wouldn't have thought that it would be any different than in any non-WPF app, but it seems that it is. I want to go into my project Properties -> Application and ensure that Windows Authentication is on, but that option is not available in a WPF app (as the following document confirms).

If I ignore all that and just look at My.User.Name (VB), it is empty. This tells me that somehow Windows Authentication is not enabled.My plan is to use a PrincipalPermission attribute to restrict access to certain parts of my app (or perhaps the entire app, by applying it to Application_Startup()).

Return User Details After Ldap Authentication (asp.net)?
May 15, 2012I am trying to set up a new internal system for my client currently, they insisted on integrating the login with AD, which makes sense, and i have managed that with no problem. However what i also want to do, after authentication, is to store some user details / attributes as session variables. I have the following code to aithenticate the user:
'this function authenticates against AD - very simple and works nicely.
Function AuthenticateUser(path As String, user As String, pass As String) As Boolean
Dim de As New DirectoryEntry(path, user, pass, AuthenticationTypes.Secure)
[code]....
which works nicely, and once the function returns me a True, i set Session("LoggedIn") as True.what i need to do is (hopefully within the above function) save the user's name, and 2 other custom atributes from within the user's AD profile.How would i access those (hypothetically)

C# - Use Authentication In 'Forms' And As Well In 'Windows' For A .net Web Application?
May 14, 2011We have an application in Access for UI and MS Sql server as Database server. We now decided to build a new application in web application for UI. This web application is only used by the employees who work for the company. But later we decided to host this web application on outside server. So the user (from this company only.) can able to login anywhere in the world. First I thought creating the web application using 'windows' authentication thinking we may be using it as an intranet web application. But now my manager asked me to use both 'Forms' and as well as 'Windows' for using this application and this web application will be hosted on outside server. I really don't catch his point of using both types of authentication.
