Hi everyone, I am really finding it hard to figure out this annoying issue with sql server logins. When I try to create a login in my wpf app, it works but I cannot use the username and password to authenticate via sql server authentication in my app. I have disabled the CHECK_POLICY, CHECK_EXPIRATION, MUST_CHANGE options yet, I can't still login. I tried to alter the login via sqlcommand object and it still the same. Then I went to my sql management studio and alter my login password and I tried to connect in my wpf app, and it works this time. The issue here is that, I want my wpf app to be able to do the alter statement because not all app users will have the management studio or they should only be allowed to download the sql server without the management studio which is done internally from the wpf app. Please guys, I need your help, its really urgent. Thanks
