Hi, I am using .net membership provider for authentication purpose. I have the following requirement. If a user first time login to an application and the password hasn’t been changed (assume this user created by admin and the password is provided to user by admin) i should not validate the user until or unless he change the password provided by admin. I dont know how to accompolish this task. I meant how do i come to know tat this is the first time the user login to the application. Is there any property is available in the .net membership provider or any other way. Help would be greatly appreciated With Regards, Anand
