I want to use LDAP to integrate my application with Windows authentication. As long as the user has already logged in with the Win2000 domain, my application does not require the user to input password anymore. Could anyone tell me whether this is fesible, and if possible provide me a hint on how to do it? I know that Win2000 provides the Active Directory as a LDAP server. My application can get the user password, and then asks the Active Directory to authenticate whether the password is the same as the Win2000 password. But what I want is not like this. I want my application even does not need to ask for any password. Much appreciated for providing the help. Regards, Roy    More>>
