Im writing code to allow users to login to Windows XP using their cell phone. My problem is that once I have completed my user credential verification (using certificates on the cell phone) I need to log the user into XP. I want to log the username 'x' into the same user account he would normally have loged into by typing his password in.
However in my cell phone login I do not have the password(not safe to store them on cellphones). Is there anyway to tell XP to allow user x to log into his account without knowing his password. I need this authentication scheme to exists side by side with the normal user login.
