hi,

I need some help to do the following: i want to use a unique
authentication/logon process for Windows XP (instead of the
original Windows logon). This means that before the logon
dialog box appears i want to use my own authentication mechanism
(It uses USB drive as a hardware key, in combination with free
software tools and asymmetric cryptography with a radius server.)
If the authentication fails, /for example no USB drive/ the
original logon dialog box should appear.

Well, some of the main questions are i think:
- how can i execute my own logon application before the windows
logon dialog box appears? (maybe as a service??)
- if the logon succeed, how can i step over the original logon
dialog box and go straight to the desktop?

thx any help in advance
 
Why do you want to do this? Is there something wrong with the existing
choices? Writing your own authentication method is rarely a good idea. It's
some of the most difficult code to write securely.

Help me understand your business or technical need; perhaps I can suggest an
alternative that doesn't require replacing a fundamental component of the
operating system.
 
Well, i'm a student&part of a project in the university where this is the
main problem. But now i know that i should wite my own gina. i hope i can do
this but i'm afraid it won't be easy...

have a nice day
 
Well, first of all, thx for the reply
So, if GINA is not used in Vista then what is?
Is it possible to do the same thing in Vista & if it is, how?

thx in advance
 
Windows Vista and Server 2008 have replaced the GINA with a credential
provider model with a pluggable architecture. Start your research by reading
about the new ICredentialProvider interfaces.

However, I still question the assignment your instructor gave you. What is
he trying to have you learn?
