impersonation

[vineeshV]

I need to impersonate the user to logged in to the system .The process of impersonation should be like this 1) The user will input the username to be impersonate and passwd 2) There will be a dummy user in the system . 3) I need to read all the privilages for the inputted user 4) Then the dummy user will be logged in to the system with all the privilages of the inputted user The purpose of this is whether i inputted administrator or guest user ,the logged user will be dummy with the admin/guest privilges Can any body tell me how can i achieve this The whole thing should be worked in winNT series and winXP series (including vista ) Its a servie application

And for what reason, might I ask, would you want to impersonate a user? Forgive me if your intentions are good, but this sounds like a question better asked at http://www.offensivecomputing.net/[^]
