How to reset forgotten adminstrative password?
There is no booting problem for me. But, when the computer goes to sleeping mode it asks me for password. As I cannot provide it I have to force-shutdown the computer. I got some tips in reply to my question from some other websites. Acting accordingly finally I got the reply "authentication token manipulation error .... password not changed".
I have almost no experience in working in a non-graphic screen. So, please give the answer in detail step by step manner suitable for an illiterate.
