su(substituting user) in linux

[kuldeep vyas]

Hi David,

I'm using Redhat 9 (kernel 2.4.20-8 on i686)
I logged in as k(username), then I started terminal, &
then I gave following commands

k>su
password:
          // after giving password user is substituted

             (root)
root>su k
password:
          // after giving password user is substituted

             (k)
k>su
password:
         // now after giving password I don't get a   
            response from terminal
If I exit from my first su (of root),then everything
is OK, but why I'm not allowed to substitute user as &
when required. Is it a bug or my approach of
substituting user is not correct?

Happy contributing to LINUX!!
