Problem with "su"

[dbeux]

Yop,

 

I'll try to change place of "su" form /bin to /home/specuser/bin for security.

(mv /bin/su /home/specuser/bin )

then I have logged myself like specuser and I've tried to use "su" ex. : su (enter)

                                                                                                     <root passwd>

and the message "su: Mot de passe incorrect." appeared.

 

Ok! I thought then I moved again su from /home/specuser/bin to /bin and tried

again to use "su" but the same message is appeared.

 

What to do to repare the problem ?

Why do the su when I execute it from an oder rep (directory) ?

 

Help help help ???

 

thank's in advance for you answer.
