Ok, I see. My question was just to ensure minimum security for su acces,even if this is not efective for sudo, like d33tah pointed.

comment Ask root for password when using su command
That's it! Thanks it was commenting the line that says "auth suficient pam_root.so" ans adding the "auth required pam_unix.so". I don't know what exactlly the last command do, but was compulsory to get this work properly. Thanks a lot for your answers.

Maybe this is useless. This is just a question from a lab in my university. I guess this is possible, because you can indicate a user the the commands he can use without password. For instance : gatoatigrado ALL=NOPASSWD: /bin/set-slow-cpufreq
