I have already tried sudo before writing my own setuid-root-program, by 
calling it directly from pam_exec and by letting pam_exec call another 
program first that calls sudo. Either case failed, even with simple 
tests like letting sudo run /bin/ls (and of course I checked before that 
the same user could use sudo from the command line).
