suid and suse 6.4

hallo, so much for file permissions, but: alexm@quake:/ > id uid=1000(alexm) gid=100(users) groups=100(users) alexm@quake:/ > ls -l sh -rwsr-xr-x 1 root root 387764 Jun 28 00:27 sh* alexm@quake:/ > ./sh alexm@quake:/ > id uid=1000(alexm) gid=100(users) groups=100(users) :-o wasn't i supposed to get euid of root? or does suse's /bin/sh do some checks i am not aware of? thanks, -alexm P.S. btw, just checked it with /usr/bin/ksh and it does give the euid 0.
