Sudoers question

Hello again! I have some users sysadmin users that i do not want to be
checked for rights. I have setup my sudoers file like this:
# User privilege specification
# You should not use sudo as root in an SELinux environment
# If you use SELinux, remove the following line
root ALL=(ALL) ALL
userhere ALL=(ALL) ALL
userhere ALL=(ALL) ALL

The root entry, of course, works but the other entries do not work (they
are prompted to enter the root password.) Thanks for any help!
