The rule is that if there are any command line arguments specified
in the sudoers file they need to match what is given by the user.
So, for something like:
user host = /bin/su
The user would be able to run su, su -, su - mysqladmin, etc because
no arguments were specified. You may want something like:
user host = /bin/su mysqladmin, /bin/su - mysqladmin
Note that the '-' is an argument to su and should come before the
user. It's possible you are using a version of su that doesn't
care about the order, though (GNU getopt usually allows flags to
be interspersed with other arguments).
You can also use wildcards like '*', '?', as well as ranges.
