You are correct, yes login should be su, and while we don't want the
users to su to become root we do need them to su to become other users.
I did the sudo -l and go the following;
(ALL) /bin/su [-]?*
(ALL) !/bin/su [-]*root*
(ALL) /usr/sbin/su [-]?*
(ALL) !/usr/sbin/su [-]*root*
Plus more but that's just different directories.
It's ok if you are sleep-deprived, you work in IT it's expected
