that sounds like a straightforward sudo setup.  
1. install sudo
2. add users to some group (group "sumo", in example below)
3. add a line something like this to /etc/sudoers:

%sumo	ALL = (userA) NOPASSWD: ALL

from left to right, anyone in group "sumo" can execute on any machine,
as user "userA", without a password, and they can execute any command.
the man pages for sudoers should have some pretty extensive examples.
