su is not meant to do that -- sudo is.

Open /etc/sudoers.d/custom and write the following:

user-a ALL=(user-b:user-b) NOPASSWD:ALL

Which means: whenever user-a executes sudo -u user-b (or any other variant), let him go without asking for password.

That worked. All I needed to do than was 'sudo -u user-b bash' – Wojtek Jan 13 '14 at 14:08
"sudo -i -u user-b" worked aswell – Orphans Nov 14 '22 at 13:44
