i have a Server with 4 users: a, b, c, admin
I have the plan to enable user a and b to change
to user admin with the command su (without sudo! [Because screen program]) without a password promt.
I had read something about the /etc/sudoers file but nothing which match really with my Problem.
With regards, Tim
Don't create an Account without an password.
It can enable workarounds for users ...
You cannot do this with su. It requires a password, and it should. There is likely another approach you need to take if sudo is not an option. Otherwise they could always sudo -c 'su - admin' sort of thing.
