There are two unix accounts A and B. I want to configure password less ssh between these two accounts.This can be done without much pain but my problem is that there are mutiple accounts like A and B where  I have to the same thing.I also have one admin account C (not root). So,I was thinking if it is possible to setup password less ssh connection between A and B from account C so that I can write a script and run it from account C every time I want do similar activity for different accounts.(Also ,all the accounts have the same password .)
setup password less ssh between two accounts from third account
