I am currently running linuxmint and openssh. I have 2 accounts on my computer Joe and Bob. I have the keys and passphrase created by joe stored in the /home/joe/.ssh/ folder. I can connect to Joe using ssh/sftp. but I can not connect to Bob. My question is do I have to create a new set of keys for Bob in order to connect to him even though both accounts are on the same machine? Also I have tried to chroot jail for sftp users (Subsystem sftp internal-sftp) I get locked out of BOTH accounts when trying to use it. It worked when I was using a password instead of a key passphrase.
