SSH authorized_keys Global Include
Is it possible to 'include' a global SSH authorized_keys file?
For example, I have user accounts user1,user2,user3 and my user name is Benjamin. I want to be able to use my ssh key to authenticate as each of these users. I can manually copy my key to each .ssh/authorized_keys file individually, but is there a way to simply include /home/Benjamin/.ssh/global_authorized_keys in each of these user's authorized_keys file without manually adding and removing?
