(NIS ID's) The common usernames are not an issue. I have the same username on client and server most of the time. Based on your description, it sounds like you've ONLY tested user_A -> user_B, and user_A -> user_A. So the point of failure is not "user names are the same", but rather, "user_A on the server". Which leads me to suspect you have incorrect permissions (or an invalid key) in user_A's home directory. I have some hints here: http://wooledge.org/mywiki/SshKeys
