ssh will not allow passwordless logins (using key pairs) unless the users home directory permissions conform to a specific criteria. But all users share a home directory which means that the criteria cannot be satisfied. I have tried adding a user in the usual Linux manner (adduser) but it gets deleted the next time the web interface is used (as you would expect I suppose). What I need to do is change the new user script that is run when adding a user in the web interface. Does anyone know where that script is so that I may edit it?
