You can changing the log level of sshd by modifying /etc/ssh/sshd_config(search LogLevel, set it to DEBUG), then check the output in /var/log/auth.log to see what happened exactly.

For security reasons, avoid using the same password as you use to log in to your account. Should I report it? After that password authentication is still impossible, but user is not locked anymore. –user3132194 Apr 7 at 11:53 add a comment| up vote 3 down vote We ran into the same Ssh Key Based Authentication Linux share|improve this answer edited Jun 16 '11 at 19:37 answered Jun 16 '11 at 18:54 fche 1,572816 add a comment| up vote 5 down vote Beware that SELinux can trigger this

With SELinux enabled this feature does not work.

If your private key is passphrase-protected, you'll need to give ssh (client) the passphrase every time. SSHD only has permissions to open specific kinds of files (and other objects) according to its policy. For instance, to make /other-disk/home useable as a root for user home directories, one can run:Code:# semanage fcontext -a -t home_root_t /other-disk/home# semanage fcontext -a -e /home /other-disk/homeThen, restorecon will apply
