The directory has mode 700 and the file hast 600. Restricting these any
further could result in a problem. :-)

Ok, I did that. Now it works! :-)

The problem was not the authorized_keys file itself, it was my home
directory. This had mode 770, which seemed fine to me as it is owned
by christian:christian. Making it group-readable shouldn't pose a
security problem, as only I will be in this group. However, sshd didn't
see it that way, it seems. Now that I changed it to 750, all is 
fine. :-)

Thanks für your help!

Good night!
