.ssh/authorized_keys2 is deprecated

Hi,

the documentation for "OpenSSH Server" for Ubuntu 8.10 mentions .ssh/authorized_keys2 as the file where to add a user's public key for the public key based authentication (https://help.ubuntu.com/8.10/serverguide/C/openssh-server.html#openssh-keys). However, according to to http://sial.org/howto/openssh/#s6, that file "has been deprecated since the OpenSSH 3.0 release (2001)". (Though it still "works" as expected in my Ubuntu 8.10 installation.)

Could you please check this and adjust the documenation accordingly?

Thanks and best regards
Heiko
