Using Keys Generated with OpenSSH

If the user has an existing OpenSSH authorized_keys file on the server, the ssh-keygen-g3 tool can be used to import the OpenSSH authorized_keys file and to configure the authorization file, for example:

SERVER> ssh-keygen-g3 --import-ssh1-authorized-key 
$HOME/.ssh/authorized_keys $HOME/.ssh2/authorization

Imported key /home/user/.ssh/authorized_keys:1 to 
/home/user/.ssh2/imported-437b1a07-1.pub and added to authorization file 
Imported key /home/user/.ssh/authorized_keys:2 to 
/home/user/.ssh2/imported-437b1a07-2.pub and added to authorization file 

For more information on the ssh-keygen-g3 options, see the ssh-keygen-g3 man page.

Alternatively, the administrator of Tectia Server may enable AuthorizedKeysFile in the server configuration file /opt/tectia/etc/sshd2_config, for example as follows:

AuthorizedKeysFile %D/.ssh/authorized_keys

Tectia Server will check the defined AuthorizedKeysFile in addition to the user's AuthorizationFile (by default $HOME/.ssh2/authorization). Note that the AuthorizationFile has precedence over AuthorizedKeysFile if the same key is defined in both.
