SSH Tectia Server 4.x (and earlier) require an authorization file that lists the user public keys that are authorized for login. Using the authorization file with SSH Tectia Server 5.x is optional. If the file does not exist, SSH Tectia Server looks for authorized keys in the authorized_keys directory as described in User Authentication with Public Keys above.

The default location for the authorization file is $HOME/.ssh2/authorization on Unix and %USERPROFILE%\.ssh2\authorization on Windows. The default location can be changed with the authorization-file attribute in the ssh-server-config.xml file. See auth-publickey.

The authorization file contains a list of public key filenames each preceded by the keyword Key. If there is more than one Key, they are all authorized for login. For more information on the syntax of the authorization file, see $HOME/.ssh2/authorization (user-specific).

SSH Tectia Client on Windows can upload the public keys and edit the authorization file automatically.
