Tectia Server 4.x (and earlier) required an authorization file that listed the user public keys that are authorized for login. Using the authorization file with Tectia Server 5.0 and later is optional. If the file does not exist, Tectia Server looks for authorized public keys in the authorized-keys directory (as described in User Authentication with Public Keys above), and if that fails, in the default directory for user public-keys.

The default location for the authorization file is $HOME/.ssh2/authorization on Unix, and %USERPROFILE%\.ssh2\authorization on Windows. The file 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) under the section called “Files”.

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