YADE should consider alternative and required authentication methods for SFTP

Current Situation

• YADE can be configured to use one of the authentication methods password or publickey for SFTP

Desired Behavior

• YADE should consider to use a second authentication method if a login with the first authentication method failed for SFTP
  • introducing of the new configuration item - PreferredAuthentications
• YADE should consider to use both authentication methods for a session. This configuration is used if an SFTP server is configured to require more than one authentication method to be used (AuthenticationMethods, RequiredAuthentications2).
  • introducing of the new configuration item - RequiredAuthentications
• Use of a second authentication method includes support for use of a Credential Store.
• The YADE XSD schema should be adjusted to reflect use of additional authentication methods.
• PreferredAuthentications, RequiredAuthentications should be supported when using a jump host.

Examples

• The attached configuration files show the desired use of settings:
  • YADE-462.ini: "classic" configuration by manually editing .ini files
  • YADE-462.xml: current configuration as created by the XML Editor.
• Both .ini and .xml examples include use of settings that should be supported by YADE-462 (the examples will not work with current YADE releases:
  • allow a number of authentication methods, e.g. publickey, password
  • allow the password and authentication file parameters in parallel.
