Resolution

The AUTH command is used to initialize a secure connection to the connected FTP server. Included with this command is a case-insensitive parameter defining the security mechanism that the client is requesting to use to secure the session. Example security mechanisms used by popular FTP clients are SSL and TLS. This command should be followed by a USER command to authenticate the access to the server after establishing a secure channel. This command is not used to secure the connection if secure connections are implicitly required by the server (usually done by allowing connections on port 990).
