The connection to the FTP server is protected by a security mechanism. Anonymous logins are supported by the FTP server for protected sessions only when the FTP.DATA file statement ANONYMOUSLEVEL has a parameter that is greater than two.
The anonymous login fails.
Contact the system programmer with the error.
To allow anonymous logins with an active security mechanism, give the ANONYMOUSLEVEL statement in FTP.DATA a parameter value greater than two. See the z/OS Communications Server: IP Configuration Reference for information about the ANONYMOUSLEVEL statement.
