The -B option allows you to enable or disable support of the AUTHENTICATION option with which an authentication method can be negotiated. In BS2000 the AUTHENTICATION option is currently only implemented for TLS.
You can define the settings in the TELNET server which are required for TLS operation using the -Z options described for the START-TLS option (see the section “-Z option - Support of the START-TLS option”).
The options -Z tls required (START-TLS option, see "-Z tls-required") and -B (AUTHENTICATION option) may not be specified simultaneously. If they are, an error message is issued:
Both START-TLS and AUTHENTICATION-Option not allowed
