You can set security parameters when you create a connection with create connection.
Normally, you use create connection to add connections to non-Sybase databases.
create connection to data_server.database... set username [to] user [set password [to] passwd] [set security_mechanism [to] 'mechanism_name' | set dsi_exec_request_sproc [to] { 'on' | 'off' } | set security_mechanism [to] 'mechanism_name' | set security_parameter [to] { 'required' | 'not_required' } ]
In addition to security configuration parameters you can set with create connection, you can set the dsi_exec_request_sproc special security parameters.
Connections parameters are stored in the rs_config table in the RSSD, and you must have sa permission to execute them.
Security parameters set at both ends of a connection must be compatible.
