 """ start connection negotiation This method starts the connection negotiation process by telling the client the protocol version that the server proposes, along with a list of security mechanisms which the client can use for authentication. RULE: If the client cannot handle the protocol version suggested by the server it MUST close the socket connection. RULE: The server MUST provide a protocol version that is lower than or equal to that requested by the client in the protocol header. If the server cannot support the specified protocol it MUST NOT send this method, but MUST close the socket connection. PARAMETERS: version_major: octet protocol major version The protocol major version that the server agrees to use, which cannot be higher than the client's major version. version_minor: octet protocol major version The protocol minor version that the server agrees to use, which cannot be higher than the client's minor version. server_properties: table server properties mechanisms: longstr available security mechanisms A list of the security mechanisms that the server supports, delimited by spaces. Currently ASL supports these mechanisms: PLAIN. locales: longstr available message locales A list of the message locales that the server supports, delimited by spaces. The locale defines the language in which the server will send reply texts. RULE: All servers MUST support at least the en_US locale. """
