}

The dropUser command document has the following fields:

Field字段	Type类型	Description描述
dropUser	string	The name of the user to delete. You must issue the dropUser command while using the database where the user exists.
writeConcern	document	Optional.可选。The level of write concern for the removal operation. The writeConcern document takes the same fields as the getLastError command.

Once set, this comment appears alongside records of this command in the following locations: mongod log messages, in the attr.command.cursor.comment field.
