The dropAllRolesFromDatabase removes all user-defined roles from the database.

The dropAllRolesFromDatabase command takes the following form:

{
  dropAllRolesFromDatabase: 1,
  writeConcern: { <write concern> }
}

The command has the following fields:

Field	Type	Description
`dropAllRolesFromDatabase`	integer	Specify `1` to drop all user-defined roles from the database where the command is run.
`writeConcern`	document	Optional. The level of write concern for the removal operation. The `writeConcern` document takes the same fields as the `getLastError` command.

You must have the dropRole action on a database to drop a role from that database.

The following operations drop all user-defined roles from the products database:

use products
db.runCommand(
   {
     dropAllRolesFromDatabase: 1,
     writeConcern: { w: "majority" }
   }
)

The n field in the results document reports the number of roles dropped:

{ "n" : 4, "ok" : 1 }
