db.revokeRolesFromUser()¶

Removes a one or more roles from a user on the current database. The db.revokeRolesFromUser() method uses the following syntax:

db.revokeRolesFromUser( "<username>", [ <roles> ], { <writeConcern> } )

The revokeRolesFromUser method takes the following arguments:

Parameter	Type	Description
`user`	string	The name of the user from whom to revoke roles.
`roles`	array	The roles to remove from the user.
`writeConcern`	document	Optional. The level of write concern for the modification. The `writeConcern` document takes the same fields as the `getLastError` command.

In the roles field, you can specify both built-in roles and user-defined role.

To specify a role that exists in the same database where db.revokeRolesFromUser() runs, you can either specify the role with the name of the role:

"readWrite"

Or you can specify the role with a document, as in:

{ role: "<role>", db: "<database>" }

To specify a role that exists in a different database, specify the role with a document.

The db.revokeRolesFromUser() method wraps the revokeRolesFromUser command.

Required Access¶

You must have the revokeRole action on a database to revoke a role on that database.

Example¶

The accountUser01 user in the products database has the following roles:

"roles" : [
    { "role" : "assetsReader",
      "db" : "assets"
    },
    { "role" : "read",
      "db" : "stock"
    },
    { "role" : "readWrite",
      "db" : "products"
    }
]

The following db.revokeRolesFromUser() method removes the two of the user’s roles: the read role on the stock database and the readWrite role on the products database, which is also the database on which the method runs:

use products
db.revokeRolesFromUser( "accountUser01",
                        [ { role: "read", db: "stock" }, "readWrite" ],
                        { w: "majority" }
                      )

The user accountUser01 user in the products database now has only one remaining role:

"roles" : [
    { "role" : "assetsReader",
      "db" : "assets"
    }
]
