revokeRolesFromUser

Definition

revokeRolesFromUser

Removes a one or more roles from a user on the database where the roles exist. The revokeRolesFromUser command uses the following syntax:

{ revokeRolesFromUser: "<user>",
  roles: [
    { role: "<role>", db: "<database>" } | "<role>",
    ...
  ],
  writeConcern: { <write concern> }
}

The command has the following fields:

Field Type Description
revokeRolesFromUser string The user to remove roles from.
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 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.

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 revokeRolesFromUser command 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 command runs:

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

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

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