Definition

revokeRolesFromUser

Removes one or more roles from a user on the database where the roles exist.

Tip

In mongosh, this command can also be run through the db.revokeRolesFromUser() helper method.

Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.

Compatibility

This command is available in deployments hosted in the following environments:

  • MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

Important

This command is not supported in M0, M2, M5, and M10+ clusters. For more information, see Unsupported Commands.

Syntax

The command has the following syntax:

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

Command Fields

The command takes 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 operation. See Write Concern Specification.

comment

any

Optional. A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations:

A comment can be any valid BSON type (string, integer, object, array, etc).

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

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"
    }
]
