rolesInfo

Returns inheritance and privilege information for specified roles, including both user-defined roles and built-in roles.

The rolesInfo command can also retrieve all roles scoped to a database.

Compatibility

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

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

Note

This command is supported in all MongoDB Atlas clusters. For information on all commands, see Unsupported Commands.

MongoDB Enterprise: The subscription-based, self-managed version of MongoDB
MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Syntax

The command has the following syntax:

db.runCommand(
   {
     rolesInfo: { role: <name>, db: <db> },
     showAuthenticationRestrictions: <Boolean>,
     showBuiltinRoles: <Boolean>,
     showPrivileges: <Boolean>,
     comment: <any>
   }
)

Command Fields

The command takes the following fields:

Field	Type	Description
`rolesInfo`	string, document, array, or integer	The role(s) to return information about. For the syntax for specifying roles, see Behavior.
`showAuthenticationRestrictions`	boolean	Optional. Set this field to `true` to include authentication restrictions in the output. Authentication restrictions indicate the IP addresses that users with this role can connect to and from. By default, this field is `false`, meaning that the `rolesInfo` output does not include authentication restrictions.
`showBuiltinRoles`	boolean	Optional. When the `rolesInfo` field is set to `1`, set `showBuiltinRoles` to `true` to include built-in roles in the output. By default, this field is set to `false`, and the output for `rolesInfo: 1` displays only user-defined roles.
`showPrivileges`	boolean	Optional. Set the field to `true` to show role privileges, including both privileges inherited from other roles and privileges defined directly. By default, the command returns only the roles from which this role inherits privileges and does not return specific privileges.
`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: mongod log messages, in the `attr.command.cursor.comment` field. Database profiler output, in the `command.comment` field. `currentOp` output, in the `command.comment` field. A comment can be any valid BSON type (string, integer, object, array, etc).

Behavior

Return Information for a Single Role

To specify a role from the current database, specify the role by its name:

{ rolesInfo: "<rolename>" }

To specify a role from another database, specify the role by a document that specifies the role and database:

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

Return Information for Multiple Roles

To specify multiple roles, use an array. Specify each role in the array as a document or string. Use a string only if the role exists on the database on which the command runs:

{
  rolesInfo: [
     "<rolename>",
     { role: "<rolename>", db: "<database>" },
     ...
  ]
}

Return Information for All Roles in the Database

To specify all roles in the database on which the command runs, specify rolesInfo: 1. By default MongoDB displays all the user-defined roles in the database. To include built-in roles as well, include the parameter-value pair showBuiltinRoles: true:

{ rolesInfo: 1, showBuiltinRoles: true }

Required Access

To view a role's information, you must be either explicitly granted the role or must have the viewRole action on the role's database.

Output

rolesInfo.role: The name of the role.

rolesInfo.db: The database on which the role is defined. Every database has built-in roles. A database might also have user-defined roles.

rolesInfo.isBuiltin: A value of true indicates the role is a built-in role. A value of false indicates the role is a user-defined role.

rolesInfo.roles: The roles that directly provide privileges to this role and the databases on which the roles are defined.

rolesInfo.inheritedRoles: All roles from which this role inherits privileges. This includes the roles in the rolesInfo.roles array as well as the roles from which the roles in the rolesInfo.roles array inherit privileges. All privileges apply to the current role. The documents in this field list the roles and the databases on which they are defined.

rolesInfo.privileges

The privileges directly specified by this role; i.e. the array excludes privileges inherited from other roles. By default the output does not include the privileges field. To include the field, specify showPrivileges: true when running the rolesInfo command.

Each privilege document specifies the resources and the actions allowed on the resources.

rolesInfo.inheritedPrivileges

All privileges granted by this role, including those inherited from other roles. By default the output does not include the inheritedPrivileges field. To include the field, specify showPrivileges: true when running the rolesInfo command.

Each privilege document specifies the resources and the actions allowed on the resources.

View Information for a Single Role

The following command returns the role inheritance information for the role associate defined in the products database:

db.runCommand(
    {
      rolesInfo: { role: "associate", db: "products" }
    }
)

The following command returns the role inheritance information for the role siteManager on the database on which the command runs:

db.runCommand(
    {
      rolesInfo: "siteManager"
    }
)

The following command returns both the role inheritance and the privileges for the role associate defined on the products database:

db.runCommand(
    {
      rolesInfo: { role: "associate", db: "products" },
      showPrivileges: true
    }
)

View Information for Multiple Roles

The following command returns information for two roles on two different databases:

db.runCommand(
    {
      rolesInfo: [
         { role: "associate", db: "products" },
         { role: "manager", db: "resources" }
      ]
    }
)

The following returns both the role inheritance and the privileges:

db.runCommand(
    {
      rolesInfo: [
         { role: "associate", db: "products" },
         { role: "manager", db: "resources" }
      ],
      showPrivileges: true
    }
)

View All User-Defined Roles for a Database

The following operation returns all user-defined roles on the database on which the command runs and includes privileges:

db.runCommand(
    {
      rolesInfo: 1,
      showPrivileges: true
    }
)

Example output (shortened for readability):

{
  roles: [
    {
      _id: 'products.associate',
      role: 'associate',
      db: 'products',
      privileges: [
        {
          resource: { db: 'products', collection: '' },
          actions: [ 'bypassDocumentValidation' ]
        }
      ],
      roles: [ { role: 'readWrite', db: 'products' } ],
      isBuiltin: false,
      inheritedRoles: [ { role: 'readWrite', db: 'products' } ],
      inheritedPrivileges: [
        {
          resource: { db: 'products', collection: '' },
          actions: [ 'bypassDocumentValidation' ]
        },
        {
          resource: { db: 'products', collection: '' },
          actions: [
            'changeStream',
            'collStats',
            'compactStructuredEncryptionData',
            ...
          ]
        },
        ...
      ]
    }
  ],
  ok: 1
}

View All User-Defined and Built-In Roles for a Database

The following operation returns all roles on the database on which the command runs, including both built-in and user-defined roles:

db.runCommand(
    {
      rolesInfo: 1,
      showBuiltinRoles: true
    }
)

Example output (shortened for readability):

{
  roles: [
    {
      role: 'enableSharding',
      db: 'products',
      isBuiltin: true,
      roles: [],
      inheritedRoles: []
    },
    {
      role: 'userAdmin',
      db: 'products',
      isBuiltin: true,
      roles: [],
      inheritedRoles: []
    },
    {
      role: 'read',
      db: 'products',
      isBuiltin: true,
      roles: [],
      inheritedRoles: []
    },
    ...
  ],
  ok: 1
}

View Authentication Restrictions for Roles

The following operation returns all user-defined roles on the products database and includes authentication restrictions:

db.runCommand(
    {
      rolesInfo: 1,
      showAuthenticationRestrictions: true
    }
)

Example output:

{
  roles: [
    {
      _id: 'products.associate',
      role: 'associate',
      db: 'products',
      roles: [ { role: 'readWrite', db: 'products' } ],
      authenticationRestrictions: [
        [ { clientSource: [ '198.51.100.0' ] } ]
      ],
      isBuiltin: false,
      inheritedRoles: [ { role: 'readWrite', db: 'products' } ],
      inheritedAuthenticationRestrictions: [
        [ { clientSource: [ '198.51.100.0' ] } ]
      ]
    }
  ],
  ok: 1
}
