Overview

This class is for apps that need to manage User Accounts, Groups, or OAuth Client Registrations. It provides access to the SCIM endpoints on the UAA. For more information about SCIM – the IETF’s System for Cross-domain Identity Management (formerly known as Simple Cloud Identity Management) – see http://www.simplecloud.info.

The types of objects and links to their schema are as follows:

Naming attributes by type of object:

  • :user is “username”

  • :group is “displayname”

  • :client is “client_id”

#initialize(target, auth_header, options = {}) ⇒ Scim

Returns a new instance of Scim.

Parameters:

  • auth_header (String) —

    a string that can be used in an authorization header. For OAuth2 with JWT tokens this would be something like “bearer xxxx.xxxx.xxxx”. The TokenInfo class provides TokenInfo#auth_header for this purpose.

  • options (Hash) (defaults to: {}) —

    can be

    • :symbolize_keys, if true, returned hash keys are symbols.

Parameters:

  • type (Symbol) —

#change_password(user_id, new_password, old_password = nil) ⇒ Hash

Change password.

  • For a user to change their own password, the token in @auth_header must contain “password.write” scope and the correct old_password must be given.

  • For an admin to set a user’s password, the token in @auth_header must contain “uaa.admin” scope.

Parameters:

  • user_id (String) —

    the CF::UAA::Scim id attribute of the user

Returns:

  • (Hash) —

    success message from server

end

#change_secret(client_id, new_secret, old_secret = nil) ⇒ Hash
